9# From Paul Eggert <eggert@twinsun.com> (1999-03-22):
10#
11# A good source for time zone historical data outside the U.S. is
12# Thomas G. Shanks, The International Atlas (5th edition),
13# San Diego: ACS Publications, Inc. (1999).
14#
15# Gwillim Law <Gwil_Law@bridge-point.com> writes that a good source
16# for recent time zone data is the International Air Transport
17# Association's Standard Schedules Information Manual (IATA SSIM),
18# published semiannually. Law sent in several helpful summaries
19# of the IATA's data after 1990.
20#
21# Except where otherwise noted, Shanks is the source for entries through 1990,
22# and IATA SSIM is the source for entries after 1990.
23#
24# Another source occasionally used is Edward W. Whitman, World Time Differences,
25# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
26# I found in the UCLA library.
27#
28# A reliable and entertaining source about time zones is
29# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
30#
31# I invented the abbreviations marked `*' in the following table;

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

164# From Guy Harris:
165# People's Republic of China. Yes, they really have only one time zone.
166
167# From Bob Devine (1988-01-28):
168# No they don't. See TIME mag, 1986-02-17 p.52. Even though
169# China is across 4 physical time zones, before Feb 1, 1986 only the
170# Peking (Bejing) time zone was recognized. Since that date, China
171# has two of 'em -- Peking's and Urumqi (named after the capital of
172# the Xinjiang Uighur Autonomous Region). I don't know about DST for it.
173#
174# . . .I just deleted the DST table and this editor makes it too
175# painful to suck in another copy.. So, here is what I have for
176# DST start/end dates for Peking's time zone (info from AP):

179# 1987 mid-April - ??

184
185# From Paul Eggert <eggert@twinsun.com> (1995-12-19):
186# Shanks writes that China has had a single time zone since 1980 May 1,
187# observing summer DST from 1986 through 1991; this contradicts Devine's
188# note about Time magazine, though apparently _something_ happened in 1986.
189# Go with Shanks for now. I made up names for the other pre-1980 time zones.

491# From Jonathan Lennox <lennox@cs.columbia.edu> (2000-06-12):
492# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
493# the U.S. edition) on the Iraqi Kurds contains a paragraph:
494# "The three northern provinces ... switched their clocks this spring and
495# are an hour ahead of Baghdad."
496#
497# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
498# In the past, some Kurdish nationalists, as a protest to the Iraqi
499# Government, did not adhere to daylight saving time. They referred
500# to daylight saving as Saddam time. But, as of today, the time zone
501# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
502#
503# So we'll ignore the Economist's claim.

527# From Ephraim Silverberg (2001-01-11):
528#
529# I coined "IST/IDT" circa 1988. Until then there were three
530# different abbreviations in use:
531#
532# JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
533# IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
534# EEST Eastern Europe Standard Time [used by almost everyone else]
535#
536# Since timezones should be called by country and not capital cities,
537# I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
538# EEST was equally unacceptable. Since "zonal" was not compatible with
539# any other timezone abbreviation, I felt that 'IST' was the way to go
540# and, indeed, it has received almost universal acceptance in timezone
541# settings in Israeli computers.
542#
543# In any case, I am happy to share timezone abbreviations with India,
544# high on my favorite-country list (and not only because my wife's
545# family is from India).

592
593# According to the Office of the Secretary General of the Ministry of
594# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
595# One thing is entrenched in law, however: that there must be at least 150
596# days of daylight savings time annually. From 1993-1998, the change to
597# daylight savings time was on a Friday morning from midnight IST to
598# 1 a.m IDT; up until 1998, the change back to standard time was on a
599# Saturday night from midnight daylight savings time to 11 p.m. standard
600# time. 1996 is an exception to this rule where the change back to standard
601# time took place on Sunday night instead of Saturday night to avoid
602# conflicts with the Jewish New Year. In 1999, the change to
603# daylight savings time was still on a Friday morning but from
604# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
605# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
606# 1999 only. In the year 2000, the change to daylight savings time was
607# similar to 1999, but although the change back will be on a Friday, it
608# will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
609# changes to/from will take place at 1 a.m. old time, but now there is no
610# rule as to what day of the week it will take place in as the start date
611# (except in 2003) is the night after the Passover Seder (i.e. the eve
612# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
613# (except in 2002) is three nights before Yom Kippur [Day of Atonement]
614# (the eve of the 7th of Tishrei in the lunar Hebrew calendar).

