+# This file is in the public domain, so clarified as of
+# 2009-05-17 by Arthur David Olson.
+
+# This data is by no means authoritative; if you think you know better,
+# go ahead and edit the file (and please send any changes to
+# tz@iana.org for general use in the future).
+
+# From Paul Eggert (2006-03-22):
+#
+# A good source for time zone historical data outside the U.S. is
+# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
+# San Diego: ACS Publications, Inc. (2003).
+#
+# Gwillim Law writes that a good source
+# for recent time zone data is the International Air Transport
+# Association's Standard Schedules Information Manual (IATA SSIM),
+# published semiannually.  Law sent in several helpful summaries
+# of the IATA's data after 1990.
+#
+# Except where otherwise noted, Shanks & Pottenger is the source for
+# entries through 1990, and IATA SSIM is the source for entries afterwards.
+#
+# Another source occasionally used is Edward W. Whitman, World Time Differences,
+# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
+# I found in the UCLA library.
+#
+# A reliable and entertaining source about time zones is
+# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
+#
+# Previous editions of this database used WAT, CAT, SAT, and EAT
+# for +0:00 through +3:00, respectively,
+# but Mark R V Murray reports that
+# `SAST' is the official abbreviation for +2:00 in the country of South Africa,
+# `CAT' is commonly used for +2:00 in countries north of South Africa, and
+# `WAT' is probably the best name for +1:00, as the common phrase for
+# the area that includes Nigeria is ``West Africa''.
+# He has heard of ``Western Sahara Time'' for +0:00 but can find no reference.
+#
+# To make things confusing, `WAT' seems to have been used for -1:00 long ago;
+# I'd guess that this was because people needed _some_ name for -1:00,
+# and at the time, far west Africa was the only major land area in -1:00.
+# This usage is now obsolete, as the last use of -1:00 on the African
+# mainland seems to have been 1976 in Western Sahara.
+#
+# To summarize, the following abbreviations seem to have some currency:
+#	-1:00	WAT	West Africa Time (no longer used)
+#	 0:00	GMT	Greenwich Mean Time
+#	 2:00	CAT	Central Africa Time
+#	 2:00	SAST	South Africa Standard Time
+# and Murray suggests the following abbreviation:
+#	 1:00	WAT	West Africa Time
+# I realize that this leads to `WAT' being used for both -1:00 and 1:00
+# for times before 1976, but this is the best I can think of
+# until we get more information.
+#
+# I invented the following abbreviations; corrections are welcome!
+#	 2:00	WAST	West Africa Summer Time
+#	 2:30	BEAT	British East Africa Time (no longer used)
+#	 2:45	BEAUT	British East Africa Unified Time (no longer used)
+#	 3:00	CAST	Central Africa Summer Time (no longer used)
+#	 3:00	SAST	South Africa Summer Time (no longer used)
+#	 3:00	EAT	East Africa Time
+#	 4:00	EAST	East Africa Summer Time (no longer used)

+# It seems that Mauritius observed daylight saving time from 1982-10-10 to

+
+# From Arthur David Olson (2008-06-30):
+# The www.timeanddate.com article cited by Steffen Thorsen notes that "A

+
+# From Paul Eggert (2008-06-30):
+# Follow Thorsen on DST in 1982/1983, instead of Shanks & Pottenger.

+# According to
+# 
+# http://www.lexpress.mu/display_article.php?news_id=111216
+# 
+# (in French), Mauritius will start and end their DST a few days earlier
+# than previously announced (2008-11-01 to 2009-03-31).  The new start
+# date is 2008-10-26 at 02:00 and the new end date is 2009-03-27 (no time
+# given, but it is probably at either 2 or 3 wall clock time).
+#
+# A little strange though, since the article says that they moved the date
+# to align itself with Europe and USA which also change time on that date,
+# but that means they have not paid attention to what happened in
+# USA/Canada last year (DST ends first Sunday in November). I also wonder
+# why that they end on a Friday, instead of aligning with Europe which
+# changes two days later.
+

+# Tunisia
+
+# From Gwillim Law (2005-04-30):
+# My correspondent, Risto Nykanen, has alerted me to another adoption of DST,
+# this time in Tunisia.  According to Yahoo France News
+# , in a story attributed to AP
+# and dated 2005-04-26, "Tunisia has decided to advance its official time by
+# one hour, starting on Sunday, May 1.  Henceforth, Tunisian time will be
+# UTC+2 instead of UTC+1.  The change will take place at 23:00 UTC next
+# Saturday."  (My translation)
+#
+# From Oscar van Vlijmen (2005-05-02):
+# LaPresse, the first national daily newspaper ...
+# 
+# ... DST for 2005: on: Sun May 1 0h standard time, off: Fri Sept. 30,
+# 1h standard time.
+#
+# From Atef Loukil (2006-03-28):
+# The daylight saving time will be the same each year:
+# Beginning      : the last Sunday of March at 02:00
+# Ending         : the last Sunday of October at 03:00 ...
+# http://www.tap.info.tn/en/index.php?option=com_content&task=view&id=1188&Itemid=50

+# From Arthur David Olson (2009--3-18):
+# The Tunis Afrique Presse News Agency notice contains this: "This measure is due to the fact

+# Therefore, the standard time will be kept unchanged the whole year long."
+# So foregoing DST seems to be an exception (albeit one that may be repeated in the  future).

+# According to some news reports Tunis confirmed not to use DST in 2010
+#
+# (translation):

+
+# From Steffen Thorsen (2010-03-10):
+# We got these changes from the Australian Antarctic Division:
+# - Macquarie Island will stay on UTC+11 for winter and therefore not
+# switch back from daylight savings time when other parts of Australia do
+# on 4 April.
+#
+# - Casey station reverted to its normal time of UTC+8 on 5 March 2010.
+# The change to UTC+11 is being considered as a regular summer thing but
+# has not been decided yet.
+#
+# - Davis station will revert to its normal time of UTC+7 at 10 March 2010
+# 20:00 UTC.
+#
+# - Mawson station stays on UTC+5.
+#
+# In addition to the Rule changes for Casey/Davis, it means that Macquarie
+# will no longer be like Hobart and will have to have its own Zone created.

+# time, which is 12 hours ahead of GMT. The Russian Station Vostok was

+# natural time zone is in between the two: 8 hours ahead of GMT.''

+# time so that noon is the warmest part of the day, and that this
+# changes during the year and does not necessarily correspond to mean
+# solar noon.  So the Vostok time might have been whatever the clocks
+# happened to be during their visit.  So we still don't really know what time
+# it is at Vostok.  But we'll guess UTC+6.

+# From Guy Harris:
+# People's Republic of China.  Yes, they really have only one time zone.
+
+# From Bob Devine (1988-01-28):
+# No they don't.  See TIME mag, 1986-02-17 p.52.  Even though
+# China is across 4 physical time zones, before Feb 1, 1986 only the
+# Peking (Bejing) time zone was recognized.  Since that date, China
+# has two of 'em -- Peking's and Urumqi (named after the capital of
+# the Xinjiang Uyghur Autonomous Region).  I don't know about DST for it.
+#
+# . . .I just deleted the DST table and this editor makes it too
+# painful to suck in another copy..  So, here is what I have for
+# DST start/end dates for Peking's time zone (info from AP):
+#
+#     1986 May 4 - Sept 14
+#     1987 mid-April - ??

+

+# boundaries summarized below]....  A few other exceptions were two

+# (could be true), for the moment I am assuming that those two
+# counties are mistakes in the astro.com data.
+
+# From Paul Eggert (2008-02-11):
+# I just now checked Google News for western news sources that talk
+# about China's single time zone, and couldn't find anything before 1986
+# talking about China being in one time zone.  (That article was: Jim
+# Mann, "A clumsy embrace for another western custom: China on daylight
+# time--sort of", Los Angeles Times, 1986-05-05.  By the way, this
+# article confirms the tz database's data claiming that China began
+# observing daylight saving time in 1986.
+#
+# From Thomas S. Mullaney (2008-02-11):
+# I think you're combining two subjects that need to treated
+# separately: daylight savings (which, you're correct, wasn't
+# implemented until the 1980s) and the unified time zone centered near
+# Beijing (which was implemented in 1949). Briefly, there was also a
+# "Lhasa Time" in Tibet and "Urumqi Time" in Xinjiang. The first was
+# ceased, and the second eventually recognized (again, in the 1980s).
+#
+# From Paul Eggert (2008-06-30):
+# There seems to be a good chance China switched to a single time zone in 1949

+# From Luther Ma (2009-10-17):
+# Almost all (>99.9%) ethnic Chinese (properly ethnic Han) living in
+# Xinjiang use Chinese Standard Time. Some are aware of Xinjiang time,
+# but have no need of it. All planes, trains, and schools function on
+# what is called "Beijing time." When Han make an appointment in Chinese
+# they implicitly use Beijing time.
+#
+# On the other hand, ethnic Uyghurs, who make up about half the
+# population of Xinjiang, typically use "Xinjiang time" which is two
+# hours behind Beijing time, or UTC +0600. The government of the Xinjiang
+# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as
+# local governments such as the Urumqi city government use both times in
+# publications, referring to what is popularly called Xinjiang time as
+# "Urumqi time." When Uyghurs make an appointment in the Uyghur language
+# they almost invariably use Xinjiang time.
+#
+# (Their ethnic Han compatriots would typically have no clue of its
+# widespread use, however, because so extremely few of them are fluent in
+# Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.)
+#
+# (...As with the rest of China there was a brief interval ending in 1990
+# or 1991 when summer time was in use.  The confusion was severe, with
+# the province not having dual times but four times in use at the same
+# time. Some areas remained on standard Xinjiang time or Beijing time and
+# others moving their clocks ahead.)

+#
+# 1. Wulumuqi...
+# 2. Kashi...

+#
+# 6. Likewise for Kashgar and the rest of south Xinjiang I don't know of any

+#
+# Without having access to local historical records, nor the ability to legally

+# From Paul Eggert (1994-11-19):
+# Today's _Economist_ (p 60) reports that Georgia moved its clocks forward
+# an hour recently, due to a law proposed by Zurab Murvanidze,
+# an MP who went on a hunger strike for 11 days to force discussion about it!
+# We have no details, but we'll guess they didn't move the clocks back in fall.
+#
+# From Mathew Englander, quoting AP (1996-10-23 13:05-04):
+# Instead of putting back clocks at the end of October, Georgia
+# will stay on daylight savings time this winter to save energy,
+# President Eduard Shevardnadze decreed Wednesday.
+#
+# From the BBC via Joseph S. Myers (2004-06-27):
+#
+# Georgia moved closer to Western Europe on Sunday...  The former Soviet
+# republic has changed its time zone back to that of Moscow.  As a result it
+# is now just four hours ahead of Greenwich Mean Time, rather than five hours
+# ahead.  The switch was decreed by the pro-Western president of Georgia,
+# Mikhail Saakashvili, who said the change was partly prompted by the process
+# of integration into Europe.
+
+# From Teimuraz Abashidze (2005-11-07):
+# Government of Georgia ... decided to NOT CHANGE daylight savings time on
+# [Oct.] 30, as it was done before during last more than 10 years.
+# Currently, we are in fact GMT +4:00, as before 30 October it was GMT
+# +3:00.... The problem is, there is NO FORMAL LAW or governmental document
+# about it.  As far as I can find, I was told, that there is no document,
+# because we just DIDN'T ISSUE document about switching to winter time....
+# I don't know what can be done, especially knowing that some years ago our
+# DST rules where changed THREE TIMES during one month.

+
+# From Joao Carrascalao, brother of the former governor of East Timor, in
+# 
+# East Timor may be late for its millennium
+#  (1999-12-26/31):
+# Portugal tried to change the time forward in 1974 because the sun
+# rises too early but the suggestion raised a lot of problems with the
+# Timorese and I still don't think it would work today because it
+# conflicts with their way of life.
+
+# From Paul Eggert (2000-12-04):
+# We don't have any record of the above attempt.
+# Most likely our records are incomplete, but we have no better data.
+
+# 
+# From Manoel de Almeida e Silva, Deputy Spokesman for the UN Secretary-General
+# (2000-08-16):
+# The Cabinet of the East Timor Transition Administration decided
+# today to advance East Timor's time by one hour.  The time change,
+# which will be permanent, with no seasonal adjustment, will happen at
+# midnight on Saturday, September 16.

+# Iran
+
+# From Roozbeh Pournader (2003-03-15):
+# This is an English translation of what I just found (originally in Persian).
+# The Gregorian dates in brackets are mine:
+#
+#	Official Newspaper No. 13548-1370/6/25 [1991-09-16]
+#	No. 16760/T233 H				1370/6/10 [1991-09-01]
+#
+#	The Rule About Change of the Official Time of the Country
+#
+#	The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14],
+#	based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13]
+#	of the Country's Organization for Official and Employment Affairs,
+#	and referring to the law for equating the working hours of workers
+#	and officers in the whole country dated 1359/4/23 [1980-07-14], and
+#	for synchronizing the official times of the country, agreed that:
+#
+#	The official time of the country will should move forward one hour
+#	at the 24[:00] hours of the first day of Farvardin and should return
+#	to its previous state at the 24[:00] hours of the 30th day of
+#	Shahrivar.
+#
+#	First Deputy to the President - Hassan Habibi
+#
+# From personal experience, that agrees with what has been followed
+# for at least the last 5 years.  Before that, for a few years, the
+# date used was the first Thursday night of Farvardin and the last
+# Thursday night of Shahrivar, but I can't give exact dates....
+# I have also changed the abbreviations to what is considered correct
+# here in Iran, IRST for regular time and IRDT for daylight saving time.
+#
+# From Roozbeh Pournader (2005-04-05):
+# The text of the Iranian law, in effect since 1925, clearly mentions
+# that the true solar year is the measure, and there is no arithmetic
+# leap year calculation involved.  There has never been any serious
+# plan to change that law....
+#
+# From Paul Eggert (2006-03-22):
+# Go with Shanks & Pottenger before Sept. 1991, and with Pournader thereafter.
+# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,
+# stopping after 2037 when 32-bit time_t's overflow.
+# That cal-persia used Birashk's approximation, which disagrees with the solar
+# calendar predictions for the year 2025, so I corrected those dates by hand.
+#
+# From Oscar van Vlijmen (2005-03-30), writing about future
+# discrepancies between cal-persia and the Iranian calendar:
+# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
+# the vernal equinox and that gets so close to 12:00 some local
+# Iranian time that the definition of the correct location needs to be
+# known exactly, amongst other factors.  2157 is even closer:
+# 2157-03-20 08:37:15.5 UT.  But the Gregorian year 2025 should give
+# no interpretation problem whatsoever.  By the way, another instant
+# in the near future where there will be a discrepancy between
+# arithmetical and astronomical Iranian calendars will be in 2058:
+# vernal equinox on 2058-03-20 09:03:05.9 UT.  The Java version of
+# Reingold's/Dershowitz' calculator gives correctly the Gregorian date
+# 2058-03-21 for 1 Farvardin 1437 (astronomical).
+#
+# From Steffen Thorsen (2006-03-22):
+# Several of my users have reported that Iran will not observe DST anymore:
+# http://www.irna.ir/en/news/view/line-17/0603193812164948.htm
+#
+# From Reuters (2007-09-16), with a heads-up from Jesper Norgaard Welen:
+# ... the Guardian Council ... approved a law on Sunday to re-introduce
+# daylight saving time ...
+# http://uk.reuters.com/article/oilRpt/idUKBLA65048420070916
+#
+# From Roozbeh Pournader (2007-11-05):
+# This is quoted from Official Gazette of the Islamic Republic of
+# Iran, Volume 63, Number 18242, dated Tuesday 1386/6/24
+# [2007-10-16]. I am doing the best translation I can:...
+# The official time of the country will be moved forward for one hour
+# on the 24 hours of the first day of the month of Farvardin and will
+# be changed back to its previous state on the 24 hours of the
+# thirtieth day of Shahrivar.

+# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
+# the U.S. edition) on the Iraqi Kurds contains a paragraph:
+# "The three northern provinces ... switched their clocks this spring and
+# are an hour ahead of Baghdad."
+#
+# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
+# In the past, some Kurdish nationalists, as a protest to the Iraqi
+# Government, did not adhere to daylight saving time.  They referred
+# to daylight saving as Saddam time.  But, as of today, the time zone
+# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
+#
+# So we'll ignore the Economist's claim.

+# Israel
+
+# From Ephraim Silverberg (2001-01-11):
+#
+# I coined "IST/IDT" circa 1988.  Until then there were three
+# different abbreviations in use:
+#
+# JST  Jerusalem Standard Time [Danny Braniss, Hebrew University]
+# IZT  Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
+# EEST Eastern Europe Standard Time [used by almost everyone else]
+#
+# Since timezones should be called by country and not capital cities,
+# I ruled out JST.  As Israel is in Asia Minor and not Eastern Europe,
+# EEST was equally unacceptable.  Since "zonal" was not compatible with
+# any other timezone abbreviation, I felt that 'IST' was the way to go
+# and, indeed, it has received almost universal acceptance in timezone
+# settings in Israeli computers.
+#
+# In any case, I am happy to share timezone abbreviations with India,
+# high on my favorite-country list (and not only because my wife's
+# family is from India).

