7# From Paul Eggert <eggert@twinsun.com> (1999-03-22):
8#
9# A good source for time zone historical data outside the U.S. is
10# Thomas G. Shanks, The International Atlas (5th edition),
11# San Diego: ACS Publications, Inc. (1999).
12#
13# Gwillim Law writes that a good source
14# for recent time zone data is the International Air Transport
15# Association's Standard Schedules Information Manual (IATA SSIM),
16# published semiannually. Law sent in several helpful summaries
17# of the IATA's data after 1990.
18#
19# Except where otherwise noted, Shanks is the source for entries through 1990,
20# and IATA SSIM is the source for entries after 1990.
21#
22# Another source occasionally used is Edward W. Whitman, World Time Differences,
23# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
24# I found in the UCLA library.
25#
26# A reliable and entertaining source about time zones is
27# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
28#
29# I invented the abbreviations marked `*' in the following table;

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

168# From Guy Harris:
169# People's Republic of China. Yes, they really have only one time zone.
170
171# From Bob Devine (1988-01-28):
172# No they don't. See TIME mag, 1986-02-17 p.52. Even though
173# China is across 4 physical time zones, before Feb 1, 1986 only the
174# Peking (Bejing) time zone was recognized. Since that date, China
175# has two of 'em -- Peking's and Urumqi (named after the capital of
176# the Xinjiang Uyghur Autonomous Region). I don't know about DST for it.
177#
178# . . .I just deleted the DST table and this editor makes it too
179# painful to suck in another copy.. So, here is what I have for
180# DST start/end dates for Peking's time zone (info from AP):

189# From Paul Eggert <eggert@twinsun.com> (1995-12-19):

191# observing summer DST from 1986 through 1991; this contradicts Devine's
192# note about Time magazine, though apparently _something_ happened in 1986.

397# <http://www.sumatera-inc.com/go_to_invest/about_indonesia.asp#standtime>
398# says that Indonesia's time zones changed on 1988-01-01. Looking at some
399# time zone maps, I think that must refer to Western Borneo (Kalimantan Barat
400# and Kalimantan Tengah) switching from UTC+8 to UTC+7.

435# From Roozbeh Pournader (2003-03-15):
436# This is an English translation of what I just found (originally in Persian).
437# The Gregorian dates in brackets are mine:
438#
439# Official Newspaper No. 13548-1370/6/25 [1991-09-16]

442# The Rule About Change of the Official Time of the Country
443#
444# The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14],
445# based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13]
446# of the Country's Organization for Official and Employment Affairs,
447# and referring to the law for equating the working hours of workers
448# and officers in the whole country dated 1359/4/23 [1980-07-14], and
449# for synchronizing the official times of the country, agreed that:
450#
451# The official time of the country will should move forward one hour
452# at the 24[:00] hours of the first day of Farvardin and should return
453# to its previous state at the 24[:00] hours of the 30th day of
454# Shahrivar.
455#
456# First Deputy to the President - Hassan Habibi
457#
458# From personal experience, that agrees with what has been followed
459# for at least the last 5 years. Before that, for a few years, the
460# date used was the first Thursday night of Farvardin and the last
461# Thursday night of Shahrivar, but I can't give exact dates....
462# I have also changed the abbreviations to what is considered correct
463# here in Iran, IRST for regular time and IRDT for daylight saving time.
464
465# From Paul Eggert (2003-03-15)
466# Go with Shanks before September 1991, and with Pournader thereafter.
467# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates.
468# The Persian calendar is based on the sun, and dates after around 2050
469# are approximate; stop after 2037 when 32-bit time_t's overflow.

531# From Jonathan Lennox <lennox@cs.columbia.edu> (2000-06-12):
532# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
533# the U.S. edition) on the Iraqi Kurds contains a paragraph:
534# "The three northern provinces ... switched their clocks this spring and
535# are an hour ahead of Baghdad."
536#
537# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
538# In the past, some Kurdish nationalists, as a protest to the Iraqi
539# Government, did not adhere to daylight saving time. They referred
540# to daylight saving as Saddam time. But, as of today, the time zone
541# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
542#
543# So we'll ignore the Economist's claim.

567# From Ephraim Silverberg (2001-01-11):
568#
569# I coined "IST/IDT" circa 1988. Until then there were three
570# different abbreviations in use:
571#
572# JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
573# IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
574# EEST Eastern Europe Standard Time [used by almost everyone else]
575#
576# Since timezones should be called by country and not capital cities,
577# I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
578# EEST was equally unacceptable. Since "zonal" was not compatible with
579# any other timezone abbreviation, I felt that 'IST' was the way to go
580# and, indeed, it has received almost universal acceptance in timezone
581# settings in Israeli computers.
582#
583# In any case, I am happy to share timezone abbreviations with India,
584# high on my favorite-country list (and not only because my wife's
585# family is from India).