1020# From Amos Shapir <amos@nsof.co.il> (1998-02-15):
1021#
1022# From 1917 until 1948-05-15, all of Palestine, including the parts now
1023# known as the Gaza Strip and the West Bank, was under British rule.
1024# Therefore the rules given for Israel for that period, apply there too...
1025#
1026# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
1027# (except a short occupation by Israel from 1956-11 till 1957-03, but no
1028# time zone was affected then). It was never formally annexed to Egypt,
1029# though.
1030#
1031# The rest of Palestine was under Jordanian rule at that time, formally
1032# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
1033# the country's previous name of "the Hashemite Kingdom of the
1034# Trans-Jordan"). So the rules for Jordan for that time apply. Major
1035# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
1036# East Jerusalem.
1037#
1038# Both areas were occupied by Israel in June 1967, but not annexed (except
1039# for East Jerusalem). They were on Israel time since then; there might
1040# have been a Military Governor's order about time zones, but I'm not aware
1041# of any (such orders may have been issued semi-annually whenever summer
1042# time was in effect, but maybe the legal aspect of time was just neglected).
1043#
1044# The Palestinian Authority was established in 1993, and got hold of most
1045# towns in the West Bank and Gaza by 1995. I know that in order to
1046# demonstrate...independence, they have been switching to
1047# summer time and back on a different schedule than Israel's, but I don't
1048# know when this was started, or what algorithm is used (most likely the
1049# Jordanian one).
1050#
1051# To summarize, the table should probably look something like that:
1052#
1053# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
1054# ------------+-----------+-----------+-----------+-----------
1055# Israel | Zion | Zion | Zion | Zion
1056# West bank | Zion | Jordan | Zion | Jordan
1057# Gaza | Zion | Egypt | Zion | Jordan
1058#
1059# I guess more info may be available from the PA's web page (if/when they
1060# have one).
1061
1062# From Paul Eggert (1998-02-25):
1063# Shanks writes that Gaza did not observe DST until 1957, but we'll go
1064# with Shapir and assume that it observed DST from 1940 through 1947,
1065# and that it used Jordanian rules starting in 1996.
1066# We don't yet need a separate entry for the West Bank, since
1067# the only differences between it and Gaza that we know about
1068# occurred before our cutoff date of 1970.
1069# However, as we get more information, we may need to add entries
1070# for parts of the West Bank as they transitioned from Israel's rules
1071# to Palestine's rules. If you have more info about this, please
1072# send it to tz@elsie.nci.nih.gov for incorporation into future editions.

165# People's Republic of China. Yes, they really have only one time zone.
166
167# From Bob Devine (1988-01-28):
168# No they don't. See TIME mag, 1986-02-17 p.52. Even though
169# China is across 4 physical time zones, before Feb 1, 1986 only the
170# Peking (Bejing) time zone was recognized. Since that date, China
171# has two of 'em -- Peking's and Urumqi (named after the capital of
172# the Xinjiang Uighur Autonomous Region). I don't know about DST for it.
173#
174# . . .I just deleted the DST table and this editor makes it too
175# painful to suck in another copy.. So, here is what I have for
176# DST start/end dates for Peking's time zone (info from AP):

186# Shanks writes that China has had a single time zone since 1980 May 1,

188# note about Time magazine, though apparently _something_ happened in 1986.

492# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in

494# "The three northern provinces ... switched their clocks this spring and
495# are an hour ahead of Baghdad."
496#
497# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
498# In the past, some Kurdish nationalists, as a protest to the Iraqi
499# Government, did not adhere to daylight saving time. They referred
500# to daylight saving as Saddam time. But, as of today, the time zone
501# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.