+# (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17, 2000-07-25, 2004-12-22,
+# and 2005-02-17):
+
+# According to the Office of the Secretary General of the Ministry of
+# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
+# One thing is entrenched in law, however: that there must be at least 150
+# days of daylight savings time annually.  From 1993-1998, the change to
+# daylight savings time was on a Friday morning from midnight IST to
+# 1 a.m IDT; up until 1998, the change back to standard time was on a
+# Saturday night from midnight daylight savings time to 11 p.m. standard
+# time.  1996 is an exception to this rule where the change back to standard
+# time took place on Sunday night instead of Saturday night to avoid
+# conflicts with the Jewish New Year.  In 1999, the change to
+# daylight savings time was still on a Friday morning but from
+# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
+# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
+# 1999 only.  In the year 2000, the change to daylight savings time was
+# similar to 1999, but although the change back will be on a Friday, it
+# will take place from 1 a.m. IDT to midnight IST.  Starting in 2001, all
+# changes to/from will take place at 1 a.m. old time, but now there is no
+# rule as to what day of the week it will take place in as the start date
+# (except in 2003) is the night after the Passover Seder (i.e. the eve
+# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
+# (except in 2002) is three nights before Yom Kippur [Day of Atonement]
+# (the eve of the 7th of Tishrei in the lunar Hebrew calendar).

+
+# From Mayumi Negishi in the 2005-08-10 Japan Times
+# :
+# Occupation authorities imposed daylight-saving time on Japan on
+# [1948-05-01]....  But lack of prior debate and the execution of
+# daylight-saving time just three days after the bill was passed generated
+# deep hatred of the concept....  The Diet unceremoniously passed a bill to

+
+# From Hideyuki Suzuki (1998-11-16):
+# The ordinance No. 51 (1886) established "standard time" in Japan,
+# which stands for the time on E 135 degree.
+# In the ordinance No. 167 (1895), "standard time" was renamed to "central

+
+# From Paul Eggert (1996-11-22):
+# Andrew Evtichov (1996-04-13) writes that Kazakhstan
+# stayed in sync with Moscow after 1990, and that Aqtobe (formerly Aktyubinsk)
+# and Aqtau (formerly Shevchenko) are the largest cities in their zones.
+# Guess that Aqtau and Aqtobe diverged in 1995, since that's the first time
+# IATA SSIM mentions a third time zone in Kazakhstan.
+
+# From Paul Eggert (2006-03-22):
+# German Iofis, ELSI, Almaty (2001-10-09) reports that Kazakhstan uses
+# RussiaAsia rules, instead of switching at 00:00 as the IATA has it.
+# Go with Shanks & Pottenger, who have them always using RussiaAsia rules.
+# Also go with the following claims of Shanks & Pottenger:
+#
+# - Kazakhstan did not observe DST in 1991.
+# - Qyzylorda switched from +5:00 to +6:00 on 1992-01-19 02:00.
+# - Oral switched from +5:00 to +4:00 in spring 1989.
+
+# 
+# From Kazakhstan Embassy's News Bulletin #11 (2005-03-21):
+# 
+# The Government of Kazakhstan passed a resolution March 15 abolishing
+# daylight saving time citing lack of economic benefits and health
+# complications coupled with a decrease in productivity.
+#
+# From Branislav Kojic (in Astana) via Gwillim Law (2005-06-28):
+# ... what happened was that the former Kazakhstan Eastern time zone
+# was "blended" with the Central zone.  Therefore, Kazakhstan now has
+# two time zones, and difference between them is one hour.  The zone
+# closer to UTC is the former Western zone (probably still called the
+# same), encompassing four provinces in the west: Aqtobe, Atyrau,
+# Mangghystau, and West Kazakhstan.  The other zone encompasses
+# everything else....  I guess that would make Kazakhstan time zones

+
+# From Oscar van Vlijmen (1999-12-11):
+# 
+# General Information Mongolia
+#  (1999-09)
+# "Time: Mongolia has two time zones. Three westernmost provinces of
+# Bayan-Ulgii, Uvs, and Hovd are one hour earlier than the capital city, and
+# the rest of the country follows the Ulaanbaatar time, which is UTC/GMT plus
+# eight hours."
+
+# From Rives McDow (1999-12-13):
+# Mongolia discontinued the use of daylight savings time in 1999; 1998
+# being the last year it was implemented.  The dates of implementation I am
+# unsure of, but most probably it was similar to Russia, except for the time
+# of implementation may have been different....
+# Some maps in the past have indicated that there was an additional time
+# zone in the eastern part of Mongolia, including the provinces of Dornod,
+# Suhbaatar, and possibly Khentij.
+
+# From Paul Eggert (1999-12-15):
+# Naming and spelling is tricky in Mongolia.
+# We'll use Hovd (also spelled Chovd and Khovd) to represent the west zone;
+# the capital of the Hovd province is sometimes called Hovd, sometimes Dund-Us,
+# and sometimes Jirgalanta (with variant spellings), but the name Hovd
+# is good enough for our purposes.
+
+# From Rives McDow (2001-05-13):
+# In addition to Mongolia starting daylight savings as reported earlier
+# (adopted DST on 2001-04-27 02:00 local time, ending 2001-09-28),
+# there are three time zones.
+#
+# Provinces [at 7:00]: Bayan-ulgii, Uvs, Khovd, Zavkhan, Govi-Altai
+# Provinces [at 8:00]: Khovsgol, Bulgan, Arkhangai, Khentii, Tov,
+#	Bayankhongor, Ovorkhangai, Dundgovi, Dornogovi, Omnogovi
+# Provinces [at 9:00]: Dornod, Sukhbaatar
+#
+# [The province of Selenge is omitted from the above lists.]
+
+# From Ganbold Ts., Ulaanbaatar (2004-04-17):
+# Daylight saving occurs at 02:00 local time last Saturday of March.
+# It will change back to normal at 02:00 local time last Saturday of
+# September.... As I remember this rule was changed in 2001.
+#
+# From Paul Eggert (2004-04-17):
+# For now, assume Rives McDow's informant got confused about Friday vs
+# Saturday, and that his 2001 dates should have 1 added to them.
+
+# From Paul Eggert (2005-07-26):
+# We have wildly conflicting information about Mongolia's time zones.
+# Bill Bonnet (2005-05-19) reports that the US Embassy in Ulaanbaatar says
+# there is only one time zone and that DST is observed, citing Microsoft
+# Windows XP as the source.  Risto Nykanen (2005-05-16) reports that
+# travelmongolia.org says there are two time zones (UTC+7, UTC+8) with no DST.
+# Oscar van Vlijmen (2005-05-20) reports that the Mongolian Embassy in
+# Washington, DC says there are two time zones, with DST observed.
+# He also found
+# 
+# which also says that there is DST, and which has a comment by "Toddius"
+# (2005-03-31 06:05 +0700) saying "Mongolia actually has 3.5 time zones.
+# The West (OLGII) is +7 GMT, most of the country is ULAT is +8 GMT
+# and some Eastern provinces are +9 GMT but Sukhbaatar Aimag is SUHK +8.5 GMT.
+# The SUKH timezone is new this year, it is one of the few things the
+# parliament passed during the tumultuous winter session."
+# For now, let's ignore this information, until we have more confirmation.
+
+# From Ganbold Ts. (2007-02-26):
+# Parliament of Mongolia has just changed the daylight-saving rule in February.
+# They decided not to adopt daylight-saving time....

+
+# From Deborah Goldsmith (2008-03-30):
+# We received a bug report claiming that the tz database UTC offset for

+# http://www.eznis.com/Container.jsp?id=112
+#

+#
+# There it appears that flights between Choibalsan and Ulaanbatar arrive

+
+# From Rives McDow (2002-03-13):
+# I have been advised that Pakistan has decided to adopt dst on a
+# TRIAL basis for one year, starting 00:01 local time on April 7, 2002
+# and ending at 00:01 local time October 6, 2002.  This is what I was
+# told, but I believe that the actual time of change may be 00:00; the
+# 00:01 was to make it clear which day it was on.

+# Jesper Norgaard found this URL:
+# http://www.pak.gov.pk/public/news/app/app06_dec.htm

+# advance the clocks by one hour on the night between the first
+# Saturday and Sunday of April and revert to the original position on
+# 15th October each year".  This agrees with McDow's 04-07 at 00:00,
+# but disagrees about the October transition, and makes it sound like
+# it's not on a trial basis.  Also, the "between the first Saturday

+# Palestine
+
+# From Amos Shapir (1998-02-15):
+#
+# From 1917 until 1948-05-15, all of Palestine, including the parts now
+# known as the Gaza Strip and the West Bank, was under British rule.
+# Therefore the rules given for Israel for that period, apply there too...
+#
+# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
+# (except a short occupation by Israel from 1956-11 till 1957-03, but no
+# time zone was affected then).  It was never formally annexed to Egypt,
+# though.
+#
+# The rest of Palestine was under Jordanian rule at that time, formally
+# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
+# the country's previous name of "the Hashemite Kingdom of the
+# Trans-Jordan").  So the rules for Jordan for that time apply.  Major
+# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
+# East Jerusalem.
+#
+# Both areas were occupied by Israel in June 1967, but not annexed (except
+# for East Jerusalem).  They were on Israel time since then; there might
+# have been a Military Governor's order about time zones, but I'm not aware
+# of any (such orders may have been issued semi-annually whenever summer
+# time was in effect, but maybe the legal aspect of time was just neglected).
+#
+# The Palestinian Authority was established in 1993, and got hold of most
+# towns in the West Bank and Gaza by 1995.  I know that in order to
+# demonstrate...independence, they have been switching to
+# summer time and back on a different schedule than Israel's, but I don't
+# know when this was started, or what algorithm is used (most likely the
+# Jordanian one).
+#
+# To summarize, the table should probably look something like that:
+#
+# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
+# ------------+-----------+-----------+-----------+-----------
+# Israel      | Zion      | Zion      | Zion      | Zion
+# West bank   | Zion      | Jordan    | Zion      | Jordan
+# Gaza        | Zion      | Egypt     | Zion      | Jordan
+#
+# I guess more info may be available from the PA's web page (if/when they
+# have one).
+
+# From Paul Eggert (2006-03-22):
+# Shanks & Pottenger write that Gaza did not observe DST until 1957, but go
+# with Shapir and assume that it observed DST from 1940 through 1947,
+# and that it used Jordanian rules starting in 1996.
+# We don't yet need a separate entry for the West Bank, since
+# the only differences between it and Gaza that we know about
+# occurred before our cutoff date of 1970.
+# However, as we get more information, we may need to add entries
+# for parts of the West Bank as they transitioned from Israel's rules
+# to Palestine's rules.
+
+# From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time,
+# forwarded by Ephraim Silverberg:
+#
+# Despite the fact that Israel changed over to daylight savings time
+# last week, the PLO Authority (PA) has decided not to turn its clocks
+# one-hour forward at this time.  As a sign of independence from Israeli rule,
+# the PA has decided to implement DST in April.
+
+# From Paul Eggert (1999-09-20):
+# Daoud Kuttab writes in
+# 
+# Holiday havoc
+#  (Jerusalem Post, 1999-04-22) that
+# the Palestinian National Authority changed to DST on 1999-04-15.
+# I vaguely recall that they switch back in October (sorry, forgot the source).
+# For now, let's assume that the spring switch was at 24:00,
+# and that they switch at 0:00 on the 3rd Fridays of April and October.
+
+# From Paul Eggert (2005-11-22):
+# Starting 2004 transitions are from Steffen Thorsen's web site timeanddate.com.
+
+# From Steffen Thorsen (2005-11-23):
+# A user from Gaza reported that Gaza made the change early because of
+# the Ramadan.  Next year Ramadan will be even earlier, so I think
+# there is a good chance next year's end date will be around two weeks
+# earlier--the same goes for Jordan.
+
+# From Steffen Thorsen (2006-08-17):
+# I was informed by a user in Bethlehem that in Bethlehem it started the
+# same day as Israel, and after checking with other users in the area, I
+# was informed that they started DST one day after Israel.  I was not
+# able to find any authoritative sources at the time, nor details if
+# Gaza changed as well, but presumed Gaza to follow the same rules as

+
+# From Paul Eggert (2007-09-20):
+# My understanding is that Gaza and the West Bank disagree even over when
+# the weekend is (Thursday+Friday versus Friday+Saturday), so I'd be a bit
+# surprised if they agreed about DST.  But for now, assume they agree.

+# no longer available as of 1999-08-17)
+# reported ``the country's standard time will be put forward by one hour at
+# midnight Friday (1830 GMT) `in the light of the present power crisis'.''
+#
+# From Dharmasiri Senanayake, Sri Lanka Media Minister (1996-10-24), as quoted
+# by Shamindra in
+# 
+# Daily News - Hot News Section (1996-10-26)
+# :
+# With effect from 12.30 a.m. on 26th October 1996
+# Sri Lanka will be six (06) hours ahead of GMT.
+
+# From Jesper Norgaard Welen (2006-04-14), quoting Sri Lanka News Online
+#  (2006-04-13):
+# 0030 hrs on April 15, 2006 (midnight of April 14, 2006 +30 minutes)
+# at present, become 2400 hours of April 14, 2006 (midnight of April 14, 2006).
+
+# From Peter Apps and Ranga Sirila of Reuters (2006-04-12) in:
+# 
+# [The Tamil Tigers] never accepted the original 1996 time change and simply
+# kept their clocks set five and a half hours ahead of Greenwich Mean
+# Time (GMT), in line with neighbor India.
+# From Paul Eggert (2006-04-18):
+# People who live in regions under Tamil control can use [TZ='Asia/Kolkata'],
+# as that zone has agreed with the Tamil areas since our cutoff date of 1970.
+
+# From K Sethu (2006-04-25):
+# I think the abbreviation LKT originated from the world of computers at
+# the time of or subsequent to the time zone changes by SL Government
+# twice in 1996 and probably SL Government or its standardization
+# agencies never declared an abbreviation as a national standard.
+#
+# I recollect before the recent change the government annoucemments
+# mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka
+# Time and no mention was made about the abbreviation.
+#
+# If we look at Sri Lanka Department of Government's "Official News
+# Website of Sri Lanka" ... http://www.news.lk/ we can see that they
+# use SLT as abbreviation in time stamp at the beginning of each news
+# item....
+#
+# Within Sri Lanka I think LKT is well known among computer users and
+# adminsitrators.  In my opinion SLT may not be a good choice because the
+# nation's largest telcom / internet operator Sri Lanka Telcom is well
+# known by that abbreviation - simply as SLT (there IP domains are
+# slt.lk and sltnet.lk).
+#
+# But if indeed our government has adopted SLT as standard abbreviation
+# (that we have not known so far) then  it is better that it be used for
+# all computers.
+
+# From Paul Eggert (2006-04-25):
+# One possibility is that we wait for a bit for the dust to settle down
+# and then see what people actually say in practice.

+# AN ACT to provide for the change to standard time in Samoa and to make

+#
+# 1. Short title and commencement-(1) This Act may be cited as the

+# 4. Samoa standard time - (1) Upon the commencement of this Act, Samoa

+#  summarizes daylight saving issues in Australia.
+
+# From Arthur David Olson (2005-12-12):
+# 
+# Lawlink NSW:Daylight Saving in New South Wales
+#  covers New South Wales in particular.
+
+# From John Mackin (1991-03-06):
+# We in Australia have _never_ referred to DST as `daylight' time.
+# It is called `summer' time.  Now by a happy coincidence, `summer'
+# and `standard' happen to start with the same letter; hence, the
+# abbreviation does _not_ change...
+# The legislation does not actually define abbreviations, at least
+# in this State, but the abbreviation is just commonly taken to be the
+# initials of the phrase, and the legislation here uniformly uses
+# the phrase `summer time' and does not use the phrase `daylight
+# time'.
+# Announcers on the Commonwealth radio network, the ABC (for Australian
+# Broadcasting Commission), use the phrases `Eastern Standard Time'
+# or `Eastern Summer Time'.  (Note, though, that as I say in the
+# current australasia file, there is really no such thing.)  Announcers
+# on its overseas service, Radio Australia, use the same phrases
+# prefixed by the word `Australian' when referring to local times;
+# time announcements on that service, naturally enough, are made in UTC.
+
+# From Arthur David Olson (1992-03-08):
+# Given the above, what's chosen for year-round use is:
+#	CST	for any place operating at a GMTOFF of 9:30
+#	WST	for any place operating at a GMTOFF of 8:00
+#	EST	for any place operating at a GMTOFF of 10:00
+
+# From Chuck Soper (2006-06-01):
+# I recently found this Australian government web page on time zones:
+# 
+# And this government web page lists time zone names and abbreviations:
+# 
+
+# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST"
+# versus "AEST" etc.:
+#
+# I see the following points of dispute:
+#
+# * How important are unique time zone abbreviations?
+#
+#   Here I tend to agree with the point (most recently made by Chris
+#   Newman) that unique abbreviations should not be essential for proper
+#   operation of software.  We have other instances of ambiguity
+#   (e.g. "IST" denoting both "Israel Standard Time" and "Indian
+#   Standard Time"), and they are not likely to go away any time soon.
+#   In the old days, some software mistakenly relied on unique
+#   abbreviations, but this is becoming less true with time, and I don't
+#   think it's that important to cater to such software these days.
+#
+#   On the other hand, there is another motivation for unambiguous
+#   abbreviations: it cuts down on human confusion.  This is
+#   particularly true for Australia, where "EST" can mean one thing for
+#   time T and a different thing for time T plus 1 second.
+#
+# * Does the relevant legislation indicate which abbreviations should be used?
+#
+#   Here I tend to think that things are a mess, just as they are in
+#   many other countries.  We Americans are currently disagreeing about
+#   which abbreviation to use for the newly legislated Chamorro Standard
+#   Time, for example.
+#
+#   Personally, I would prefer to use common practice; I would like to
+#   refer to legislation only for examples of common practice, or as a
+#   tiebreaker.
+#
+# * Do Australians more often use "Eastern Daylight Time" or "Eastern
+#   Summer Time"?  Do they typically prefix the time zone names with
+#   the word "Australian"?
+#
+#   My own impression is that both "Daylight Time" and "Summer Time" are
+#   common and are widely understood, but that "Summer Time" is more
+#   popular; and that the leading "A" is also common but is omitted more
+#   often than not.  I just used AltaVista advanced search and got the
+#   following count of page hits:
+#
+#     1,103 "Eastern Summer Time" AND domain:au
+#       971 "Australian Eastern Summer Time" AND domain:au
+#       613 "Eastern Daylight Time" AND domain:au
+#       127 "Australian Eastern Daylight Time" AND domain:au
+#
+#   Here "Summer" seems quite a bit more popular than "Daylight",
+#   particularly when we know the time zone is Australian and not US,
+#   say.  The "Australian" prefix seems to be popular for Eastern Summer
+#   Time, but unpopular for Eastern Daylight Time.
+#
+#   For abbreviations, tools like AltaVista are less useful because of
+#   ambiguity.  Many hits are not really time zones, unfortunately, and
+#   many hits denote US time zones and not Australian ones.  But here
+#   are the hit counts anyway:
+#
+#     161,304 "EST" and domain:au
+#      25,156 "EDT" and domain:au
+#      18,263 "AEST" and domain:au
+#      10,416 "AEDT" and domain:au
+#
+#      14,538 "CST" and domain:au
+#       5,728 "CDT" and domain:au
+#         176 "ACST" and domain:au
+#          29 "ACDT" and domain:au
+#
+#       7,539 "WST" and domain:au
+#          68 "AWST" and domain:au
+#
+#   This data suggest that Australians tend to omit the "A" prefix in
+#   practice.  The situation for "ST" versus "DT" is less clear, given
+#   the ambiguities involved.
+#
+# * How do Australians feel about the abbreviations in the tz database?
+#
+#   If you just count Australians on this list, I count 2 in favor and 3
+#   against.  One of the "against" votes (David Keegel) counseled delay,
+#   saying that both AEST/AEDT and EST/EST are widely used and
+#   understood in Australia.
+
+# From Paul Eggert (1995-12-19):
+# Shanks & Pottenger report 2:00 for all autumn changes in Australia and NZ.
+# Mark Prior writes that his newspaper
+# reports that NSW's fall 1995 change will occur at 2:00,
+# but Robert Elz says it's been 3:00 in Victoria since 1970
+# and perhaps the newspaper's `2:00' is referring to standard time.
+# For now we'll continue to assume 2:00s for changes since 1960.
+
+# From Eric Ulevik (1998-01-05):
+#
+# Here are some URLs to Australian time legislation. These URLs are stable,
+# and should probably be included in the data file. There are probably more

+# The most interesting region I have found consists of three towns on the

+# Australia does not.  The two states are one and a half hours apart.  The
+# residents decided to forget about this nonsense of changing the clock so
+# much and set the local time 20 hours and 45 minutes from the
+# international date line, or right in the middle of the time of South
+# Australia and Western Australia....