632
633# According to the Office of the Secretary General of the Ministry of
634# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
635# One thing is entrenched in law, however: that there must be at least 150
636# days of daylight savings time annually. From 1993-1998, the change to
637# daylight savings time was on a Friday morning from midnight IST to
638# 1 a.m IDT; up until 1998, the change back to standard time was on a
639# Saturday night from midnight daylight savings time to 11 p.m. standard
640# time. 1996 is an exception to this rule where the change back to standard
641# time took place on Sunday night instead of Saturday night to avoid
642# conflicts with the Jewish New Year. In 1999, the change to
643# daylight savings time was still on a Friday morning but from
644# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
645# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
646# 1999 only. In the year 2000, the change to daylight savings time was
647# similar to 1999, but although the change back will be on a Friday, it
648# will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
649# changes to/from will take place at 1 a.m. old time, but now there is no
650# rule as to what day of the week it will take place in as the start date
651# (except in 2003) is the night after the Passover Seder (i.e. the eve
652# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
653# (except in 2002) is three nights before Yom Kippur [Day of Atonement]
654# (the eve of the 7th of Tishrei in the lunar Hebrew calendar).

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

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

168# From Guy Harris:
169# People's Republic of China. Yes, they really have only one time zone.

171# From Bob Devine (1988-01-28):
172# No they don't. See TIME mag, 1986-02-17 p.52. Even though
173# China is across 4 physical time zones, before Feb 1, 1986 only the
174# Peking (Bejing) time zone was recognized. Since that date, China
175# has two of 'em -- Peking's and Urumqi (named after the capital of
176# the Xinjiang Uyghur Autonomous Region). I don't know about DST for it.
177#
178# . . .I just deleted the DST table and this editor makes it too
179# painful to suck in another copy.. So, here is what I have for
180# DST start/end dates for Peking's time zone (info from AP):

444# The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14],
445# based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13]
446# of the Country's Organization for Official and Employment Affairs,
447# and referring to the law for equating the working hours of workers
448# and officers in the whole country dated 1359/4/23 [1980-07-14], and
449# for synchronizing the official times of the country, agreed that:
450#
451# The official time of the country will should move forward one hour
452# at the 24[:00] hours of the first day of Farvardin and should return
453# to its previous state at the 24[:00] hours of the 30th day of
454# Shahrivar.
455#
456# First Deputy to the President - Hassan Habibi
457#
458# From personal experience, that agrees with what has been followed
459# for at least the last 5 years. Before that, for a few years, the
460# date used was the first Thursday night of Farvardin and the last
461# Thursday night of Shahrivar, but I can't give exact dates....
462# I have also changed the abbreviations to what is considered correct

531# From Jonathan Lennox <lennox@cs.columbia.edu> (2000-06-12):
532# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
533# the U.S. edition) on the Iraqi Kurds contains a paragraph:
534# "The three northern provinces ... switched their clocks this spring and
535# are an hour ahead of Baghdad."
536#
537# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
538# In the past, some Kurdish nationalists, as a protest to the Iraqi
539# Government, did not adhere to daylight saving time. They referred
540# to daylight saving as Saddam time. But, as of today, the time zone
541# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
542#
543# So we'll ignore the Economist's claim.

566
567# From Ephraim Silverberg (2001-01-11):
568#
569# I coined "IST/IDT" circa 1988. Until then there were three
570# different abbreviations in use:
571#
572# JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
573# IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
574# EEST Eastern Europe Standard Time [used by almost everyone else]
575#
576# Since timezones should be called by country and not capital cities,
577# I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
578# EEST was equally unacceptable. Since "zonal" was not compatible with
579# any other timezone abbreviation, I felt that 'IST' was the way to go
580# and, indeed, it has received almost universal acceptance in timezone
581# settings in Israeli computers.
582#
583# In any case, I am happy to share timezone abbreviations with India,
584# high on my favorite-country list (and not only because my wife's
585# family is from India).

632
633# According to the Office of the Secretary General of the Ministry of
634# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
635# One thing is entrenched in law, however: that there must be at least 150
636# days of daylight savings time annually. From 1993-1998, the change to
637# daylight savings time was on a Friday morning from midnight IST to
638# 1 a.m IDT; up until 1998, the change back to standard time was on a
639# Saturday night from midnight daylight savings time to 11 p.m. standard
640# time. 1996 is an exception to this rule where the change back to standard
641# time took place on Sunday night instead of Saturday night to avoid
642# conflicts with the Jewish New Year. In 1999, the change to
643# daylight savings time was still on a Friday morning but from
644# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
645# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
646# 1999 only. In the year 2000, the change to daylight savings time was
647# similar to 1999, but although the change back will be on a Friday, it
648# will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
649# changes to/from will take place at 1 a.m. old time, but now there is no
650# rule as to what day of the week it will take place in as the start date
651# (except in 2003) is the night after the Passover Seder (i.e. the eve
652# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
653# (except in 2002) is three nights before Yom Kippur [Day of Atonement]