525# Israel

527# From Ephraim Silverberg (2001-01-11):
528#
529# I coined "IST/IDT" circa 1988. Until then there were three
530# different abbreviations in use:
531#
532# JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
533# IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
534# EEST Eastern Europe Standard Time [used by almost everyone else]
535#
536# Since timezones should be called by country and not capital cities,
537# I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,

591# (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17 and 2000-07-25):
592
593# According to the Office of the Secretary General of the Ministry of
594# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
595# One thing is entrenched in law, however: that there must be at least 150
596# days of daylight savings time annually. From 1993-1998, the change to
597# daylight savings time was on a Friday morning from midnight IST to
598# 1 a.m IDT; up until 1998, the change back to standard time was on a
599# Saturday night from midnight daylight savings time to 11 p.m. standard
600# time. 1996 is an exception to this rule where the change back to standard
601# time took place on Sunday night instead of Saturday night to avoid
602# conflicts with the Jewish New Year. In 1999, the change to
603# daylight savings time was still on a Friday morning but from
604# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
605# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
606# 1999 only. In the year 2000, the change to daylight savings time was
607# similar to 1999, but although the change back will be on a Friday, it
608# will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
609# changes to/from will take place at 1 a.m. old time, but now there is no
610# rule as to what day of the week it will take place in as the start date
611# (except in 2003) is the night after the Passover Seder (i.e. the eve
612# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
613# (except in 2002) is three nights before Yom Kippur [Day of Atonement]
614# (the eve of the 7th of Tishrei in the lunar Hebrew calendar).

706# From Paul Eggert <eggert@twinsun.com> (1995-03-06):
707# Today's _Asahi Evening News_ (page 4) reports that Japan had
708# daylight saving between 1948 and 1951, but ``the system was discontinued
709# because the public believed it would lead to longer working hours.''
710# Shanks writes that daylight saving in Japan during those years was as follows:
711# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S

716# but the only locations using it were US military bases.
717# We go with Shanks and omit daylight saving in those years for Asia/Tokyo.
718
719# From Hideyuki Suzuki (1998-11-09):
720# 'Tokyo' usually stands for the former location of Tokyo Astronomical
721# Observatory: E 139 44' 40".90 (9h 18m 58s.727), N 35 39' 16".0.
722# This data is from 'Rika Nenpyou (Chronological Scientific Tables) 1996'
723# edited by National Astronomical Observatory of Japan....
724# JST (Japan Standard Time) has been used since 1888-01-01 00:00 (JST).
725# The law is enacted on 1886-07-07.
726
727# From Hideyuki Suzuki (1998-11-16):
728# The ordinance No. 51 (1886) established "standard time" in Japan,
729# which stands for the time on E 135 degree.
730# In the ordinance No. 167 (1895), "standard time" was renamed to "central
731# standard time". And the same ordinance also established "western standard
732# time", which stands for the time on E 120 degree.... But "western standard
733# time" was abolished in the ordinance No. 529 (1937). In the ordinance No.
734# 167, there is no mention regarding for what place western standard time is
735# standard....
736#
737# I wrote "ordinance" above, but I don't know how to translate.
738# In Japanese it's "chokurei", which means ordinance from emperor.
739
740# Shanks claims JST in use since 1896, and that a few places (e.g. Ishigaki)
741# use +0800; go with Suzuki. Guess that all ordinances took effect on Jan 1.