+#
+# From Alex Livingston (2006-12-07):
+# ... it was just on four years ago that I drove along the Eyre Highway,
+# which passes through eastern Western Australia close to the southern
+# coast of the continent.
+#
+# I paid particular attention to the time kept there. There can be no
+# dispute that UTC+08:45 was considered "the time" from the border
+# village just inside the border with South Australia to as far west
+# as just east of Caiguna. There can also be no dispute that Eucla is
+# the largest population centre in this zone....
+#
+# Now that Western Australia is observing daylight saving, the
+# question arose whether this part of the state would follow suit. I
+# just called the border village and confirmed that indeed they have,
+# meaning that they are now observing UTC+09:45.
+#
+# (2006-12-09):
+# I personally doubt that either experimentation with daylight saving
+# in WA or its introduction in SA had anything to do with the genesis

+# Lord Howe Island is located off the New South Wales coast, and is half an
+# hour ahead of NSW time.
+
+# From James Lonergan, Secretary, Lord Howe Island Board (2000-01-27):
+# Lord Howe Island summer time in 2000/2001 will commence on the same
+# date as the rest of NSW (i.e. 2000-08-27).  For your information the
+# Lord Howe Island Board (controlling authority for the Island) is
+# seeking the community's views on various options for summer time
+# arrangements on the Island, e.g. advance clocks by 1 full hour
+# instead of only 30 minutes.  [Dependent] on the wishes of residents
+# the Board may approach the NSW government to change the existing
+# arrangements.  The starting date for summer time on the Island will
+# however always coincide with the rest of NSW.
+
+# From James Lonergan, Secretary, Lord Howe Island Board (2000-10-25):
+# Lord Howe Island advances clocks by 30 minutes during DST in NSW and retards
+# clocks by 30 minutes when DST finishes. Since DST was most recently
+# introduced in NSW, the "changeover" time on the Island has been 02:00 as
+# shown on clocks on LHI. I guess this means that for 30 minutes at the start
+# of DST, LHI is actually 1 hour ahead of the rest of NSW.
+
+# From Paul Eggert (2006-03-22):
+# For Lord Howe dates we use Shanks & Pottenger through 1989, and
+# Lonergan thereafter.  For times we use Lonergan.
+
+# From Paul Eggert (2007-07-23):
+# See "southeast Australia" above for 2008 and later.
+
+# From Steffen Thorsen (2009-04-28):
+# According to the official press release, South Australia's extended daylight
+# saving period will continue with the same rules as used during the 2008-2009
+# summer (southern hemisphere).
+#
+# From
+# 
+# http://www.safework.sa.gov.au/uploaded_files/DaylightDatesSet.pdf
+# 
+# The extended daylight saving period that South Australia has been trialling
+# for over the last year is now set to be ongoing.
+# Daylight saving will continue to start on the first Sunday in October each
+# year and finish on the first Sunday in April the following year.
+# Industrial Relations Minister, Paul Caica, says this provides South Australia
+# with a consistent half hour time difference with NSW, Victoria, Tasmania and
+# the ACT for all 52 weeks of the year...

+
+# From Rives McDow (1999-11-08):

+#
+# ... I have also seen Pitcairn listed as UTC minus 9 hours in several
+# references, and can only assume that this was an error in interpretation
+# somehow in light of this proclamation.
+
+# From Rives McDow (1999-11-09):
+# The Proclamation regarding Pitcairn time came into effect on 27 April 1998
+# ... at midnight.
+
+# From Howie Phelps (1999-11-10), who talked to a Pitcairner via shortwave:

+
+
+# Tonga
+
+# From Paul Eggert (1996-01-22):
+# Today's _Wall Street Journal_ (p 1) reports that ``Tonga has been plotting
+# to sneak ahead of [New Zealanders] by introducing daylight-saving time.''
+# Since Kiribati has moved the Date Line it's not clear what Tonga will do.
+
+# Don Mundell writes in the 1997-02-20 Tonga Chronicle
+# 
+# How Tonga became `The Land where Time Begins'
+# :
+
+# Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST
+# 12 hours and 20 minutes ahead of GMT.  When New Zealand adjusted its
+# standard time in 1940s, Tonga had the choice of subtracting from its
+# local time to come on the same standard time as New Zealand or of
+# advancing its time to maintain the differential of 13 degrees
+# (approximately 50 minutes ahead of New Zealand time).
+#
+# Because His Majesty King Taufa'ahau Tupou IV, then Crown Prince
+# Tungi, preferred to ensure Tonga's title as the land where time
+# begins, the Legislative Assembly approved the latter change.
+#
+# But some of the older, more conservative members from the outer
+# islands objected. "If at midnight on Dec. 31, we move ahead 40
+# minutes, as your Royal Highness wishes, what becomes of the 40
+# minutes we have lost?"
+#
+# The Crown Prince, presented an unanswerable argument: "Remember that
+# on the World Day of Prayer, you would be the first people on Earth
+# to say your prayers in the morning."
+
+# From Paul Eggert (2006-03-22):
+# Shanks & Pottenger say the transition was on 1968-10-01; go with Mundell.
+
+# From Eric Ulevik (1999-05-03):
+# Tonga's director of tourism, who is also secretary of the National Millenium
+# Committee, has a plan to get Tonga back in front.
+# He has proposed a one-off move to tropical daylight saving for Tonga from
+# October to March, which has won approval in principle from the Tongan
+# Government.
+
+# From Steffen Thorsen (1999-09-09):
+# * Tonga will introduce DST in November
+#
+# I was given this link by John Letts:
+# 
+# http://news.bbc.co.uk/hi/english/world/asia-pacific/newsid_424000/424764.stm
+# 
+#
+# I have not been able to find exact dates for the transition in November
+# yet. By reading this article it seems like Fiji will be 14 hours ahead
+# of UTC as well, but as far as I know Fiji will only be 13 hours ahead
+# (12 + 1 hour DST).
+
+# From Arthur David Olson (1999-09-20):
+# According to 
+# http://www.tongaonline.com/news/sept1799.html
+# :
+# "Daylight Savings Time will take effect on Oct. 2 through April 15, 2000
+# and annually thereafter from the first Saturday in October through the
+# third Saturday of April.  Under the system approved by Privy Council on
+# Sept. 10, clocks must be turned ahead one hour on the opening day and
+# set back an hour on the closing date."
+# Alas, no indication of the time of day.
+
+# From Rives McDow (1999-10-06):
+# Tonga started its Daylight Saving on Saturday morning October 2nd at 0200am.
+# Daylight Saving ends on April 16 at 0300am which is Sunday morning.
+
+# From Steffen Thorsen (2000-10-31):
+# Back in March I found a notice on the website http://www.tongaonline.com
+# that Tonga changed back to standard time one month early, on March 19
+# instead of the original reported date April 16. Unfortunately, the article
+# is no longer available on the site, and I did not make a copy of the
+# text, and I have forgotten to report it here.
+# (Original URL was: http://www.tongaonline.com/news/march162000.htm )
+
+# From Rives McDow (2000-12-01):
+# Tonga is observing DST as of 2000-11-04 and will stop on 2001-01-27.
+
+# From Sione Moala-Mafi (2001-09-20) via Rives McDow:
+# At 2:00am on the first Sunday of November, the standard time in the Kingdom
+# shall be moved forward by one hour to 3:00am.  At 2:00am on the last Sunday
+# of January the standard time in the Kingdom shall be moved backward by one
+# hour to 1:00am.

+# From Pulu 'Anau (2002-11-05):

+
+
+# Wake
+
+# From Vernice Anderson, Personal Secretary to Philip Jessup,
+# US Ambassador At Large (oral history interview, 1971-02-02):
+#
+# Saturday, the 14th [of October, 1950] -- ...  The time was all the
+# more confusing at that point, because we had crossed the
+# International Date Line, thus getting two Sundays.  Furthermore, we
+# discovered that Wake Island had two hours of daylight saving time
+# making calculation of time in Washington difficult if not almost
+# impossible.
+#
+# http://www.trumanlibrary.org/wake/meeting.htm
+

+# We have no other report of DST in Wake Island, so omit this info for now.

+
+# The International Date Line
+
+# From Gwillim Law (2000-01-03):
+#
+# The International Date Line is not defined by any international standard,
+# convention, or treaty.  Mapmakers are free to draw it as they please.
+# Reputable mapmakers will simply ensure that every point of land appears on
+# the correct side of the IDL, according to the date legally observed there.
+#
+# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and
+# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL
+# to the east side of the Phoenix and Line Islands), I suppose that most
+# mapmakers redrew the IDL following the boundary of Kiribati.  Even that line
+# has a rather arbitrary nature.  The straight-line boundaries between Pacific
+# island nations that are shown on many maps are based on an international
+# convention, but are not legally binding national borders.... The date is
+# governed by the IDL; therefore, even on the high seas, there may be some
+# places as late as fourteen hours later than UTC.  And, since the IDL is not
+# an international standard, there are some places on the high seas where the
+# correct date is ambiguous.
+
+# From Wikipedia  (2005-08-31):
+# Before 1920, all ships kept local apparent time on the high seas by setting
+# their clocks at night or at the morning sight so that, given the ship's
+# speed and direction, it would be 12 o'clock when the Sun crossed the ship's
+# meridian (12 o'clock = local apparent noon).  During 1917, at the
+# Anglo-French Conference on Time-keeping at Sea, it was recommended that all
+# ships, both military and civilian, should adopt hourly standard time zones
+# on the high seas.  Whenever a ship was within the territorial waters of any
+# nation it would use that nation's standard time.  The captain was permitted
+# to change his ship's clocks at a time of his choice following his ship's
+# entry into another zone time--he often chose midnight.  These zones were
+# adopted by all major fleets between 1920 and 1925 but not by many
+# independent merchant ships until World War II.
+
+# From Paul Eggert, using references suggested by Oscar van Vlijmen
+# (2005-03-20):
+#
+# The American Practical Navigator (2002)
+# 
+# talks only about the 180-degree meridian with respect to ships in
+# international waters; it ignores the international date line.

+# We use POSIX-style signs in the Zone names and the output abbreviations,
+# even though this is the opposite of what many people expect.
+# POSIX has positive signs west of Greenwich, but many people expect
+# positive signs east of Greenwich.  For example, TZ='Etc/GMT+4' uses
+# the abbreviation "GMT+4" and corresponds to 4 hours behind UTC
+# (i.e. west of Greenwich) even though many people would expect it to
+# mean 4 hours ahead of UTC (i.e. east of Greenwich).
+#
+# In the draft 5 of POSIX 1003.1-200x, the angle bracket notation allows for
+# TZ='+4'; if you want time zone abbreviations conforming to
+# ISO 8601 you can use TZ='<-0400>+4'.  Thus the commonly-expected
+# offset is kept within the angle bracket (and is used for display)
+# while the POSIX sign is kept outside the angle bracket (and is used
+# for calculation).
+#
+# Do not use a TZ setting like TZ='GMT+4', which is four hours behind
+# GMT but uses the completely misleading abbreviation "GMT".
+
+# Earlier incarnations of this package were not POSIX-compliant,
+# and had lines such as
+#		Zone	GMT-12		-12	-	GMT-1200
+# We did not want things to change quietly if someone accustomed to the old
+# way does a
+#		zic -l GMT-12

+
+# Britain (United Kingdom) and Ireland (Eire)
+
+# From Peter Ilieve (1994-07-06):
+#
+# On 17 Jan 1994 the Independent, a UK quality newspaper, had a piece about
+# historical vistas along the Thames in west London. There was a photo
+# and a sketch map showing some of the sightlines involved. One paragraph
+# of the text said:
+#
+# `An old stone obelisk marking a forgotten terrestrial meridian stands
+# beside the river at Kew. In the 18th century, before time and longitude
+# was standardised by the Royal Observatory in Greenwich, scholars observed
+# this stone and the movement of stars from Kew Observatory nearby. They
+# made their calculations and set the time for the Horse Guards and Parliament,
+# but now the stone is obscured by scrubwood and can only be seen by walking
+# along the towpath within a few yards of it.'
+#
+# I have a one inch to one mile map of London and my estimate of the stone's
+# position is 51 deg. 28' 30" N, 0 deg. 18' 45" W. The longitude should
+# be within about +-2". The Ordnance Survey grid reference is TQ172761.
+#
+# [This yields GMTOFF = -0:01:15 for London LMT in the 18th century.]
+
+# From Paul Eggert (1993-11-18):
+#
+# Howse writes that Britain was the first country to use standard time.
+# The railways cared most about the inconsistencies of local mean time,
+# and it was they who forced a uniform time on the country.
+# The original idea was credited to Dr. William Hyde Wollaston (1766-1828)
+# and was popularized by Abraham Follett Osler (1808-1903).
+# The first railway to adopt London time was the Great Western Railway
+# in November 1840; other railways followed suit, and by 1847 most
+# (though not all) railways used London time.  On 1847-09-22 the
+# Railway Clearing House, an industry standards body, recommended that GMT be
+# adopted at all stations as soon as the General Post Office permitted it.
+# The transition occurred on 12-01 for the L&NW, the Caledonian,
+# and presumably other railways; the January 1848 Bradshaw's lists many
+# railways as using GMT.  By 1855 the vast majority of public
+# clocks in Britain were set to GMT (though some, like the great clock
+# on Tom Tower at Christ Church, Oxford, were fitted with two minute hands,
+# one for local time and one for GMT).  The last major holdout was the legal
+# system, which stubbornly stuck to local time for many years, leading
+# to oddities like polls opening at 08:13 and closing at 16:13.
+# The legal system finally switched to GMT when the Statutes (Definition
+# of Time) Act took effect; it received the Royal Assent on 1880-08-02.
+#
+# In the tables below, we condense this complicated story into a single
+# transition date for London, namely 1847-12-01.  We don't know as much
+# about Dublin, so we use 1880-08-02, the legal transition time.
+
+# From Paul Eggert (2003-09-27):
+# Summer Time was first seriously proposed by William Willett (1857-1915),
+# a London builder and member of the Royal Astronomical Society
+# who circulated a pamphlet ``The Waste of Daylight'' (1907)
+# that proposed advancing clocks 20 minutes on each of four Sundays in April,
+# and retarding them by the same amount on four Sundays in September.
+# A bill was drafted in 1909 and introduced in Parliament several times,
+# but it met with ridicule and opposition, especially from farming interests.
+# Later editions of the pamphlet proposed one-hour summer time, and
+# it was eventually adopted as a wartime measure in 1916.
+# See: Summer Time Arrives Early, The Times (2000-05-18).
+# A monument to Willett was unveiled on 1927-05-21, in an open space in
+# a 45-acre wood near Chislehurst, Kent that was purchased by popular
+# subscription and open to the public.  On the south face of the monolith,
+# designed by G. W. Miller, is the...William Willett Memorial Sundial,
+# which is permanently set to Summer Time.
+
+# From Winston Churchill (1934-04-28):
+# It is one of the paradoxes of history that we should owe the boon of
+# summer time, which gives every year to the people of this country
+# between 160 and 170 hours more daylight leisure, to a war which
+# plunged Europe into darkness for four years, and shook the
+# foundations of civilization throughout the world.
+#	-- 
+#	"A Silent Toast to William Willett", Pictorial Weekly
+#	
+
+# From Paul Eggert (1996-09-03):
+# The OED Supplement says that the English originally said ``Daylight Saving''
+# when they were debating the adoption of DST in 1908; but by 1916 this
+# term appears only in quotes taken from DST's opponents, whereas the
+# proponents (who eventually won the argument) are quoted as using ``Summer''.
+
+# From Arthur David Olson (1989-01-19):
+#
+# A source at the British Information Office in New York avers that it's
+# known as "British" Summer Time in all parts of the United Kingdom.
+
+# Date: 4 Jan 89 08:57:25 GMT (Wed)
+# From: Jonathan Leffler
+# [British Summer Time] is fixed annually by Act of Parliament.
+# If you can predict what Parliament will do, you should be in
+# politics making a fortune, not computing.
+
+# From Chris Carrier (1996-06-14):
+# I remember reading in various wartime issues of the London Times the
+# acronym BDST for British Double Summer Time.  Look for the published
+# time of sunrise and sunset in The Times, when BDST was in effect, and
+# if you find a zone reference it will say, "All times B.D.S.T."
+
+# From Joseph S. Myers (1999-09-02):
+# ... some military cables (WO 219/4100 - this is a copy from the
+# main SHAEF archives held in the US National Archives, SHAEF/5252/8/516)
+# agree that the usage is BDST (this appears in a message dated 17 Feb 1945).
+
+# From Joseph S. Myers (2000-10-03):
+# On 18th April 1941, Sir Stephen Tallents of the BBC wrote to Sir
+# Alexander Maxwell of the Home Office asking whether there was any
+# official designation; the reply of the 21st was that there wasn't
+# but he couldn't think of anything better than the "Double British
+# Summer Time" that the BBC had been using informally.

