# 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@elsie.nci.nih.gov for general use in the future).
# From Paul Eggert (1999-03-22):
#
# A good source for time zone historical data outside the U.S. is
# Thomas G. Shanks, The International Atlas (5th edition),
# San Diego: ACS Publications, Inc. (1999).
#
# 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 is the source for entries through 1990,
# and IATA SSIM is the source for entries after 1990.
#
# 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).
#
# I invented the abbreviations marked `*' in the following table;
# the rest are from earlier versions of this file, or from other sources.

# From Paul Eggert (1999-10-29):
# Shanks has Yerevan switching to 3:00 (with Russian DST) in spring 1991,
# then to 4:00 with no DST in fall 1995, then readopting Russian DST in 1997.
# Go with Shanks, even when he disagrees with others. Edgar Der-Danieliantz
# reported (1996-05-04) that Yerevan probably wouldn't use DST
# in 1996, though it did use DST in 1995. IATA SSIM (1991/1998) reports that
# Armenia switched from 3:00 to 4:00 in 1998 and observed DST after 1991,
# but started switching at 3:00s in 1998.

# China
# 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 - ??
# From U. S. Naval Observatory (1989-01-19):
# CHINA 8 H AHEAD OF UTC ALL OF CHINA, INCL TAIWAN
# CHINA 9 H AHEAD OF UTC APR 17 - SEP 10
# From Paul Eggert (1995-12-19):
# Shanks writes that China has had a single time zone since 1980 May 1,
# observing summer DST from 1986 through 1991; this contradicts Devine's
# note about Time magazine, though apparently _something_ happened in 1986.
# Go with Shanks for now. I made up names for the other pre-1980 time zones.

# Georgia
# 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.

# East Timor
# From Joao Carrascalao, brother of the former governor of East Timor, in
# <a href="http://etan.org/et99c/december/26-31/30ETMAY.htm">
# East Timor may be late for its millennium
# </a> (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.

#
# 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 (2005-04-05):
# Go with Shanks before September 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).

#
# 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

# 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).

# `9:00' and `JST' is from Guy Harris.
# From Paul Eggert (1995-03-06):
# Today's _Asahi Evening News_ (page 4) reports that Japan had
# daylight saving between 1948 and 1951, but ``the system was discontinued
# because the public believed it would lead to longer working hours.''
# From Mayumi Negishi in the 2005-08-10 Japan Times
# <http://www.japantimes.co.jp/cgi-bin/getarticle.pl5?nn20050810f2.htm>:
# 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
# dump the unpopular system in October 1951, less than a month after the San
# Francisco Peace Treaty was signed. (A government poll in 1951 showed 53%
# of the Japanese wanted to scrap daylight-saving time, as opposed to 30% who
# wanted to keep it.)
# Shanks writes that daylight saving in Japan during those years was as follows:

Rule Japan 1950 1951 - May Sun>=1 2:00 1:00 D
# but the only locations using it (for birth certificates, presumably, since
# Shanks's audience is astrologers) were US military bases. For now, assume
# that for most purposes daylight-saving time was observed; otherwise, what
# would have been the point of the 1951 poll?
# From Hideyuki Suzuki (1998-11-09):
# 'Tokyo' usually stands for the former location of Tokyo Astronomical
# Observatory: E 139 44' 40".90 (9h 18m 58s.727), N 35 39' 16".0.
# This data is from 'Rika Nenpyou (Chronological Scientific Tables) 1996'
# edited by National Astronomical Observatory of Japan....
# JST (Japan Standard Time) has been used since 1888-01-01 00:00 (JST).
# The law is enacted on 1886-07-07.

# 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
# standard time". And the same ordinance also established "western standard
# time", which stands for the time on E 120 degree.... But "western standard
# time" was abolished in the ordinance No. 529 (1937). In the ordinance No.
# 167, there is no mention regarding for what place western standard time is
# standard....
#
# I wrote "ordinance" above, but I don't know how to translate.
# In Japanese it's "chokurei", which means ordinance from emperor.
# Shanks claims JST in use since 1896, and that a few places (e.g. Ishigaki)
# use +0800; go with Suzuki. Guess that all ordinances took effect on Jan 1.

# Kazakhstan
# 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 (2001-10-18):
# 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, who has them always using RussiaAsia rules.
# Also go with the following claims of Shanks:
#
# - 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.
# <a href="http://www.kazsociety.org.uk/news/2005/03/30.htm">
# From Kazakhstan Embassy's News Bulletin #11 (2005-03-21):
# </a>
# 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
# de jure UTC+5 and UTC+6 respectively.

# Shanks says that Mongolia has three time zones, but usno1995 and the CIA map
# Standard Time Zones of the World (1997-01)
# both say that it has just one.
# From Oscar van Vlijmen (1999-12-11):
# <a href="http://www.mongoliatourism.gov.mn/general.htm">
# General Information Mongolia
# </a> (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
# <http://ubpost.mongolnews.mn/index.php?subaction=showcomments&id=1111634894&archive=&start_from=&ucat=1&>
# 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 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.
# From Paul Eggert (2002-03-15):
# Jesper Norgaard found this URL:
# http://www.pak.gov.pk/public/news/app/app06_dec.htm
# (dated 2001-12-06) which says that the Cabinet adopted a scheme "to
# 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
# and Sunday of April" phrase, if taken literally, means that the
# transition takes place at 00:00 on the first Sunday on or after 04-02.
# From Paul Eggert (2003-02-09):

# From Steffen Thorsen (2003-03-14):

#
# ISLAMABAD, March 6: Information and Media Development Minister Sheikh
# Rashid Ahmed on Thursday said the cabinet had reversed a previous
# decision to advance clocks by one hour in summer and put them back by
# one hour in winter with the aim of saving light hours and energy.

# The minister told a news conference that the experiment had rather

# 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 (1998-02-25):
# Shanks writes that Gaza did not observe DST until 1957, but we'll 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. If you have more info about this, please
# send it to tz@elsie.nci.nih.gov for incorporation into future editions.
# 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
# <a href="http://www.jpost.com/com/Archive/22.Apr.1999/Opinion/Article-2.html">
# Holiday havoc
# </a> (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.
# The rules for Egypt are stolen from the `africa' file.