946# From Oscar van Vlijmen (1999-12-11):
947# <a href="http://www.mongoliatourism.gov.mn/general.htm">
948# General Information Mongolia
949# </a> (1999-09)
950# "Time: Mongolia has two time zones. Three westernmost provinces of
951# Bayan-Ulgii, Uvs, and Hovd are one hour earlier than the capital city, and
952# the rest of the country follows the Ulaanbaatar time, which is UTC/GMT plus
953# eight hours."
954
955# From Rives McDow (1999-12-13):
956# Mongolia discontinued the use of daylight savings time in 1999; 1998
957# being the last year it was implemented. The dates of implementation I am
958# unsure of, but most probably it was similar to Russia, except for the time
959# of implementation may have been different....
960# Some maps in the past have indicated that there was an additional time
961# zone in the eastern part of Mongolia, including the provinces of Dornod,
962# Suhbaatar, and possibly Khentij.
963
964# From Paul Eggert (1999-12-15):
965# For now, we'll comment out the east zone (Choybalsan)
966# and use Shanks's and the IATA's data for the daylight-saving rules.
967# Naming and spelling is tricky in Mongolia.
968# We'll use Hovd (also spelled Chovd and Khovd) to represent the west zone;
969# the capital of the Hovd province is sometimes called Hovd, sometimes Dund-Us,
970# and sometimes Jirgalanta (with variant spellings), but the name Hovd
971# is good enough for our purposes.

1020# From Amos Shapir <amos@nsof.co.il> (1998-02-15):
1021#
1022# From 1917 until 1948-05-15, all of Palestine, including the parts now
1023# known as the Gaza Strip and the West Bank, was under British rule.
1024# Therefore the rules given for Israel for that period, apply there too...
1025#
1026# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
1027# (except a short occupation by Israel from 1956-11 till 1957-03, but no
1028# time zone was affected then). It was never formally annexed to Egypt,
1029# though.
1030#
1031# The rest of Palestine was under Jordanian rule at that time, formally
1032# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
1033# the country's previous name of "the Hashemite Kingdom of the
1034# Trans-Jordan"). So the rules for Jordan for that time apply. Major
1035# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
1036# East Jerusalem.
1037#
1038# Both areas were occupied by Israel in June 1967, but not annexed (except
1039# for East Jerusalem). They were on Israel time since then; there might
1040# have been a Military Governor's order about time zones, but I'm not aware
1041# of any (such orders may have been issued semi-annually whenever summer
1042# time was in effect, but maybe the legal aspect of time was just neglected).
1043#
1044# The Palestinian Authority was established in 1993, and got hold of most
1045# towns in the West Bank and Gaza by 1995. I know that in order to
1046# demonstrate...independence, they have been switching to
1047# summer time and back on a different schedule than Israel's, but I don't
1048# know when this was started, or what algorithm is used (most likely the
1049# Jordanian one).
1050#
1051# To summarize, the table should probably look something like that:
1052#
1053# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
1054# ------------+-----------+-----------+-----------+-----------
1055# Israel | Zion | Zion | Zion | Zion
1056# West bank | Zion | Jordan | Zion | Jordan
1057# Gaza | Zion | Egypt | Zion | Jordan
1058#
1059# I guess more info may be available from the PA's web page (if/when they
1060# have one).
1061
1062# From Paul Eggert (1998-02-25):
1063# Shanks writes that Gaza did not observe DST until 1957, but we'll go
1064# with Shapir and assume that it observed DST from 1940 through 1947,
1065# and that it used Jordanian rules starting in 1996.
1066# We don't yet need a separate entry for the West Bank, since
1067# the only differences between it and Gaza that we know about
1068# occurred before our cutoff date of 1970.
1069# However, as we get more information, we may need to add entries
1070# for parts of the West Bank as they transitioned from Israel's rules
1071# to Palestine's rules. If you have more info about this, please
1072# send it to tz@elsie.nci.nih.gov for incorporation into future editions.
1073
1074# From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time,
1075# forwarded by Ephraim Silverberg:
1076#
1077# Despite the fact that Israel changed over to daylight savings time
1078# last week, the PLO Authority (PA) has decided not to turn its clocks
1079# one-hour forward at this time. As a sign of independence from Israeli rule,
1080# the PA has decided to implement DST in April.
1081
1082# From Paul Eggert (1999-09-20):
1083# Daoud Kuttab writes in

1085# Holiday havoc
1086# </a> (Jerusalem Post, 1999-04-22) that
1087# the Palestinian National Authority changed to DST on 1999-04-15.
1088# I vaguely recall that they switch back in October (sorry, forgot the source).