+# http://student.cusu.cam.ac.uk/~jsm28/british-time/ho-19410421.png
+
+# From Sir Alexander Maxwell in the above-mentioned letter (1941-04-21):
+# [N]o official designation has as far as I know been adopted for the time
+# which is to be introduced in May....
+# I cannot think of anything better than "Double British Summer Time"
+# which could not be said to run counter to any official description.
+
+# From Paul Eggert (2000-10-02):
+# Howse writes (p 157) `DBST' too, but `BDST' seems to have been common
+# and follows the more usual convention of putting the location name first,
+# so we use `BDST'.
+
+# Peter Ilieve (1998-04-19) described at length
+# the history of summer time legislation in the United Kingdom.
+# Since 1998 Joseph S. Myers has been updating
+# and extending this list, which can be found in
+# http://student.cusu.cam.ac.uk/~jsm28/british-time/

+# exists, and the article can now be found at:
+# 
+# http://www.polyomino.org.uk/british-time/
+# 
+
+# From Joseph S. Myers (1998-01-06):
+#
+# The legal time in the UK outside of summer time is definitely GMT, not UTC;
+# see Lord Tanlaw's speech
+# 
+# (Lords Hansard 11 June 1997 columns 964 to 976)
+# .
+
+# From Paul Eggert (2006-03-22):
+#
+# For lack of other data, follow Shanks & Pottenger for Eire in 1940-1948.
+#
+# Given Ilieve and Myers's data, the following claims by Shanks & Pottenger
+# are incorrect:
+#     * Wales did not switch from GMT to daylight saving time until
+#	1921 Apr 3, when they began to conform with the rest of Great Britain.
+# Actually, Wales was identical after 1880.
+#     * Eire had two transitions on 1916 Oct 1.
+# It actually just had one transition.
+#     * Northern Ireland used single daylight saving time throughout WW II.
+# Actually, it conformed to Britain.
+#     * GB-Eire changed standard time to 1 hour ahead of GMT on 1968-02-18.
+# Actually, that date saw the usual switch to summer time.
+# Standard time was not changed until 1968-10-27 (the clocks didn't change).
+#
+# Here is another incorrect claim by Shanks & Pottenger:
+#     * Jersey, Guernsey, and the Isle of Man did not switch from GMT
+#	to daylight saving time until 1921 Apr 3, when they began to
+#	conform with Great Britain.
+# S.R.&O. 1916, No. 382 and HO 45/10811/312364 (quoted above) say otherwise.
+#
+# The following claim by Shanks & Pottenger is possible though doubtful;
+# we'll ignore it for now.
+#     * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00.
+#
+#
+# Whitman says Dublin Mean Time was -0:25:21, which is more precise than
+# Shanks & Pottenger.
+# Perhaps this was Dunsink Observatory Time, as Dunsink Observatory
+# (8 km NW of Dublin's center) seemingly was to Dublin as Greenwich was
+# to London.  For example:
+#
+#   "Timeball on the ballast office is down.  Dunsink time."
+#   -- James Joyce, Ulysses
+
+# From Joseph S. Myers (2005-01-26):
+# Irish laws are available online at www.irishstatutebook.ie.  These include
+# various relating to legal time, for example:
+#
+# ZZA13Y1923.html ZZA12Y1924.html ZZA8Y1925.html ZZSIV20PG1267.html

+#
+# [These are all relative to the root, e.g., the first is
+# .]
+#
+# (These are those I found, but there could be more.  In any case these
+# should allow various updates to the comments in the europe file to cover
+# the laws applicable in Ireland.)
+#
+# (Note that the time in the Republic of Ireland since 1968 has been defined
+# in terms of standard time being GMT+1 with a period of winter time when it
+# is GMT, rather than standard time being GMT with a period of summer time
+# being GMT+1.)
+
+# From Paul Eggert (1999-03-28):
+# Clive Feather (, 1997-03-31)
+# reports that Folkestone (Cheriton) Shuttle Terminal uses Concession Time
+# (CT), equivalent to French civil time.
+# Julian Hill (, 1998-09-30) reports that
+# trains between Dollands Moor (the freight facility next door)
+# and Frethun run in CT.
+# My admittedly uninformed guess is that the terminal has two authorities,
+# the French concession operators and the British civil authorities,
+# and that the time depends on who you're talking to.
+# If, say, the British police were called to the station for some reason,
+# I would expect the official police report to use GMT/BST and not CET/CEST.
+# This is a borderline case, but for now let's stick to GMT/BST.
+
+# From an anonymous contributor (1996-06-02):
+# The law governing time in Ireland is under Statutory Instrument SI 395/94,
+# which gives force to European Union 7th Council Directive # 94/21/EC.
+# Under this directive, the Minister for Justice in Ireland makes appropriate
+# regulations. I spoke this morning with the Secretary of the Department of
+# Justice (tel +353 1 678 9711) who confirmed to me that the correct name is
+# "Irish Summer Time", abbreviated to "IST".

+# Denmark, Faroe Islands, and Greenland
+
+# From Jesper Norgaard Welen (2005-04-26):
+# http://www.hum.aau.dk/~poe/tid/tine/DanskTid.htm says that the law
+# [introducing standard time] was in effect from 1894-01-01....
+# The page http://www.retsinfo.dk/_GETDOCI_/ACCN/A18930008330-REGL
+# confirms this, and states that the law was put forth 1893-03-29.
+#
+# The EU treaty with effect from 1973:
+# http://www.retsinfo.dk/_GETDOCI_/ACCN/A19722110030-REGL
+#
+# This provoked a new law from 1974 to make possible summer time changes
+# in subsequenet decrees with the law
+# http://www.retsinfo.dk/_GETDOCI_/ACCN/A19740022330-REGL
+#
+# It seems however that no decree was set forward until 1980.  I have
+# not found any decree, but in another related law, the effecting DST
+# changes are stated explicitly to be from 1980-04-06 at 02:00 to
+# 1980-09-28 at 02:00.  If this is true, this differs slightly from
+# the EU rule in that DST runs to 02:00, not 03:00.  We don't know
+# when Denmark began using the EU rule correctly, but we have only
+# confirmation of the 1980-time, so I presume it was correct in 1981:
+# The law is about the management of the extra hour, concerning
+# working hours reported and effect on obligatory-rest rules (which
+# was suspended on that night):
+# http://www.retsinfo.dk/_GETDOCI_/ACCN/C19801120554-REGL
+
+# From Jesper Norgaard Welen (2005-06-11):
+# The Herning Folkeblad (1980-09-26) reported that the night between
+# Saturday and Sunday the clock is set back from three to two.
+
+# From Paul Eggert (2005-06-11):
+# Hence the "02:00" of the 1980 law refers to standard time, not
+# wall-clock time, and so the EU rules were in effect in 1980.

+# From Paul Eggert (2004-10-31):
+# During World War II, Germany maintained secret manned weather stations in
+# East Greenland and Franz Josef Land, but we don't know their time zones.
+# My source for this is Wilhelm Dege's book mentioned under Svalbard.
+#
+# From Paul Eggert (2006-03-22):
+# Greenland joined the EU as part of Denmark, obtained home rule on 1979-05-01,
+# and left the EU on 1985-02-01.  It therefore should have been using EU
+# rules at least through 1984.  Shanks & Pottenger say Scoresbysund and Godthab
+# used C-Eur rules after 1980, but IATA SSIM (1991/1996) says they use EU
+# rules since at least 1991.  Assume EU rules since 1980.
+
+# From Gwillin Law (2001-06-06), citing
+#  (2001-03-15),
+# and with translations corrected by Steffen Thorsen:
+#
+# Greenland has four local times, and the relation to UTC
+# is according to the following time line:
+#
+# The military zone near Thule	UTC-4
+# Standard Greenland time	UTC-3
+# Scoresbysund			UTC-1
+# Danmarkshavn			UTC
+#
+# In the military area near Thule and in Danmarkshavn DST will not be
+# introduced.
+
+# From Rives McDow (2001-11-01):
+#
+# I correspond regularly with the Dansk Polarcenter, and wrote them at
+# the time to clarify the situation in Thule.  Unfortunately, I have
+# not heard back from them regarding my recent letter.  [But I have
+# info from earlier correspondence.]
+#
+# According to the center, a very small local time zone around Thule
+# Air Base keeps the time according to UTC-4, implementing daylight
+# savings using North America rules, changing the time at 02:00 local time....
+#
+# The east coast of Greenland north of the community of Scoresbysund
+# uses UTC in the same way as in Iceland, year round, with no dst.
+# There are just a few stations on this coast, including the
+# Danmarkshavn ICAO weather station mentioned in your September 29th
+# email.  The other stations are two sledge patrol stations in
+# Mestersvig and Daneborg, the air force base at Station Nord, and the
+# DPC research station at Zackenberg.
+#
+# Scoresbysund and two small villages nearby keep time UTC-1 and use
+# the same daylight savings time period as in West Greenland (Godthab).
+#
+# The rest of Greenland, including Godthab (this area, although it
+# includes central Greenland, is known as west Greenland), keeps time
+# UTC-3, with daylight savings methods according to European rules.
+#
+# It is common procedure to use UTC 0 in the wilderness of East and
+# North Greenland, because it is mainly Icelandic aircraft operators
+# maintaining traffic in these areas.  However, the official status of
+# this area is that it sticks with Godthab time.  This area might be
+# considered a dual time zone in some respects because of this.
+
+# From Rives McDow (2001-11-19):
+# I heard back from someone stationed at Thule; the time change took place
+# there at 2:00 AM.
+
+# From Paul Eggert (2006-03-22):
+# From 1997 on the CIA map shows Danmarkshavn on GMT;
+# the 1995 map as like Godthab.
+# For lack of better info, assume they were like Godthab before 1996.
+# startkart.no says Thule does not observe DST, but this is clearly an error,
+# so go with Shanks & Pottenger for Thule transitions until this year.
+# For 2007 on assume Thule will stay in sync with US DST rules.

+# From Peter Ilieve (1994-10-15):
+# A relative in Tallinn confirms the accuracy of the data for 1989 onwards
+# [through 1994] and gives the legal authority for it,
+# a regulation of the Government of Estonia, No. 111 of 1989....
+#
+# From Peter Ilieve (1996-10-28):
+# [IATA SSIM (1992/1996) claims that the Baltic republics switch at 01:00s,
+# but a relative confirms that Estonia still switches at 02:00s, writing:]
+# ``I do not [know] exactly but there are some little different
+# (confusing) rules for International Air and Railway Transport Schedules
+# conversion in Sunday connected with end of summer time in Estonia....
+# A discussion is running about the summer time efficiency and effect on
+# human physiology.  It seems that Estonia maybe will not change to
+# summer time next spring.''
+
+# From Peter Ilieve (1998-11-04), heavily edited:
+# 
+# The 1998-09-22 Estonian time law
+# 
+# refers to the Eighth Directive and cites the association agreement between
+# the EU and Estonia, ratified by the Estonian law (RT II 1995, 22--27, 120).
+#
+# I also asked [my relative] whether they use any standard abbreviation
+# for their standard and summer times. He says no, they use "suveaeg"
+# (summer time) and "talveaeg" (winter time).
+
+# From The Baltic Times (1999-09-09)
+# via Steffen Thorsen:
+# This year will mark the last time Estonia shifts to summer time,
+# a council of the ruling coalition announced Sept. 6....
+# But what this could mean for Estonia's chances of joining the European
+# Union are still unclear.  In 1994, the EU declared summer time compulsory
+# for all member states until 2001.  Brussels has yet to decide what to do
+# after that.
+
+# From Mart Oruaas (2000-01-29):
+# Regulation no. 301 (1999-10-12) obsoletes previous regulation
+# no. 206 (1998-09-22) and thus sticks Estonia to +02:00 GMT for all
+# the year round.  The regulation is effective 1999-11-01.
+
+# From Toomas Soome (2002-02-21):
+# The Estonian government has changed once again timezone politics.
+# Now we are using again EU rules.
+#
+# From Urmet Jaanes (2002-03-28):

+
+# From Janne Snabb (2010-0715):

+# I noticed that the Finland data is not accurate for years 1981 and 1982.

+# Iceland
+#
+# From Adam David (1993-11-06):
+# The name of the timezone in Iceland for system / mail / news purposes is GMT.
+#
+# (1993-12-05):
+# This material is paraphrased from the 1988 edition of the University of
+# Iceland Almanak.
+#
+# From January 1st, 1908 the whole of Iceland was standardised at 1 hour
+# behind GMT. Previously, local mean solar time was used in different parts
+# of Iceland, the almanak had been based on Reykjavik mean solar time which
+# was 1 hour and 28 minutes behind GMT.
+#
+# "first day of winter" referred to [below] means the first day of the 26 weeks
+# of winter, according to the old icelandic calendar that dates back to the
+# time the norsemen first settled Iceland.  The first day of winter is always
+# Saturday, but is not dependent on the Julian or Gregorian calendars.
+#
+# (1993-12-10):
+# I have a reference from the Oxford Icelandic-English dictionary for the
+# beginning of winter, which ties it to the ecclesiastical calendar (and thus
+# to the julian/gregorian calendar) over the period in question.
+#	the winter begins on the Saturday next before St. Luke's day
+#	(old style), or on St. Luke's day, if a Saturday.
+# St. Luke's day ought to be traceable from ecclesiastical sources. "old style"
+# might be a reference to the Julian calendar as opposed to Gregorian, or it
+# might mean something else (???).
+#
+# From Paul Eggert (2006-03-22):
+# The Iceland Almanak, Shanks & Pottenger, and Whitman disagree on many points.
+# We go with the Almanak, except for one claim from Shanks & Pottenger, namely
+# that Reykavik was 21W57 from 1837 to 1908, local mean time before that.

+# Latvia
+
+# From Liene Kanepe (1998-09-17):
+
+# I asked about this matter Scientific Secretary of the Institute of Astronomy
+# of The University of Latvia Dr. paed Mr. Ilgonis Vilks. I also searched the
+# correct data in juridical acts and I found some juridical documents about
+# changes in the counting of time in Latvia from 1981....
+#
+# Act No.35 of the Council of Ministers of Latvian SSR of 1981-01-22 ...
+# according to the Act No.925 of the Council of Ministers of USSR of 1980-10-24
+# ...: all year round the time of 2nd time zone + 1 hour, in addition turning
+# the hands of the clock 1 hour forward on 1 April at 00:00 (GMT 31 March 21:00)
+# and 1 hour backward on the 1 October at 00:00 (GMT 30 September 20:00).
+#
+# Act No.592 of the Council of Ministers of Latvian SSR of 1984-09-24 ...
+# according to the Act No.967 of the Council of Ministers of USSR of 1984-09-13
+# ...: all year round the time of 2nd time zone + 1 hour, in addition turning
+# the hands of the clock 1 hour forward on the last Sunday of March at 02:00
+# (GMT 23:00 on the previous day) and 1 hour backward on the last Sunday of
+# September at 03:00 (GMT 23:00 on the previous day).
+#
+# Act No.81 of the Council of Ministers of Latvian SSR of 1989-03-22 ...
+# according to the Act No.227 of the Council of Ministers of USSR of 1989-03-14
+# ...: since the last Sunday of March 1989 in Lithuanian SSR, Latvian SSR,
+# Estonian SSR and Kaliningrad region of Russian Federation all year round the
+# time of 2nd time zone (Moscow time minus one hour). On the territory of Latvia
+# transition to summer time is performed on the last Sunday of March at 02:00
+# (GMT 00:00), turning the hands of the clock 1 hour forward.  The end of
+# daylight saving time is performed on the last Sunday of September at 03:00
+# (GMT 00:00), turning the hands of the clock 1 hour backward. Exception is
+# 1989-03-26, when we must not turn the hands of the clock....
+#
+# The Regulations of the Cabinet of Ministers of the Republic of Latvia of
+# 1997-01-21 on transition to Summer time ... established the same order of
+# daylight savings time settings as in the States of the European Union.
+
+# From Andrei Ivanov (2000-03-06):
+# This year Latvia will not switch to Daylight Savings Time (as specified in
+# 
+# The Regulations of the Cabinet of Ministers of the Rep. of Latvia of
+# 29-Feb-2000 (#79), in Latvian for subscribers only).
+
+# 
+# From RFE/RL Newsline (2001-01-03), noted after a heads-up by Rives McDow:
+# 
+# The Latvian government on 2 January decided that the country will
+# institute daylight-saving time this spring, LETA reported.
+# Last February the three Baltic states decided not to turn back their
+# clocks one hour in the spring....
+# Minister of Economy Aigars Kalvitis noted that Latvia had too few
+# daylight hours and thus decided to comply with a draft European
+# Commission directive that provides for instituting daylight-saving
+# time in EU countries between 2002 and 2006. The Latvian government
+# urged Lithuania and Estonia to adopt a similar time policy, but it
+# appears that they will not do so....