743# then-MK David Azulai [Shas]) fixing the dates for 2000-2004. Hence,
744# the dates for 2003 and 2004 remain unchanged....
|
744#
| 745#
|
745# The proposed date to Daylight Savings Time is September 13, 2002 instead
746# of the current date: October 7, 2002. The hour of changeover has not
747# yet been decided.
748#
749# (2002-07-10):
750# While today the Knesset passed the initial proposal to reduce DST by
751# some three weeks, a new compromise is being worked out between
752# Minister of Justice Meir Sheetrit and Minister of Interior Eli
753# Yishai to revert to standard time for a period of 48-96 _hours_
754# (sic) around the Yom Kippur fast day (September 15-16) and then go
755# *back* to DST until the end of October. The details of the proposal
756# have yet to be worked out, but the second and final readings of the
757# bill have until July 24 to pass.
758#
759# (2002-07-25):
760# Thanks go to Yitschak Goldberg from E&M for bringing this (Hebrew) article
761# to my attention:
762#
763# http://www.ynet.co.il/articles/0,7340,L-2019315,00.html
764#
765# Hence, the proposal to shorten DST was withdrawn yesterday and the timezone
766# files that have been in effect since July 2000 are still valid for all of
767# 2002.
768#
769# Please note that the article mentions that the Shas MK's intend to
770# bring up their amendment for future years (2003 and beyond). What this
771# means exactly is anyone's guess since there are no set dates yet beyond
772# 2004 and the end day set for 2003 and 2004 is already the 7th of Tishrei
773# (i.e. before the fast of Yom Kippur). The only thing they may want to
774# change is the start date of DST in 2003 from Mar.28.03 (24th of Adar II)
775# to Apr.18.03 (16th of Nisan) so that the Passover Seder will take place
776# during Standard Time. The start date for 2004 is already Nisan 16th.
| 746# As far as 2005 and beyond, no dates have been set. However, the
747# minister has mentioned that he wishes to propose to move Israel's
748# timezone in 2005 from GMT+2 to GMT+3 and upon that have DST during
749# the summer months (i.e. GMT+4). However, no legislation in this
750# direction is expected until the latter part of 2004 which is a long
751# time off in terms of Israeli politics.

785
786# From Paul Eggert <eggert@twinsun.com> (1995-03-06):
787# Today's _Asahi Evening News_ (page 4) reports that Japan had
788# daylight saving between 1948 and 1951, but ``the system was discontinued
789# because the public believed it would lead to longer working hours.''
790# Shanks writes that daylight saving in Japan during those years was as follows:
791# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S

797# We go with Shanks and omit daylight saving in those years for Asia/Tokyo.
798
799# From Hideyuki Suzuki (1998-11-09):
800# 'Tokyo' usually stands for the former location of Tokyo Astronomical
801# Observatory: E 139 44' 40".90 (9h 18m 58s.727), N 35 39' 16".0.
802# This data is from 'Rika Nenpyou (Chronological Scientific Tables) 1996'
803# edited by National Astronomical Observatory of Japan....
804# JST (Japan Standard Time) has been used since 1888-01-01 00:00 (JST).
805# The law is enacted on 1886-07-07.
806
807# From Hideyuki Suzuki (1998-11-16):
808# The ordinance No. 51 (1886) established "standard time" in Japan,
809# which stands for the time on E 135 degree.
810# In the ordinance No. 167 (1895), "standard time" was renamed to "central
811# standard time". And the same ordinance also established "western standard
812# time", which stands for the time on E 120 degree.... But "western standard
813# time" was abolished in the ordinance No. 529 (1937). In the ordinance No.
814# 167, there is no mention regarding for what place western standard time is
815# standard....
816#
817# I wrote "ordinance" above, but I don't know how to translate.
818# In Japanese it's "chokurei", which means ordinance from emperor.
819
820# Shanks claims JST in use since 1896, and that a few places (e.g. Ishigaki)

