# 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 <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 <LAW@encmail.encompass.com> 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.
# Corrections are welcome!

# 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.

# 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 Uighur 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 <eggert@twinsun.com> (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.

# We have no details, but we'll guess they didn't move the clocks back in fall.

# From Mathew Englander <mathew@io.org>, quoting AP (1996-10-23 13:05-04):
# Instead of putting back clocks at the end of October, Georgia

# 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.  Starting in 1999, the change to
# daylight savings time will still be on a Friday morning but from
# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
# will now also be on a Friday morning from 2 a.m. IDT to 1 a.m. IST.

# `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
#Rule	Japan	1948	only	-	May	Sun>=1	2:00	1:00	D

# 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.

# Mongolia

# 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):
# For now, we'll comment out the east zone (Choybalsan)
# and use Shanks's and the IATA's data for the daylight-saving rules.
# 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.

# Palestine

# 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-
# ------------+-----------+-----------+-----------+-----------
# 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.

# The rules for Egypt are stolen from the `africa' file.