+# Moldova
+
+# From Paul Eggert (2006-03-22):
+# A previous version of this database followed Shanks & Pottenger, who write
+# that Tiraspol switched to Moscow time on 1992-01-19 at 02:00.
+# However, this is most likely an error, as Moldova declared independence
+# on 1991-08-27 (the 1992-01-19 date is that of a Russian decree).
+# In early 1992 there was large-scale interethnic violence in the area
+# and it's possible that some Russophones continued to observe Moscow time.
+# But [two people] separately reported via
+# Jesper Norgaard that as of 2001-01-24 Tiraspol was like Chisinau.
+# The Tiraspol entry has therefore been removed for now.
+#
+# From Alexander Krivenyshev (2011-10-17):
+# Pridnestrovian Moldavian Republic (PMR, also known as
+# "Pridnestrovie") has abolished seasonal clock change (no transition
+# to the Winter Time).

+# http://www.allmoldova.com/moldova-news/1249064116.html
+# 
+#
+# The substance of this change (reinstatement of the Tiraspol entry)
+# is from a patch from Petr Machata (2011-10-17)
+#
+# From Tim Parenti (2011-10-19)
+# In addition, being situated at +4651+2938 would give Tiraspol
+# a pre-1880 LMT offset of 1:58:32.
+#
+# (which agrees with the earlier entry that had been removed)
+#
+# From Alexander Krivenyshev (2011-10-26)
+# NO need to divide Moldova into two timezones at this point.
+# As of today, Transnistria (Pridnestrovie)- Tiraspol reversed its own
+# decision to abolish DST this winter.
+# Following Moldova and neighboring Ukraine- Transnistria (Pridnestrovie)-
+# Tiraspol will go back to winter time on October 30, 2011.

+# Howse writes that the Netherlands' railways used GMT between 1892 and 1940,
+# but for other purposes the Netherlands used Amsterdam mean time.
+
+# However, Robert H. van Gent writes (2001-04-01):
+# Howse's statement is only correct up to 1909. From 1909-05-01 (00:00:00
+# Amsterdam mean time) onwards, the whole of the Netherlands (including
+# the Dutch railways) was required by law to observe Amsterdam mean time
+# (19 minutes 32.13 seconds ahead of GMT). This had already been the
+# common practice (except for the railways) for many decades but it was
+# not until 1909 when the Dutch government finally defined this by law.
+# On 1937-07-01 this was changed to 20 minutes (exactly) ahead of GMT and
+# was generally known as Dutch Time ("Nederlandse Tijd").
+#
+# (2001-04-08):
+# 1892-05-01 was the date when the Dutch railways were by law required to
+# observe GMT while the remainder of the Netherlands adhered to the common
+# practice of following Amsterdam mean time.
+#
+# (2001-04-09):
+# In 1835 the authorities of the province of North Holland requested the
+# municipal authorities of the towns and cities in the province to observe
+# Amsterdam mean time but I do not know in how many cases this request was
+# actually followed.
+#
+# From 1852 onwards the Dutch telegraph offices were by law required to
+# observe Amsterdam mean time. As the time signals from the observatory of
+# Leiden were also distributed by the telegraph system, I assume that most
+# places linked up with the telegraph (and railway) system automatically
+# adopted Amsterdam mean time.
+#
+# Although the early Dutch railway companies initially observed a variety
+# of times, most of them had adopted Amsterdam mean time by 1858 but it
+# was not until 1866 when they were all required by law to observe
+# Amsterdam mean time.

+# From Steffen Thorsen (2001-05-01):
+# Although I could not find it explicitly, it seems that Jan Mayen and
+# Svalbard have been using the same time as Norway at least since the
+# time they were declared as parts of Norway.  Svalbard was declared
+# as a part of Norway by law of 1925-07-17 no 11, section 4 and Jan
+# Mayen by law of 1930-02-27 no 2, section 2. (From
+# http://www.lovdata.no/all/nl-19250717-011.html and
+# http://www.lovdata.no/all/nl-19300227-002.html).  The law/regulation
+# for normal/standard time in Norway is from 1894-06-29 no 1 (came
+# into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a
+# part of this law since 1925/1930. (From
+# http://www.lovdata.no/all/nl-18940629-001.html ) I have not been
+# able to find if Jan Mayen used a different time zone (e.g. -0100)
+# before 1930. Jan Mayen has only been "inhabitated" since 1921 by
+# Norwegian meteorologists and maybe used the same time as Norway ever
+# since 1921.  Svalbard (Arctic/Longyearbyen) has been inhabited since
+# before 1895, and therefore probably changed the local time somewhere
+# between 1895 and 1925 (inclusive).
+
+# From Paul Eggert (2001-05-01):
+#
+# Actually, Jan Mayen was never occupied by Germany during World War II,
+# so it must have diverged from Oslo time during the war, as Oslo was
+# keeping Berlin time.
+#
+#  says that the meteorologists
+# burned down their station in 1940 and left the island, but returned in
+# 1941 with a small Norwegian garrison and continued operations despite
+# frequent air ttacks from Germans.  In 1943 the Americans established a
+# radiolocating station on the island, called "Atlantic City".  Possibly
+# the UTC offset changed during the war, but I think it unlikely that
+# Jan Mayen used German daylight-saving rules.
+#
+# Svalbard is more complicated, as it was raided in August 1941 by an
+# Allied party that evacuated the civilian population to England (says
+# ).  The Svalbard FAQ
+#  says that the Germans were
+# expelled on 1942-05-14.  However, small parties of Germans did return,
+# and according to Wilhelm Dege's book "War North of 80" (1954)
+# 
+# the German armed forces at the Svalbard weather station code-named
+# Haudegen did not surrender to the Allies until September 1945.
+#
+# All these events predate our cutoff date of 1970.  Unless we can
+# come up with more definitive info about the timekeeping during the
+# war years it's probably best just do...the following for now:

+# The law "Svensk forfattningssamling 1878, no 14" about standard time in 1879:
+# From the beginning of 1879 (that is 01-01 00:00) the time for all
+# places in the country is "the mean solar time for the meridian at
+# three degrees, or twelve minutes of time, to the west of the
+# meridian of the Observatory of Stockholm".  The law is dated 1878-05-31.
+#
+# The observatory at that time had the meridian 18 degrees 03' 30"
+# eastern longitude = 01:12:14 in time.  Less 12 minutes gives the
+# national standard time as 01:00:14 ahead of GMT....
+#
+# About the beginning of CET in Sweden. The lawtext ("Svensk
+# forfattningssamling 1899, no 44") states, that "from the beginning
+# of 1900... ... the same as the mean solar time for the meridian at
+# the distance of one hour of time from the meridian of the English
+# observatory at Greenwich, or at 12 minutes 14 seconds to the west
+# from the meridian of the Observatory of Stockholm". The law is dated
+# 1899-06-16.  In short: At 1900-01-01 00:00:00 the new standard time
+# in Sweden is 01:00:00 ahead of GMT.
+#
+# 1916: The lawtext ("Svensk forfattningssamling 1916, no 124") states
+# that "1916-05-15 is considered to begin one hour earlier". It is
+# pretty obvious that at 05-14 23:00 the clocks are set to 05-15 00:00....
+# Further the law says, that "1916-09-30 is considered to end one hour later".
+#
+# The laws regulating [DST] are available on the site of the Swedish
+# Parliament beginning with 1985 - the laws regulating 1980/1984 are

+#
+# (2001-05-13):
+#
+# I have now found a newspaper stating that at 1916-10-01 01:00
+# summertime the church-clocks etc were set back one hour to show
+# 1916-10-01 00:00 standard time.  The article also reports that some

+# I have researched the DST usage in Switzerland during the 1940ies.
+#
+# As I wrote in an earlier message, I suspected the current tzdata values
+# to be wrong. This is now verified.
+#
+# I have found copies of the original ruling by the Swiss Federal
+# government, in 'Eidgen[o]ssische Gesetzessammlung 1941 and 1942' (Swiss
+# federal law collection)...
+#
+# DST began on Monday 5 May 1941, 1:00 am by shifting the clocks to 2:00 am
+# DST ended on Monday 6 Oct 1941, 2:00 am by shifting the clocks to 1:00 am.
+#
+# DST began on Monday, 4 May 1942 at 01:00 am
+# DST ended on Monday, 5 Oct 1942 at 02:00 am
+#
+# There was no DST in 1940, I have checked the law collection carefully.
+# It is also indicated by the fact that the 1942 entry in the law
+# collection points back to 1941 as a reference, but no reference to any
+# other years are made.
+#
+# Newspaper articles I have read in the archives on 6 May 1941 reported
+# about the introduction of DST (Sommerzeit in German) during the previous
+# night as an absolute novelty, because this was the first time that such
+# a thing had happened in Switzerland.
+#
+# I have also checked 1916, because one book source (Gabriel, Traite de
+# l'heure dans le monde) claims that Switzerland had DST in 1916. This is
+# false, no official document could be found. Probably Gabriel got misled
+# by references to Germany, which introduced DST in 1916 for the first time.
+#
+# The tzdata rules for Switzerland must be changed to:
+# Rule  Swiss   1941    1942    -       May     Mon>=1  1:00    1:00    S
+# Rule  Swiss   1941    1942    -       Oct     Mon>=1  2:00    0       -
+#

+#
+# ...the European time rules are...standardized since 1981, when
+# most European coun[tr]ies started DST.  Before that year, only
+# a few countries (UK, France, Italy) had DST, each according
+# to own national rules.  In 1981, however, DST started on
+# 'Apr firstSun', and not on 'Mar lastSun' as in the following
+# years...
+# But also since 1981 there are some more national exceptions
+# than listed in 'europe': Switzerland, for example, joined DST
+# one year later, Denmark ended DST on 'Oct 1' instead of 'Sep
+# lastSun' in 1981---I don't know how they handle now.
+#
+# Finally, DST ist always from 'Apr 1' to 'Oct 1' in the
+# Soviet Union (as far as I know).

+# ...
+#
+# The information from Tom Hofmann is (as far as I know) not entirely correct.
+# After a request from chongo at amdahl I tried to retrieve all information
+# about DST in Europe.  I was able to find all from about 1969.
+#
+# ...standardization on DST in Europe started in about 1977 with switches on
+# first Sunday in April and last Sunday in September...
+# In 1981 UK joined Europe insofar that
+# the starting day for both shifted to last Sunday in March.  And from 1982
+# the whole of Europe used DST, with switch dates April 1 and October 1 in
+# the Sov[i]et Union.  In 1985 the SU reverted to standard Europe[a]n switch
+# dates...
+#
+# It should also be remembered that time-zones are not constants; e.g.
+# Portugal switched in 1976 from MET (or CET) to WET with DST...
+# Note also that though there were rules for switch dates not
+# all countries abided to these dates, and many individual deviations
+# occurred, though not since 1982 I believe.  Another note: it is always
+# assumed that DST is 1 hour ahead of normal time, this need not be the
+# case; at least in the Netherlands there have been times when DST was 2 hours
+# in advance of normal time.

+# The International Earth Rotation Service periodically uses leap seconds
+# to keep UTC to within 0.9 s of UT1
+# (which measures the true angular orientation of the earth in space); see
+# Terry J Quinn, The BIPM and the accurate measure of time,
+# Proc IEEE 79, 7 (July 1991), 894-905.
+# There were no leap seconds before 1972, because the official mechanism

+
+# The correction (+ or -) is made at the given time, so lines

+
+# United States
+
+# From Paul Eggert (1999-03-31):
+# Howse writes (pp 121-125) that time zones were invented by
+# Professor Charles Ferdinand Dowd (1825-1904),
+# Principal of Temple Grove Ladies' Seminary (Saratoga Springs, NY).
+# His pamphlet ``A System of National Time for Railroads'' (1870)
+# was the result of his proposals at the Convention of Railroad Trunk Lines
+# in New York City (1869-10).  His 1870 proposal was based on Washington, DC,
+# but in 1872-05 he moved the proposed origin to Greenwich.
+# His proposal was adopted by the railroads on 1883-11-18 at 12:00,
+# and the most of the country soon followed suit.
+
+# From Paul Eggert (2005-04-16):
+# That 1883 transition occurred at 12:00 new time, not at 12:00 old time.
+# See p 46 of David Prerau, Seize the daylight, Thunder's Mouth Press (2005).
+
+# From Paul Eggert (2006-03-22):
+# A good source for time zone historical data in the US is
+# Thomas G. Shanks, The American Atlas (5th edition),
+# San Diego: ACS Publications, Inc. (1991).
+# Make sure you have the errata sheet; the book is somewhat useless without it.
+# It is the source for most of the pre-1991 US entries below.
+
+# From Paul Eggert (2001-03-06):
+# Daylight Saving Time was first suggested as a joke by Benjamin Franklin
+# in his whimsical essay ``An Economical Project for Diminishing the Cost
+# of Light'' published in the Journal de Paris (1784-04-26).
+# Not everyone is happy with the results:
+#
+#	I don't really care how time is reckoned so long as there is some
+#	agreement about it, but I object to being told that I am saving
+#	daylight when my reason tells me that I am doing nothing of the kind.
+#	I even object to the implication that I am wasting something
+#	valuable if I stay in bed after the sun has risen.  As an admirer
+#	of moonlight I resent the bossy insistence of those who want to
+#	reduce my time for enjoying it.  At the back of the Daylight Saving
+#	scheme I detect the bony, blue-fingered hand of Puritanism, eager
+#	to push people into bed earlier, and get them up earlier, to make
+#	them healthy, wealthy and wise in spite of themselves.
+#
+#	-- Robertson Davies, The diary of Samuel Marchbanks,
+#	   Clarke, Irwin (1947), XIX, Sunday
+#
+# For more about the first ten years of DST in the United States, see
+# Robert Garland's 
+# Ten years of daylight saving from the Pittsburgh standpoint
+# (Carnegie Library of Pittsburgh, 1927).
+#
+# Shanks says that DST was called "War Time" in the US in 1918 and 1919.
+# However, DST was imposed by the Standard Time Act of 1918, which
+# was the first nationwide legal time standard, and apparently
+# time was just called "Standard Time" or "Daylight Saving Time".
+
+# From Arthur David Olson:
+# US Daylight Saving Time ended on the last Sunday of *October* in 1974.
+# See, for example, the front page of the Saturday, 1974-10-26
+# and Sunday, 1974-10-27 editions of the Washington Post.
+
+# From Arthur David Olson:
+# Before the Uniform Time Act of 1966 took effect in 1967, observance of
+# Daylight Saving Time in the US was by local option, except during wartime.
+
+# From Arthur David Olson (2000-09-25):
+# Last night I heard part of a rebroadcast of a 1945 Arch Oboler radio drama.
+# In the introduction, Oboler spoke of "Eastern Peace Time."
+# An AltaVista search turned up
+# :
+# "When the time is announced over the radio now, it is 'Eastern Peace
+# Time' instead of the old familiar 'Eastern War Time.'  Peace is wonderful."
+#  (August 1945) by way of confirmation.
+
+# From Joseph Gallant citing
+# George H. Douglas, _The Early Days of Radio Broadcasting_ (1987):
+# At 7 P.M. (Eastern War Time) [on 1945-08-14], the networks were set
+# to switch to London for Attlee's address, but the American people
+# never got to hear his speech live. According to one press account,
+# CBS' Bob Trout was first to announce the word of Japan's surrender,
+# but a few seconds later, NBC, ABC and Mutual also flashed the word
+# of surrender, all of whom interrupting the bells of Big Ben in
+# London which were to precede Mr. Attlee's speech.
+
+# From Paul Eggert (2003-02-09): It was Robert St John, not Bob Trout.  From
+# Myrna Oliver's obituary of St John on page B16 of today's Los Angeles Times:
+#
+# ... a war-weary U.S. clung to radios, awaiting word of Japan's surrender.
+# Any announcement from Asia would reach St. John's New York newsroom on a
+# wire service teletype machine, which had prescribed signals for major news.
+# Associated Press, for example, would ring five bells before spewing out
+# typed copy of an important story, and 10 bells for news "of transcendental
+# importance."
+#
+# On Aug. 14, stalling while talking steadily into the NBC networks' open
+# microphone, St. John heard five bells and waited only to hear a sixth bell,
+# before announcing confidently: "Ladies and gentlemen, World War II is over.
+# The Japanese have agreed to our surrender terms."
+#
+# He had scored a 20-second scoop on other broadcasters.
+
+# From Arthur David Olson (2005-08-22):
+# Paul has been careful to use the "US" rules only in those locations
+# that are part of the United States; this reflects the real scope of
+# U.S. government action.  So even though the "US" rules have changed
+# in the latest release, other countries won't be affected.

