# From Paul Eggert <eggert@twinsun.com> (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).
|
|

# Armenia
|

# 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
|
|
# <edd@AIC.NET> 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.

# People's Republic of China. Yes, they really have only one time zone.

# 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

# From Jonathan Lennox <lennox@cs.columbia.edu> (2000-06-12):
|
|
# 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).

|
|
|
# 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
|

# From Ephraim Silverberg (2002-07-07):
|
|
#
|
|
# The Israeli government today adopted a proposal by Minister of Interior
|
|
# Eli Yishai to shorten the period of Daylight Savings Time for the year
|
|
# 2002 (only -- the dates for 2003 and 2004 are, so far, unaffected).
|
|
#
|
|
# The proposed date to Daylight Savings Time is September 13, 2002 instead
|
|
# of the current date: October 7, 2002. The hour of changeover has not
|
|
# yet been decided.
|
|
#
|
|
# (2002-07-10):
|
|
# While today the Knesset passed the initial proposal to reduce DST by
|
|
# some three weeks, a new compromise is being worked out between
|
|
# Minister of Justice Meir Sheetrit and Minister of Interior Eli
|
|
# Yishai to revert to standard time for a period of 48-96 _hours_
|
|
# (sic) around the Yom Kippur fast day (September 15-16) and then go
|
|
# *back* to DST until the end of October. The details of the proposal
|
|
# have yet to be worked out, but the second and final readings of the
|
|
# bill have until July 24 to pass.
|
|
#
|
|
# (2002-07-25):
|
|
# Thanks go to Yitschak Goldberg from E&M for bringing this (Hebrew) article
|
|
# to my attention:
|
|
#
|
|
# http://www.ynet.co.il/articles/0,7340,L-2019315,00.html
|
|
#
|
|
# Hence, the proposal to shorten DST was withdrawn yesterday and the timezone
|
|
# files that have been in effect since July 2000 are still valid for all of
|
|
# 2002.
|
|
#
|
|
# Please note that the article mentions that the Shas MK's intend to
|
|
# bring up their amendment for future years (2003 and beyond). What this
|
|
# means exactly is anyone's guess since there are no set dates yet beyond
|
|
# 2004 and the end day set for 2003 and 2004 is already the 7th of Tishrei
|
|
# (i.e. before the fast of Yom Kippur). The only thing they may want to
|
|
# change is the start date of DST in 2003 from Mar.28.03 (24th of Adar II)
|
|
# to Apr.18.03 (16th of Nisan) so that the Passover Seder will take place
|
|
# during Standard Time. The start date for 2004 is already Nisan 16th.

# `9:00' and `JST' is from Guy Harris.

|
|
|
# From Paul Eggert <eggert@twinsun.com> (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.''
|
|
# Shanks writes that daylight saving in Japan during those years was as follows:

# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S

|
# but the only locations using it were US military bases.
|
|
# We go with Shanks and omit daylight saving in those years for Asia/Tokyo.
|
|
|
|
# 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.
|
|
|
|
# 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
|
|
# 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.

# "Time: Mongolia has two time zones. Three westernmost provinces of

# 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

# Naming and spelling is tricky in Mongolia.

# 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 Amos Shapir <amos@nsof.co.il> (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-

|
|
#
|
|
# 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.

|
#
|
|
# 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.