+# Here's database-relevant material from the 2001 "Alaska History" article:
+#
+# On September 20 [1979]...DOT...officials decreed that on April 27,
+# 1980, Juneau and other nearby communities would move to Yukon Time.
+# Sitka, Petersburg, Wrangell, and Ketchikan, however, would remain on
+# Pacific Time.
+#
+# ...on September 22, 1980, DOT Secretary Neil E. Goldschmidt rescinded the
+# Department's September 1979 decision. Juneau and other communities in
+# northern Southeast reverted to Pacific Time on October 26.
+#
+# On October 28 [1983]...the Metlakatla Indian Community Council voted
+# unanimously to keep the reservation on Pacific Time.
+#
+# According to DOT official Joanne Petrie, Indian reservations are not
+# bound to follow time zones imposed by neighboring jurisdictions.
+#
+# (The last is consistent with how the database now handles the Navajo
+# Nation.)
+
+# From Arthur David Olson (2011-02-09):

+# Community office (using contact information available at
+# 
+# http://www.commerce.state.ak.us/dca/commdb/CIS.cfm?Comm_Boro_name=Metlakatla
+# ).
+# It's shortly after 1:00 here on the east coast of the United States;
+# the staffer said it was shortly after 10:00 there. When I asked whether
+# that meant they were on Pacific time, they said no--they were on their
+# own time. I asked about daylight saving; they said it wasn't used. I
+# did not inquire about practices in the past.
+
+# From Arthur David Olson (2011-08-17):
+# For lack of better information, assume that Metlakatla's
+# abandonment of use of daylight saving resulted from the 1983 vote.

+# Wayne County, Kentucky
+#
+# From
+# 
+# Lake Cumberland LIFE
+#  (1999-01-29) via WKYM-101.7:
+# Clinton County has joined Wayne County in asking the DoT to change from
+# the Central to the Eastern time zone....  The Wayne County government made
+# the same request in December.  And while Russell County officials have not
+# taken action, the majority of respondents to a poll conducted there in
+# August indicated they would like to change to "fast time" also.
+# The three Lake Cumberland counties are the farthest east of any U.S.
+# location in the Central time zone.
+#
+# From Rich Wales (2000-08-29):
+# After prolonged debate, and despite continuing deep differences of opinion,
+# Wayne County (central Kentucky) is switching from Central (-0600) to Eastern
+# (-0500) time.  They won't "fall back" this year.  See Sara Shipley,
+# The difference an hour makes, Nando Times (2000-08-29 15:33 -0400).
+#
+# From Paul Eggert (2001-07-16):
+# The final rule was published in the
+# 
+# Federal Register 65, 160 (2000-08-17), page 50154-50158.

+#
+# From Paul Eggert (1999-03-31):
+# Shanks writes that Michigan started using standard time on 1885-09-18,
+# but Howse writes (pp 124-125, referring to Popular Astronomy, 1901-01)
+# that Detroit kept
+#
+#	local time until 1900 when the City Council decreed that clocks should
+#	be put back twenty-eight minutes to Central Standard Time.  Half the
+#	city obeyed, half refused.  After considerable debate, the decision
+#	was rescinded and the city reverted to Sun time.  A derisive offer to
+#	erect a sundial in front of the city hall was referred to the
+#	Committee on Sewers.  Then, in 1905, Central time was adopted
+#	by city vote.
+#
+# This story is too entertaining to be false, so go with Howse over Shanks.
+#
+# From Paul Eggert (2001-03-06):
+# Garland (1927) writes ``Cleveland and Detroit advanced their clocks
+# one hour in 1914.''  This change is not in Shanks.  We have no more

+# she quotes the Friday November 1/1918 edition of the Creston Review.
+# The quote includes these two statements:
+# 'Sunday the CPR went back to the old system of time...'
+# '... The daylight saving scheme was dropped all over Canada at the same time,'
+# These statements refer to a transition from daylight time to standard time
+# that occurred nationally on Sunday October 27/1918.  This transition was
+# also documented in the Saturday October 26/1918 edition of the Toronto Star.
+
+# In light of that evidence, we alter the date from the earlier believed
+# Oct 31, to Oct 27, 1918 (and Sunday is a more likely transition day
+# than Thursday) in all Canadian rulesets.

+# Ontario
+
+# From Paul Eggert (2006-07-09):
+# Shanks & Pottenger write that since 1970 most of Ontario has been like
+# Toronto.
+# Thunder Bay skipped DST in 1973.
+# Many smaller locales did not observe peacetime DST until 1974;
+# Nipigon (EST) and Rainy River (CST) are the largest that we know of.
+# Far west Ontario is like Winnipeg; far east Quebec is like Halifax.
+
+# From Mark Brader (2003-07-26):
+# [According to the Toronto Star] Orillia, Ontario, adopted DST
+# effective Saturday, 1912-06-22, 22:00; the article mentions that
+# Port Arthur (now part of Thunder Bay, Ontario) as well as Moose Jaw
+# have already done so.  In Orillia DST was to run until Saturday,
+# 1912-08-31 (no time mentioned), but it was met with considerable
+# hostility from certain segments of the public, and was revoked after
+# only two weeks -- I copied it as Saturday, 1912-07-07, 22:00, but
+# presumably that should be -07-06.  (1912-06-19, -07-12; also letters
+# earlier in June).
+#
+# Kenora, Ontario, was to abandon DST on 1914-06-01 (-05-21).
+
+# From Paul Eggert (1997-10-17):
+# Mark Brader writes that an article in the 1997-10-14 Toronto Star
+# says that Atikokan, Ontario currently does not observe DST,
+# but will vote on 11-10 whether to use EST/EDT.
+# He also writes that the
+# 
+# Ontario Time Act (1990, Chapter T.9)
+# 
+# says that Ontario east of 90W uses EST/EDT, and west of 90W uses CST/CDT.
+# Officially Atikokan is therefore on CST/CDT, and most likely this report
+# concerns a non-official time observed as a matter of local practice.
+#
+# From Paul Eggert (2000-10-02):
+# Matthews and Vincent (1998) write that Atikokan, Pickle Lake, and
+# New Osnaburgh observe CST all year, that Big Trout Lake observes
+# CST/CDT, and that Upsala and Shebandowan observe EST/EDT, all in
+# violation of the official Ontario rules.
+#
+# From Paul Eggert (2006-07-09):
+# Chris Walton (2006-07-06) mentioned an article by Stephanie MacLellan in the
+# 2005-07-21 Chronicle-Journal, which said:
+#
+#	The clocks in Atikokan stay set on standard time year-round.
+#	This means they spend about half the time on central time and
+#	the other half on eastern time.
+#
+#	For the most part, the system works, Mayor Dennis Brown said.
+#
+#	"The majority of businesses in Atikokan deal more with Eastern
+#	Canada, but there are some that deal with Western Canada," he
+#	said.  "I don't see any changes happening here."
+#
+# Walton also writes "Supposedly Pickle Lake and Mishkeegogamang
+# [New Osnaburgh] follow the same practice."
+
+# From Garry McKinnon (2006-07-14) via Chris Walton:
+# I chatted with a member of my board who has an outstanding memory
+# and a long history in Atikokan (and in the telecom industry) and he
+# can say for certain that Atikokan has been practicing the current
+# time keeping since 1952, at least.
+
+# From Paul Eggert (2006-07-17):
+# Shanks & Pottenger say that Atikokan has agreed with Rainy River
+# ever since standard time was introduced, but the information from
+# McKinnon sounds more authoritative.  For now, assume that Atikokan
+# switched to EST immediately after WWII era daylight saving time
+# ended.  This matches the old (less-populous) America/Coral_Harbour
+# entry since our cutoff date of 1970, so we can move
+# America/Coral_Harbour to the 'backward' file.

+# # Many smaller locales did not observe peacetime DST until 1974;
+# # Nipigon (EST) and Rainy River (CST) are the largest that we know of.
+#
+# In the (Toronto) Globe and Mail for Saturday, 1955-09-24, in the bottom
+# right corner of page 1, it says that Toronto will return to standard
+# time at 2 am Sunday morning (which agrees with the database), and that:
+#
+#     The one-hour setback will go into effect throughout most of Ontario,
+#     except in areas like Windsor which remains on standard time all year.
+#
+# Windsor is, of course, a lot larger than Nipigon.
+#
+# I only came across this incidentally.  I don't know if Windsor began
+# observing DST when Detroit did, or in 1974, or on some other date.
+#
+# By the way, the article continues by noting that:

+# for the other provinces only approximate:
+#
+# 	Province	Daylight saving time used
+# Prince Edward Island	Not used.
+# Nova Scotia		In Halifax only.
+# New Brunswick		In St. John only.
+# Quebec		In the following places:
+# 			Montreal	Lachine
+# 			Quebec		Mont-Royal
+# 			Levis		Iberville
+# 			St. Lambert	Cap de la Madeleine
+# 			Verdun		Loretteville
+# 			Westmount	Richmond
+# 			Outremont	St. Jerome
+# 			Longueuil	Greenfield Park
+# 			Arvida		Waterloo
+# 			Chambly-Canton	Beaulieu
+# 			Melbourne	La Tuque
+# 			St. Theophile	Buckingham
+# Ontario		Used generally in the cities and towns along
+# 			the southerly part of the province. Not
+# 			used in the northwesterlhy part.
+# Manitoba		Not used.
+# Saskatchewan		In Regina only.
+# Alberta		Not used.
+# British Columbia	Not used.
+#
+#   With some exceptions, the use of daylight saving may be said to be limited
+# to those cities and towns lying between Quebec city and Windsor, Ont.

+# Also, as far as I can tell, there was no order-in-council varying

+# Saskatchewan
+
+# From Mark Brader (2003-07-26):
+# The first actual adoption of DST in Canada was at the municipal
+# level.  As the [Toronto] Star put it (1912-06-07), "While people
+# elsewhere have long been talking of legislation to save daylight,
+# the city of Moose Jaw [Saskatchewan] has acted on its own hook."
+# DST in Moose Jaw began on Saturday, 1912-06-01 (no time mentioned:
+# presumably late evening, as below), and would run until "the end of
+# the summer".  The discrepancy between municipal time and railroad
+# time was noted.
+
+# From Paul Eggert (2003-07-27):
+# Willett (1914-03) notes that DST "has been in operation ... in the
+# City of Moose Jaw, Saskatchewan, for one year."
+
+# From Paul Eggert (2006-03-22):
+# Shanks & Pottenger say that since 1970 this region has mostly been as Regina.
+# Some western towns (e.g. Swift Current) switched from MST/MDT to CST in 1972.
+# Other western towns (e.g. Lloydminster) are like Edmonton.
+# Matthews and Vincent (1998) write that Denare Beach and Creighton
+# are like Winnipeg, in violation of Saskatchewan law.
+
+# From W. Jones (1992-11-06):
+# The. . .below is based on information I got from our law library, the
+# provincial archives, and the provincial Community Services department.
+# A precise history would require digging through newspaper archives, and
+# since you didn't say what you wanted, I didn't bother.
+#
+# Saskatchewan is split by a time zone meridian (105W) and over the years
+# the boundary became pretty ragged as communities near it reevaluated
+# their affiliations in one direction or the other.  In 1965 a provincial
+# referendum favoured legislating common time practices.
+#
+# On 15 April 1966 the Time Act (c. T-14, Revised Statutes of
+# Saskatchewan 1978) was proclaimed, and established that the eastern
+# part of Saskatchewan would use CST year round, that districts in
+# northwest Saskatchewan would by default follow CST but could opt to
+# follow Mountain Time rules (thus 1 hour difference in the winter and
+# zero in the summer), and that districts in southwest Saskatchewan would
+# by default follow MT but could opt to follow CST.
+#
+# It took a few years for the dust to settle (I know one story of a town
+# on one time zone having its school in another, such that a mom had to
+# serve her family lunch in two shifts), but presently it seems that only
+# a few towns on the border with Alberta (e.g. Lloydminster) follow MT
+# rules any more; all other districts appear to have used CST year round
+# since sometime in the 1960s.
+
+# From Chris Walton (2006-06-26):
+# The Saskatchewan time act which was last updated in 1996 is about 30 pages
+# long and rather painful to read.

+# British Columbia
+
+# From Paul Eggert (2006-03-22):
+# Shanks & Pottenger write that since 1970 most of this region has
+# been like Vancouver.
+# Dawson Creek uses MST.  Much of east BC is like Edmonton.
+# Matthews and Vincent (1998) write that Creston is like Dawson Creek.
+
+# It seems though that (re: Creston) is not entirely correct:
+
+# From Chris Walton (2011-12-01):
+# There are two areas within the Canadian province of British Columbia
+# that do not currently observe daylight saving:
+# a) The Creston Valley (includes the town of Creston and surrounding area)
+# b) The eastern half of the Peace River Regional District
+# (includes the cities of Dawson Creek and Fort St. John)
+
+# Earlier this year I stumbled across a detailed article about the time
+# keeping history of Creston; it was written by Tammy Hardwick who is the
+# manager of the Creston & District Museum. The article was written in May 2009.
+# 
+# http://www.ilovecreston.com/?p=articles&t=spec&ar=260
+# 
+# According to the article, Creston has not changed its clocks since June 1918.
+# i.e. Creston has been stuck on UTC-7 for 93 years.
+# Dawson Creek, on the other hand, changed its clocks as recently as April 1972.
+
+# Unfortunately the exact date for the time change in June 1918 remains
+# unknown and will be difficult to ascertain.  I e-mailed Tammy a few months
+# ago to ask if Sunday June 2 was a reasonable guess.  She said it was just
+# as plausible as any other date (in June).  She also said that after writing the
+# article she had discovered another time change in 1916; this is the subject
+# of another article which she wrote in October 2010.
+# 
+# http://www.creston.museum.bc.ca/index.php?module=comments&uop=view_comment&cm+id=56
+# 
+
+# Here is a summary of the three clock change events in Creston's history:
+# 1. 1884 or 1885: adoption of Mountain Standard Time (GMT-7)
+# Exact date unknown
+# 2. Oct 1916: switch to Pacific Standard Time (GMT-8)
+# Exact date in October unknown;  Sunday October 1 is a reasonable guess.
+# 3. June 1918: switch to Pacific Daylight Time (GMT-7)
+# Exact date in June unknown; Sunday June 2 is a reasonable guess.
+# note#1:
+# On Oct 27/1918 when daylight saving ended in the rest of Canada,
+# Creston did not change its clocks.
+# note#2:
+# During WWII when the Federal Government legislated a mandatory clock change,
+# Creston did not oblige.
+# note#3:
+# There is no guarantee that Creston will remain on Mountain Standard Time
+# (UTC-7) forever.
+# The subject was debated at least once this year by the town Council.
+# 
+# http://www.bclocalnews.com/kootenay_rockies/crestonvalleyadvance/news/116760809.html
+# 
+
+# During a period WWII, summer time (Daylight saying) was mandatory in Canada.
+# In Creston, that was handled by shifting the area to PST (-8:00) then applying
+# summer time to cause the offset to be -7:00, the same as it had been before
+# the change.  It can be argued that the timezone abbreviation during this
+# period should be PDT rather than MST, but that doesn't seem important enough
+# (to anyone) to further complicate the rules.
+
+# The transition dates (and times) are guesses.

+#	* 1967. Paragraph 28(34)(g) of the Interpretation Act, S.C. 1967-68,
+#	c. 7 defines Yukon standard time as UTC-9.  This is still valid;
+#	see Interpretation Act, R.S.C. 1985, c. I-21, s. 35(1).
+#	* C.O. 1973/214 switched Yukon to PST on 1973-10-28 00:00.
+#	* O.I.C. 1980/02 established DST.
+#	* O.I.C. 1987/056 changed DST to Apr firstSun 2:00 to Oct lastSun 2:00.
+# Shanks & Pottenger say Yukon's 1973-10-28 switch was at 2:00; go
+# with Englander.
+# From Chris Walton (2006-06-26):
+# Here is a link to the old daylight saving portion of the interpretation
+# act which was last updated in 1987:
+# http://www.gov.yk.ca/legislation/regs/oic1987_056.pdf
+
+# From Rives McDow (1999-09-04):
+# Nunavut ... moved ... to incorporate the whole territory into one time zone.
+# 
+# Nunavut moves to single time zone Oct. 31
+# 
+#
+# From Antoine Leca (1999-09-06):
+# We then need to create a new timezone for the Kitikmeot region of Nunavut
+# to differentiate it from the Yellowknife region.
+
+# From Paul Eggert (1999-09-20):
+# 
+# Basic Facts: The New Territory
+#  (1999) reports that Pangnirtung operates on eastern time,
+# and that Coral Harbour does not observe DST.  We don't know when
+# Pangnirtung switched to eastern time; we'll guess 1995.
+
+# From Rives McDow (1999-11-08):
+# On October 31, when the rest of Nunavut went to Central time,
+# Pangnirtung wobbled.  Here is the result of their wobble:
+#
+# The following businesses and organizations in Pangnirtung use Central Time:
+#
+#	First Air, Power Corp, Nunavut Construction, Health Center, RCMP,
+#	Eastern Arctic National Parks, A & D Specialist
+#
+# The following businesses and organizations in Pangnirtung use Eastern Time:
+#
+#	Hamlet office, All other businesses, Both schools, Airport operator
+#
+# This has made for an interesting situation there, which warranted the news.
+# No one there that I spoke with seems concerned, or has plans to
+# change the local methods of keeping time, as it evidently does not
+# really interfere with any activities or make things difficult locally.
+# They plan to celebrate New Year's turn-over twice, one hour apart,
+# so it appears that the situation will last at least that long.
+# The Nunavut Intergovernmental Affairs hopes that they will "come to
+# their senses", but the locals evidently don't see any problem with
+# the current state of affairs.
+
+# From Michaela Rodrigue, writing in the
+# 
+# Nunatsiaq News (1999-11-19):
+# Clyde River, Pangnirtung and Sanikiluaq now operate with two time zones,
+# central - or Nunavut time - for government offices, and eastern time
+# for municipal offices and schools....  Igloolik [was similar but then]
+# made the switch to central time on Saturday, Nov. 6.
+
+# From Paul Eggert (2000-10-02):
+# Matthews and Vincent (1998) say the following, but we lack histories
+# for these potential new Zones.
+#
+# The Canadian Forces station at Alert uses Eastern Time while the
+# handful of residents at the Eureka weather station [in the Central
+# zone] skip daylight savings.  Baffin Island, which is crossed by the
+# Central, Eastern and Atlantic Time zones only uses Eastern Time.
+# Gjoa Haven, Taloyoak and Pelly Bay all use Mountain instead of
+# Central Time and Southampton Island [in the Central zone] is not
+# required to use daylight savings.
+
+# From
+# 
+# Nunavut now has two time zones
+#  (2000-11-10):
+# The Nunavut government would allow its employees in Kugluktuk and
+# Cambridge Bay to operate on central time year-round, putting them
+# one hour behind the rest of Nunavut for six months during the winter.
+# At the end of October the two communities had rebelled against
+# Nunavut's unified time zone, refusing to shift to eastern time with
+# the rest of the territory for the winter.  Cambridge Bay remained on
+# central time, while Kugluktuk, even farther west, reverted to
+# mountain time, which they had used before the advent of Nunavut's
+# unified time zone in 1999.
+#
+# From Rives McDow (2001-01-20), quoting the Nunavut government:
+# The preceding decision came into effect at midnight, Saturday Nov 4, 2000.
+
+# From Paul Eggert (2000-12-04):
+# Let's just keep track of the official times for now.
+
+# From Rives McDow (2001-03-07):
+# The premier of Nunavut has issued a ministerial statement advising
+# that effective 2001-04-01, the territory of Nunavut will revert
+# back to three time zones (mountain, central, and eastern).  Of the
+# cities in Nunavut, Coral Harbor is the only one that I know of that
+# has said it will not observe dst, staying on EST year round.  I'm
+# checking for more info, and will get back to you if I come up with
+# more.
+# [Also see  (2001-03-09).]
+
+# From Gwillim Law (2005-05-21):
+# According to maps at
+# http://inms-ienm.nrc-cnrc.gc.ca/images/time_services/TZ01SWE.jpg
+# http://inms-ienm.nrc-cnrc.gc.ca/images/time_services/TZ01SSE.jpg
+# (both dated 2003), and
+# http://www.canadiangeographic.ca/Magazine/SO98/geomap.asp
+# (from a 1998 Canadian Geographic article), the de facto and de jure time
+# for Southampton Island (at the north end of Hudson Bay) is UTC-5 all year
+# round.  Using Google, it's easy to find other websites that confirm this.
+# I wasn't able to find how far back this time regimen goes, but since it
+# predates the creation of Nunavut, it probably goes back many years....
+# The Inuktitut name of Coral Harbour is Sallit, but it's rarely used.
+#
+# From Paul Eggert (2005-07-26):
+# For lack of better information, assume that Southampton Island observed
+# daylight saving only during wartime.
+
+# From Chris Walton (2007-03-01):
+# ... the community of Resolute (located on Cornwallis Island in
+# Nunavut) moved from Central Time to Eastern Time last November.
+# Basically the community did not change its clocks at the end of
+# daylight saving....
+# http://www.nnsl.com/frames/newspapers/2006-11/nov13_06none.html
+
+# From Chris Walton (2011-03-21):
+# Back in 2007 I initiated the creation of a new "zone file" for Resolute
+# Bay. Resolute Bay is a small community located about 900km north of
+# the Arctic Circle. The zone file was required because Resolute Bay had
+# decided to use UTC-5 instead of UTC-6 for the winter of 2006-2007.
+#
+# According to new information which I received last week, Resolute Bay
+# went back to using UTC-6 in the winter of 2007-2008...
+#
+# On March 11/2007 most of Canada went onto daylight saving. On March
+# 14/2007 I phoned the Resolute Bay hamlet office to do a "time check." I
+# talked to somebody that was both knowledgeable and helpful. I was able
+# to confirm that Resolute Bay was still operating on UTC-5. It was
+# explained to me that Resolute Bay had been on the Eastern Time zone
+# (EST) in the winter, and was now back on the Central Time zone (CDT).
+# i.e. the time zone had changed twice in the last year but the clocks
+# had not moved. The residents had to know which time zone they were in
+# so they could follow the correct TV schedule...
+#
+# On Nov 02/2008 most of Canada went onto standard time. On Nov 03/2008 I
+# phoned the Resolute Bay hamlet office...[D]ue to the challenging nature
+# of the phone call, I decided to seek out an alternate source of
+# information. I found an e-mail address for somebody by the name of
+# Stephanie Adams whose job was listed as "Inns North Support Officer for
+# Arctic Co-operatives." I was under the impression that Stephanie lived
+# and worked in Resolute Bay...
+#
+# On March 14/2011 I phoned the hamlet office again. I was told that
+# Resolute Bay had been using Central Standard Time over the winter of
+# 2010-2011 and that the clocks had therefore been moved one hour ahead
+# on March 13/2011. The person I talked to was aware that Resolute Bay
+# had previously experimented with Eastern Standard Time but he could not
+# tell me when the practice had stopped.
+#
+# On March 17/2011 I searched the Web to find an e-mail address of
+# somebody that might be able to tell me exactly when Resolute Bay went
+# off Eastern Standard Time. I stumbled on the name "Aziz Kheraj." Aziz
+# used to be the mayor of Resolute Bay and he apparently owns half the
+# businesses including "South Camp Inn." This website has some info on
+# Aziz:
+# 
+# http://www.uphere.ca/node/493
+# 
+#
+# I sent Aziz an e-mail asking when Resolute Bay had stopped using
+# Eastern Standard Time.
+#
+# Aziz responded quickly with this: "hi, The time was not changed for the
+# 1 year only, the following year, the community went back to the old way
+# of "spring ahead-fall behind" currently we are zulu plus 5 hrs and in
+# the winter Zulu plus 6 hrs"
+#
+# This of course conflicted with everything I had ascertained in November 2008.
+#
+# I sent Aziz a copy of my 2008 e-mail exchange with Stephanie. Aziz
+# responded with this: "Hi, Stephanie lives in Winnipeg. I live here, You
+# may want to check with the weather office in Resolute Bay or do a
+# search on the weather through Env. Canada. web site"
+#
+# If I had realized the Stephanie did not live in Resolute Bay I would
+# never have contacted her.  I now believe that all the information I
+# obtained in November 2008 should be ignored...
+# I apologize for reporting incorrect information in 2008.

+
+# From Paul Eggert (2001-03-05):
+# The Investigation and Analysis Service of the
+# Mexican Library of Congress (MLoC) has published a
+# 
+# history of Mexican local time (in Spanish)
+# .
+#
+# Here are the discrepancies between Shanks & Pottenger (S&P) and the MLoC.
+# (In all cases we go with the MLoC.)
+# S&P report that Baja was at -8:00 in 1922/1923.
+# S&P say the 1930 transition in Baja was 1930-11-16.
+# S&P report no DST during summer 1931.
+# S&P report a transition at 1932-03-30 23:00, not 1932-04-01.
+
+# From Gwillim Law (2001-02-20):
+# There are some other discrepancies between the Decrees page and the
+# tz database.  I think they can best be explained by supposing that
+# the researchers who prepared the Decrees page failed to find some of
+# the relevant documents.
+
+# From Alan Perry (1996-02-15):
+# A guy from our Mexico subsidiary finally found the Presidential Decree
+# outlining the timezone changes in Mexico.
+#
+# ------------- Begin Forwarded Message -------------
+#
+# I finally got my hands on the Official Presidential Decree that sets up the
+# rules for the DST changes. The rules are:
+#
+# 1. The country is divided in 3 timezones:
+#    - Baja California Norte (the Mexico/BajaNorte TZ)
+#    - Baja California Sur, Nayarit, Sinaloa and Sonora (the Mexico/BajaSur TZ)
+#    - The rest of the country (the Mexico/General TZ)
+#
+# 2. From the first Sunday in April at 2:00 AM to the last Sunday in October
+#    at 2:00 AM, the times in each zone are as follows:
+#    BajaNorte: GMT+7
+#    BajaSur:   GMT+6
+#    General:   GMT+5
+#
+# 3. The rest of the year, the times are as follows:
+#    BajaNorte: GMT+8
+#    BajaSur:   GMT+7
+#    General:   GMT+6
+#
+# The Decree was published in Mexico's Official Newspaper on January 4th.
+#
+# -------------- End Forwarded Message --------------
+# From Paul Eggert (1996-06-12):
+# For an English translation of the decree, see
+# 
+# ``Diario Oficial: Time Zone Changeover'' (1996-01-04).
+# 
+
+# From Rives McDow (1998-10-08):
+# The State of Quintana Roo has reverted back to central STD and DST times
+# (i.e. UTC -0600 and -0500 as of 1998-08-02).
+
+# From Rives McDow (2000-01-10):
+# Effective April 4, 1999 at 2:00 AM local time, Sonora changed to the time
+# zone 5 hours from the International Date Line, and will not observe daylight
+# savings time so as to stay on the same time zone as the southern part of
+# Arizona year round.
+
+# From Jesper Norgaard, translating
+#  (2001-01-17):
+# In Oaxaca, the 55.000 teachers from the Section 22 of the National
+# Syndicate of Education Workers, refuse to apply daylight saving each
+# year, so that the more than 10,000 schools work at normal hour the
+# whole year.
+
+# From Gwillim Law (2001-01-19):
+#  ... says
+# (translated):...
+# January 17, 2000 - The Energy Secretary, Ernesto Martens, announced
+# that Summer Time will be reduced from seven to five months, starting
+# this year....
+# 
+# [translated], says "summer time will ... take effect on the first Sunday
+# in May, and end on the last Sunday of September.
+
+# From Arthur David Olson (2001-01-25):
+# The 2001-01-24 traditional Washington Post contained the page one
+# story "Timely Issue Divides Mexicans."...
+# http://www.washingtonpost.com/wp-dyn/articles/A37383-2001Jan23.html
+# ... Mexico City Mayor Lopez Obrador "...is threatening to keep
+# Mexico City and its 20 million residents on a different time than
+# the rest of the country..." In particular, Lopez Obrador would abolish
+# observation of Daylight Saving Time.
+
+# 
+# Official statute published by the Energy Department
+#  (2001-02-01) shows Baja and Chihauhua as still using US DST rules,
+# and Sonora with no DST.  This was reported by Jesper Norgaard (2001-02-03).
+
+# From Paul Eggert (2001-03-03):
+#
+# 
+# James F. Smith writes in today's LA Times
+# 
+# * Sonora will continue to observe standard time.
+# * Last week Mexico City's mayor Andres Manuel Lopez Obrador decreed that
+#   the Federal District will not adopt DST.
+# * 4 of 16 district leaders announced they'll ignore the decree.
+# * The decree does not affect federal-controlled facilities including
+#   the airport, banks, hospitals, and schools.
+#
+# For now we'll assume that the Federal District will bow to federal rules.
+
+# From Jesper Norgaard (2001-04-01):
+# I found some references to the Mexican application of daylight
+# saving, which modifies what I had already sent you, stating earlier
+# that a number of northern Mexican states would go on daylight
+# saving. The modification reverts this to only cover Baja California
+# (Norte), while all other states (except Sonora, who has no daylight
+# saving all year) will follow the original decree of president
+# Vicente Fox, starting daylight saving May 6, 2001 and ending
+# September 30, 2001.
+# References: "Diario de Monterrey" 
+# Palabra  (2001-03-31)
+
+# From Reuters (2001-09-04):
+# Mexico's Supreme Court on Tuesday declared that daylight savings was
+# unconstitutional in Mexico City, creating the possibility the
+# capital will be in a different time zone from the rest of the nation
+# next year....  The Supreme Court's ruling takes effect at 2:00
+# a.m. (0800 GMT) on Sept. 30, when Mexico is scheduled to revert to
+# standard time. "This is so residents of the Federal District are not
+# subject to unexpected time changes," a statement from the court said.
+
+# From Jesper Norgaard Welen (2002-03-12):
+# ... consulting my local grocery store(!) and my coworkers, they all insisted
+# that a new decision had been made to reinstate US style DST in Mexico....
+# http://www.conae.gob.mx/ahorro/horaver2001_m1_2002.html (2002-02-20)
+# confirms this.  Sonora as usual is the only state where DST is not applied.

+# From Paul Eggert (2006-03-22):
+# Formerly there was an America/Ensenada zone, which differed from
+# America/Tijuana only in that it did not observe DST from 1976
+# through 1995.  This was as per Shanks (1999).  But Shanks & Pottenger say
+# Ensenada did not observe DST from 1948 through 1975.  Guy Harris reports
+# that the 1987 OAG says "Only Ensenada, Mexicale, San Felipe and
+# Tijuana observe DST," which agrees with Shanks & Pottenger but implies that
+# DST-observance was a town-by-town matter back then.  This concerns
+# data after 1970 so most likely there should be at least one Zone

+# the Orioles Radio Network, including affiliate WTOP in Washington, DC.
+# During the game, play-by-play announcer Jim Hunter noted that

+# Time today."  (The "two hour" remark referred to losing one hour of

+# , a Cuban information station, and heard

+

+# It seems that Cuba will start DST on Sunday, 2007-03-16...

+# Some more background information is posted here:

+# The article also says that Cuba has been observing DST since 1963,

+# Haiti
+# From Gwillim Law (2005-04-15):
+# Risto O. Nykanen wrote me that Haiti is now on DST.
+# I searched for confirmation, and I found a
+#  press release
+# on the Web page of the Haitian Consulate in Chicago (2005-03-31),
+# .  Translated from French, it says:
+#
+#  "The Prime Minister's Communication Office notifies the public in general
+#   and the press in particular that, following a decision of the Interior
+#   Ministry and the Territorial Collectivities [I suppose that means the
+#   provinces], Haiti will move to Eastern Daylight Time in the night from next
+#   Saturday the 2nd to Sunday the 3rd.
+#
+#  "Consequently, the Prime Minister's Communication Office wishes to inform
+#   the population that the country's clocks will be set forward one hour
+#   starting at midnight.  This provision will hold until the last Saturday in
+#   October 2005.
+#
+#  "Port-au-Prince, March 31, 2005"
+#
+# From Steffen Thorsen (2006-04-04):
+# I have been informed by users that Haiti observes DST this year like
+# last year, so the current "only" rule for 2005 might be changed to a
+# "max" rule or to last until 2006. (Who knows if they will observe DST
+# next year or if they will extend their DST like US/Canada next year).
+#
+# I have found this article about it (in French):
+# http://www.haitipressnetwork.com/news.cfm?articleID=7612
+#
+# The reason seems to be an energy crisis.
+
+# From Stephen Colebourne (2007-02-22):
+# Some IATA info: Haiti won't be having DST in 2007.
+
+# From Steffen Thorsen (2012-03-11):
+# According to several news sources, Haiti will observe DST this year,
+# apparently using the same start and end date as USA/Canada.
+# So this means they have already changed their time.

+# From Arthur David Olson (1989-04-05):
+# On 1989-04-05, the U. S. House of Representatives passed (238-154) a bill
+# establishing "Pacific Presidential Election Time"; it was not acted on
+# by the Senate or signed into law by the President.
+# You might want to change the "PE" (Presidential Election) below to
+# "Q" (Quadrennial) to maintain three-character zone abbreviations.
+# If you're really conservative, you might want to change it to "D".
+# Avoid "L" (Leap Year), which won't be true in 2100.
+
+# If Presidential Election Time is ever established, replace "XXXX" below
+# with the year the law takes effect and uncomment the "##" lines.

+# So much for footnotes about Saudi Arabia.
+# Apparent noon times below are for Riyadh; your mileage will vary.
+# Times were computed using formulas in the U.S. Naval Observatory's
+# Almanac for Computers 1987; the formulas "will give EqT to an accuracy of
+# [plus or minus two] seconds during the current year."
+#
+# Rounding to the nearest five seconds results in fewer than
+# 256 different "time types"--a limit that's faced because time types are
+# stored on disk as unsigned chars.

+# Apparent noon times below are for Riyadh; they're a bit off for other places.
+# Times were computed using formulas in the U.S. Naval Observatory's
+# Almanac for Computers 1988; the formulas "will give EqT to an accuracy of
+# [plus or minus two] seconds during the current year."
+#
+# Rounding to the nearest five seconds results in fewer than
+# 256 different "time types"--a limit that's faced because time types are
+# stored on disk as unsigned chars.

+# Apparent noon times below are for Riyadh; they're a bit off for other places.
+# Times were computed using a formula provided by the U. S. Naval Observatory:
+#	eqt = -105.8 * sin(l) + 596.2 * sin(2 * l) + 4.4 * sin(3 * l)
+#		-12.7 * sin(4 * l) - 429.0 * cos(l) - 2.1 * cos (2 * l)
+#		+ 19.3 * cos(3 * l);
+# where l is the "mean longitude of the Sun" given by
+#	l = 279.642 degrees + 0.985647 * d
+# and d is the interval in days from January 0, 0 hours Universal Time
+# (equaling the day of the year plus the fraction of a day from zero hours).
+# The accuracy of the formula is plus or minus three seconds.
+#
+# Rounding to the nearest five seconds results in fewer than
+# 256 different "time types"--a limit that's faced because time types are
+# stored on disk as unsigned chars.

+# This file is in the public domain, so clarified as of
+# 2009-05-17 by Arthur David Olson.
+
+# This data is by no means authoritative; if you think you know better,
+# go ahead and edit the file (and please send any changes to
+# tz@iana.org for general use in the future).
+
+# From Paul Eggert (2006-03-22):
+# A good source for time zone historical data outside the U.S. is
+# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
+# San Diego: ACS Publications, Inc. (2003).
+#
+# Gwillim Law writes that a good source
+# for recent time zone data is the International Air Transport
+# Association's Standard Schedules Information Manual (IATA SSIM),
+# published semiannually.  Law sent in several helpful summaries
+# of the IATA's data after 1990.
+#
+# Except where otherwise noted, Shanks & Pottenger is the source for
+# entries through 1990, and IATA SSIM is the source for entries afterwards.
+#
+# Earlier editions of these tables used the North American style (e.g. ARST and
+# ARDT for Argentine Standard and Daylight Time), but the following quote
+# suggests that it's better to use European style (e.g. ART and ARST).
+#	I suggest the use of _Summer time_ instead of the more cumbersome
+#	_daylight-saving time_.  _Summer time_ seems to be in general use
+#	in Europe and South America.
+#	-- E O Cutler, _New York Times_ (1937-02-14), quoted in
+#	H L Mencken, _The American Language: Supplement I_ (1960), p 466
+#
+# Earlier editions of these tables also used the North American style
+# for time zones in Brazil, but this was incorrect, as Brazilians say
+# "summer time".  Reinaldo Goulart, a Sao Paulo businessman active in
+# the railroad sector, writes (1999-07-06):
+#	The subject of time zones is currently a matter of discussion/debate in
+#	Brazil.  Let's say that "the Brasilia time" is considered the
+#	"official time" because Brasilia is the capital city.
+#	The other three time zones are called "Brasilia time "minus one" or
+#	"plus one" or "plus two".  As far as I know there is no such
+#	name/designation as "Eastern Time" or "Central Time".
+# So I invented the following (English-language) abbreviations for now.
+# Corrections are welcome!

+# From Hernan G. Otero (1995-06-26):

+# The change is supposed to take place Monday the 21.st at 0:00

+
+# From Jesper Norgaard Welen (2008-01-25):

+
+# From Mariano Absatz (2008-01-28):
+# I can confirm that the Province of San Luis (and so far only that

+# (that is, Monday 21st at 0:00 is the time the clocks were delayed back
+# 1 hour), and they intend to keep UTC-3 as their timezone all year round
+# (that is, unless they change their mind any minute now).
+#
+# So we'll have to add yet another city to 'southamerica' (I think San
+# Luis city is the mos populated city in the Province, so it'd be
+# America/Argentina/San_Luis... of course I can't remember if San Luis's
+# history of particular changes goes along with Mendoza or San Juan :-(
+# (I only remember not being able to collect hard facts about San Luis
+# back in 2004, when these provinces changed to UTC-4 for a few days, I

+
+# From Paul Eggert (2008-06-30):
+# Unless otherwise specified, data are from Shanks & Pottenger through 1992,

+# America/Cordoba split into 6 subregions during 1991/1992, one of which

+
+# From Mariano Absatz (2009-03-13):
+# Yesterday (with our usual 2-day notice) the Province of San Luis

+# 
+# http://www.lanacion.com.ar/nota.asp?nota_id=1107912
+# 
+#
+# The press release says:
+#  (...) anunció que el próximo domingo a las 00:00 los puntanos deberán
+# atrasar una hora sus relojes.
+#
+# A partir de entonces, San Luis establecerá el huso horario propio de

+# domingo de marzo y las 24:00 del segundo sábado de octubre.
+# Quick&dirty translation
+# (...) announced that next Sunday, at 00:00, Puntanos (the San Luis
+# inhabitants) will have to turn back one hour their clocks
+#
+# Since then, San Luis will establish its own Province timezone. Thus,
+# during 2009, this timezone change will run from 00:00 the third Sunday
+# in March until 24:00 of the second Saturday in October.
+
+# From Mariano Absatz (2009-10-16):
+# ...the Province of San Luis is a case in itself.
+#
+# The Law at
+# 
+# is ambiguous because establishes a calendar from the 2nd Sunday in
+# October at 0:00 thru the 2nd Saturday in March at 24:00 and the
+# complement of that starting on the 2nd Sunday of March at 0:00 and
+# ending on the 2nd Saturday of March at 24:00.
+#
+# This clearly breaks every time the 1st of March or October is a Sunday.
+#
+# IMHO, the "spirit of the Law" is to make the changes at 0:00 on the 2nd
+# Sunday of October and March.
+#
+# The problem is that the changes in the rest of the Provinces that did
+# change in 2007/2008, were made according to the Federal Law and Decrees
+# that did so on the 3rd Sunday of October and March.
+#
+# In fact, San Luis actually switched from UTC-4 to UTC-3 last Sunday
+# (October 11th) at 0:00.
+#
+# So I guess a new set of rules, besides "Arg", must be made and the last
+# America/Argentina/San_Luis entries should change to use these...
+#
+# I'm enclosing a patch that does what I say... regretfully, the San Luis
+# timezone must be called "WART/WARST" even when most of the time (like,
+# right now) WARST == ART... that is, since last Sunday, all the country
+# is using UTC-3, but in my patch, San Luis calls it "WARST" and the rest
+# of the country calls it "ART".
+# ...
+
+# From Alexander Krivenyshev (2010-04-09):
+# According to news reports from El Diario de la Republica Province San
+# Luis, Argentina (standard time UTC-04) will keep Daylight Saving Time

+
+# From Paul Eggert (1993-11-18):
+# The mayor of Rio recently attempted to change the time zone rules
+# just in his city, in order to leave more summer time for the tourist trade.
+# The rule change lasted only part of the day;
+# the federal government refused to follow the city's rules, and business
+# was in a chaos, so the mayor backed down that afternoon.
+
+# From IATA SSIM (1996-02):
+# _Only_ the following states in BR1 observe DST: Rio Grande do Sul (RS),
+# Santa Catarina (SC), Parana (PR), Sao Paulo (SP), Rio de Janeiro (RJ),
+# Espirito Santo (ES), Minas Gerais (MG), Bahia (BA), Goias (GO),
+# Distrito Federal (DF), Tocantins (TO), Sergipe [SE] and Alagoas [AL].
+# [The last three states are new to this issue of the IATA SSIM.]
+
+# From Gwillim Law (1996-10-07):
+# Geography, history (Tocantins was part of Goias until 1989), and other
+# sources of time zone information lead me to believe that AL, SE, and TO were
+# always in BR1, and so the only change was whether or not they observed DST....
+# The earliest issue of the SSIM I have is 2/91.  Each issue from then until
+# 9/95 says that DST is observed only in the ten states I quoted from 9/95,
+# along with Mato Grosso (MT) and Mato Grosso do Sul (MS), which are in BR2
+# (UTC-4)....  The other two time zones given for Brazil are BR3, which is
+# UTC-5, no DST, and applies only in the state of Acre (AC); and BR4, which is
+# UTC-2, and applies to Fernando de Noronha (formerly FN, but I believe it's
+# become part of the state of Pernambuco).  The boundary between BR1 and BR2
+# has never been clearly stated.  They've simply been called East and West.
+# However, some conclusions can be drawn from another IATA manual: the Airline
+# Coding Directory, which lists close to 400 airports in Brazil.  For each
+# airport it gives a time zone which is coded to the SSIM.  From that
+# information, I'm led to conclude that the states of Amapa (AP), Ceara (CE),
+# Maranhao (MA), Paraiba (PR), Pernambuco (PE), Piaui (PI), and Rio Grande do
+# Norte (RN), and the eastern part of Para (PA) are all in BR1 without DST.
+
+# From Marcos Tadeu (1998-09-27):
+# 
+# Brazilian official page
+# 
+
+# From Jesper Norgaard (2000-11-03):
+# [For an official list of which regions in Brazil use which time zones, see:]
+# http://pcdsh01.on.br/Fusbr.htm
+# http://pcdsh01.on.br/Fusbrhv.htm
+
+# From Celso Doria via David Madeo (2002-10-09):
+# The reason for the delay this year has to do with elections in Brazil.
+#
+# Unlike in the United States, elections in Brazil are 100% computerized and
+# the results are known almost immediately.  Yesterday, it was the first
+# round of the elections when 115 million Brazilians voted for President,
+# Governor, Senators, Federal Deputies, and State Deputies.  Nobody is
+# counting (or re-counting) votes anymore and we know there will be a second
+# round for the Presidency and also for some Governors.  The 2nd round will
+# take place on October 27th.
+#
+# The reason why the DST will only begin November 3rd is that the thousands
+# of electoral machines used cannot have their time changed, and since the
+# Constitution says the elections must begin at 8:00 AM and end at 5:00 PM,
+# the Government decided to postpone DST, instead of changing the Constitution
+# (maybe, for the next elections, it will be possible to change the clock)...
+
+# From Rodrigo Severo (2004-10-04):
+# It's just the biannual change made necessary by the much hyped, supposedly
+# modern Brazilian eletronic voting machines which, apparently, can't deal
+# with a time change between the first and the second rounds of the elections.
+
+# From Steffen Thorsen (2007-09-20):
+# Brazil will start DST on 2007-10-14 00:00 and end on 2008-02-17 00:00:
+# http://www.mme.gov.br/site/news/detail.do;jsessionid=BBA06811AFCAAC28F0285210913513DA?newsId=13975
+
+# From Paul Schulze (2008-06-24):
+# ...by law number 11.662 of April 24, 2008 (published in the "Diario
+# Oficial da Uniao"...) in Brazil there are changes in the timezones,
+# effective today (00:00am at June 24, 2008) as follows:
+#
+# a) The timezone UTC+5 is e[x]tinguished, with all the Acre state and the
+# part of the Amazonas state that had this timezone now being put to the
+# timezone UTC+4
+# b) The whole Para state now is put at timezone UTC+3, instead of just
+# part of it, as was before.
+#
+# This change follows a proposal of senator Tiao Viana of Acre state, that
+# proposed it due to concerns about open television channels displaying
+# programs inappropriate to youths in the states that had the timezone
+# UTC+5 too early in the night. In the occasion, some more corrections
+# were proposed, trying to unify the timezones of any given state. This
+# change modifies timezone rules defined in decree 2.784 of 18 June,
+# 1913.
+
+# From Rodrigo Severo (2008-06-24):
+# Just correcting the URL:
+# 
+# https://www.in.gov.br/imprensa/visualiza/index.jsp?jornal=do&secao=1&pagina=1&data=25/04/2008
+# 
+#
+# As a result of the above Decree I believe the America/Rio_Branco
+# timezone shall be modified from UTC-5 to UTC-4 and a new timezone shall
+# be created to represent the...west side of the Para State. I
+# suggest this new timezone be called Santarem as the most
+# important/populated city in the affected area.
+#
+# This new timezone would be the same as the Rio_Branco timezone up to
+# the 2008/06/24 change which would be to UTC-3 instead of UTC-4.
+
+# From Alex Krivenyshev (2008-06-24):
+# This is a quick reference page for New and Old Brazil Time Zones map.
+# 
+# http://www.worldtimezone.com/brazil-time-new-old.php
+# 
+#
+# - 4 time zones replaced by 3 time zones-eliminating time zone UTC- 05
+# (state Acre and the part of the Amazonas will be UTC/GMT- 04) - western
+# part of Par state is moving to one timezone UTC- 03 (from UTC -04).
+
+# From Paul Eggert (2002-10-10):
+# The official decrees referenced below are mostly taken from
+# 
+# Decretos sobre o Horario de Verao no Brasil
+# .
+
+# From Steffen Thorsen (2008-08-29):
+# As announced by the government and many newspapers in Brazil late
+# yesterday, Brazil will start DST on 2008-10-19 (need to change rule) and
+# it will end on 2009-02-15 (current rule for Brazil is fine). Based on
+# past years experience with the elections, there was a good chance that
+# the start was postponed to November, but it did not happen this year.

+# Chile
+
+# From Eduardo Krell (1995-10-19):
+# The law says to switch to DST at midnight [24:00] on the second SATURDAY
+# of October....  The law is the same for March and October.
+# (1998-09-29):
+# Because of the drought this year, the government decided to go into
+# DST earlier (saturday 9/26 at 24:00). This is a one-time change only ...
+# (unless there's another dry season next year, I guess).
+
+# From Julio I. Pacheco Troncoso (1999-03-18):
+# Because of the same drought, the government decided to end DST later,
+# on April 3, (one-time change).
+
+# From Oscar van Vlijmen (2006-10-08):
+# http://www.horaoficial.cl/cambio.htm
+
+# From Jesper Norgaard Welen (2006-10-08):
+# I think that there are some obvious mistakes in the suggested link
+# from Oscar van Vlijmen,... for instance entry 66 says that GMT-4
+# ended 1990-09-12 while entry 67 only begins GMT-3 at 1990-09-15
+# (they should have been 1990-09-15 and 1990-09-16 respectively), but
+# anyhow it clears up some doubts too.

+# From Paul Eggert (2006-12-27):
+# The following data for Chile and America/Santiago are from

+# & Pottenger, except with DST transitions after 1932 cloned from

+
+# From German Poo-Caaman~o (2008-03-03):

+
+# From Mauricio Parada (2012-02-22), translated by Glenn Eychaner (2012-02-23):
+# As stated in the website of the Chilean Energy Ministry
+# http://www.minenergia.cl/ministerio/noticias/generales/gobierno-anuncia-fechas-de-cambio-de.html
+# The Chilean Government has decided to postpone the entrance into winter time
+# (to leave DST) from March 11 2012 to April 28th 2012. The decision has not
+# been yet formalized but it will within the next days.
+# Quote from the website communication:
+#
+# 6. For the year 2012, the dates of entry into winter time will be as follows:
+# a. Saturday April 28, 2012, clocks should go back 60 minutes; that is, at
+# 23:59:59, instead of passing to 0:00, the time should be adjusted to be 23:00
+# of the same day.
+# b. Saturday, September 1, 2012, clocks should go forward 60 minutes; that is,
+# at 23:59:59, instead of passing to 0:00, the time should be adjusted to be
+# 01:00 on September 2.
+#
+# Note that...this is yet another "temporary" change that will be reevaluated
+# AGAIN in 2013.

+# Sunday 1 September.
+
+# From Rives McDow (2001-02-13):
+#
+# I have communicated several times with people there, and the last
+# time I had communications that was helpful was in 1998.  Here is
+# what was said then:
+#
+# "The general rule was that Stanley used daylight saving and the Camp
+# did not. However for various reasons many people in the Camp have
+# started to use daylight saving (known locally as 'Stanley Time')
+# There is no rule as to who uses daylight saving - it is a matter of
+# personal choice and so it is impossible to draw a map showing who
+# uses it and who does not. Any list would be out of date as soon as
+# it was produced. This year daylight saving ended on April 18/19th
+# and started again on September 12/13th.  I do not know what the rule
+# is, but can find out if you like.  We do not change at the same time
+# as UK or Chile."
+#
+# I did have in my notes that the rule was "Second Saturday in Sep at
+# 0:00 until third Saturday in Apr at 0:00".  I think that this does
+# not agree in some cases with Shanks; is this true?
+#
+# Also, there is no mention in the list that some areas in the
+# Falklands do not use DST.  I have found in my communications there
+# that these areas are on the western half of East Falkland and all of
+# West Falkland.  Stanley is the only place that consistently observes
+# DST.  Again, as in other places in the world, the farmers don't like
+# it.  West Falkland is almost entirely sheep farmers.
+#
+# I know one lady there that keeps a list of which farm keeps DST and
+# which doesn't each year.  She runs a shop in Stanley, and says that
+# the list changes each year.  She uses it to communicate to her
+# customers, catching them when they are home for lunch or dinner.
+
+# From Paul Eggert (2001-03-05):
+# For now, we'll just record the time in Stanley, since we have no
+# better info.
+
+# From Steffen Thorsen (2011-04-01):
+# The Falkland Islands will not turn back clocks this winter, but stay on
+# daylight saving time.
+#
+# One source:
+# 
+# http://www.falklandnews.com/public/story.cfm?get=5914&source=3
+# 
+#
+# We have gotten this confirmed by a clerk of the legislative assembly:
+# Normally the clocks revert to Local Mean Time (UTC/GMT -4 hours) on the
+# third Sunday of April at 0200hrs and advance to Summer Time (UTC/GMT -3
+# hours) on the first Sunday of September at 0200hrs.
+#
+# IMPORTANT NOTE: During 2011, on a trial basis, the Falkland Islands
+# will not revert to local mean time, but clocks will remain on Summer
+# time (UTC/GMT - 3 hours) throughout the whole of 2011.  Any long term
+# change to local time following the trial period will be notified.
+#
+# From Andrew Newman (2012-02-24)
+# A letter from Justin McPhee, Chief Executive,
+# Cable & Wireless Falkland Islands (dated 2012-02-22)
+# states...
+#   The current Atlantic/Stanley entry under South America expects the
+#   clocks to go back to standard Falklands Time (FKT) on the 15th April.
+#   The database entry states that in 2011 Stanley was staying on fixed
+#   summer time on a trial basis only.  FIG need to contact IANA and/or
+#   the maintainers of the database to inform them we're adopting
+#   the same policy this year and suggest recommendations for future years.
+#
+# For now we will assume permanent summer time for the Falklands
+# until advised differently (to apply for 2012 and beyond, after the 2011
+# experiment was apparently successful.)

+# No attempt is made to handle Newfoundland, since it cannot be expressed
+# using the System V "TZ" scheme (half-hour offset), or anything outside
+# North America (no support for non-standard DST start/end dates), nor
+# the changes in the DST rules in the US after 1976 (which occurred after
+# the old rules were written).
+#
+# If you need the old rules, uncomment ## lines.
+# Compile this *without* leap second correction for true conformance.

+# TZ zone descriptions
+#
+# From Paul Eggert (1996-08-05):
+#
+# This file contains a table with the following columns:
+# 1.  ISO 3166 2-character country code.  See the file `iso3166.tab'.
+# 2.  Latitude and longitude of the zone's principal location
+#     in ISO 6709 sign-degrees-minutes-seconds format,
+#     either +-DDMM+-DDDMM or +-DDMMSS+-DDDMMSS,
+#     first latitude (+ is north), then longitude (+ is east).
+# 3.  Zone name used in value of TZ environment variable.
+# 4.  Comments; present if and only if the country has multiple rows.
+#
+# Columns are separated by a single tab.
+# The table is sorted first by country, then an order within the country that
+# (1) makes some geographical sense, and
+# (2) puts the most populous zones first, where that does not contradict (1).
+#
+# Lines beginning with `#' are comments.