1195
1196# From Amos Shapir <amos@nsof.co.il> (1998-02-15):
1197#
1198# From 1917 until 1948-05-15, all of Palestine, including the parts now
1199# known as the Gaza Strip and the West Bank, was under British rule.
1200# Therefore the rules given for Israel for that period, apply there too...
1201#
1202# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
1203# (except a short occupation by Israel from 1956-11 till 1957-03, but no
1204# time zone was affected then). It was never formally annexed to Egypt,
1205# though.
1206#
1207# The rest of Palestine was under Jordanian rule at that time, formally
1208# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
1209# the country's previous name of "the Hashemite Kingdom of the
1210# Trans-Jordan"). So the rules for Jordan for that time apply. Major
1211# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
1212# East Jerusalem.
1213#
1214# Both areas were occupied by Israel in June 1967, but not annexed (except
1215# for East Jerusalem). They were on Israel time since then; there might
1216# have been a Military Governor's order about time zones, but I'm not aware
1217# of any (such orders may have been issued semi-annually whenever summer
1218# time was in effect, but maybe the legal aspect of time was just neglected).
1219#
1220# The Palestinian Authority was established in 1993, and got hold of most
1221# towns in the West Bank and Gaza by 1995. I know that in order to
1222# demonstrate...independence, they have been switching to
1223# summer time and back on a different schedule than Israel's, but I don't
1224# know when this was started, or what algorithm is used (most likely the
1225# Jordanian one).
1226#
1227# To summarize, the table should probably look something like that:
1228#
1229# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
1230# ------------+-----------+-----------+-----------+-----------
1231# Israel | Zion | Zion | Zion | Zion
1232# West bank | Zion | Jordan | Zion | Jordan
1233# Gaza | Zion | Egypt | Zion | Jordan
1234#
1235# I guess more info may be available from the PA's web page (if/when they
1236# have one).
1237
1238# From Paul Eggert (1998-02-25):
1239# Shanks writes that Gaza did not observe DST until 1957, but we'll go
1240# with Shapir and assume that it observed DST from 1940 through 1947,
1241# and that it used Jordanian rules starting in 1996.
1242# We don't yet need a separate entry for the West Bank, since
1243# the only differences between it and Gaza that we know about
1244# occurred before our cutoff date of 1970.
1245# However, as we get more information, we may need to add entries
1246# for parts of the West Bank as they transitioned from Israel's rules
1247# to Palestine's rules. If you have more info about this, please
1248# send it to tz@elsie.nci.nih.gov for incorporation into future editions.

1250# From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time,

1253# Despite the fact that Israel changed over to daylight savings time

1046# General Information Mongolia
1047# </a> (1999-09)
1048# "Time: Mongolia has two time zones. Three westernmost provinces of
1049# Bayan-Ulgii, Uvs, and Hovd are one hour earlier than the capital city, and
1050# the rest of the country follows the Ulaanbaatar time, which is UTC/GMT plus

1052
1053# From Rives McDow (1999-12-13):
1054# Mongolia discontinued the use of daylight savings time in 1999; 1998
1055# being the last year it was implemented. The dates of implementation I am
1056# unsure of, but most probably it was similar to Russia, except for the time
1057# of implementation may have been different....
1058# Some maps in the past have indicated that there was an additional time
1059# zone in the eastern part of Mongolia, including the provinces of Dornod,
1060# Suhbaatar, and possibly Khentij.
1061
1062# From Paul Eggert (1999-12-15):
1063# Naming and spelling is tricky in Mongolia.
1064# We'll use Hovd (also spelled Chovd and Khovd) to represent the west zone;
1065# the capital of the Hovd province is sometimes called Hovd, sometimes Dund-Us,

1067# is good enough for our purposes.

1121
1122# From Rives McDow (2002-03-13):
1123# I have been advised that Pakistan has decided to adopt dst on a
1124# TRIAL basis for one year, starting 00:01 local time on April 7, 2002
1125# and ending at 00:01 local time October 6, 2002. This is what I was
1126# told, but I believe that the actual time of change may be 00:00; the
1127# 00:01 was to make it clear which day it was on.

1129# From Paul Eggert (2002-03-15):
1130# Jesper Norgaard found this URL:
1131# http://www.pak.gov.pk/public/news/app/app06_dec.htm
1132# (dated 2001-12-06) which says that the Cabinet adopted a scheme "to
1133# advance the clocks by one hour on the night between the first
1134# Saturday and Sunday of April and revert to the original position on
1135# 15th October each year". This agrees with McDow's 04-07 at 00:00,
1136# but disagrees about the October transition, and makes it sound like
1137# it's not on a trial basis. Also, the "between the first Saturday
1138# and Sunday of April" phrase, if taken literally, means that the
1139# transition takes place at 00:00 on the first Sunday on or after 04-02.

1148#
1149# ISLAMABAD, March 6: Information and Media Development Minister Sheikh

1171# From Amos Shapir <amos@nsof.co.il> (1998-02-15):
1172#
1173# From 1917 until 1948-05-15, all of Palestine, including the parts now
1174# known as the Gaza Strip and the West Bank, was under British rule.
1175# Therefore the rules given for Israel for that period, apply there too...
1176#
1177# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
1178# (except a short occupation by Israel from 1956-11 till 1957-03, but no
1179# time zone was affected then). It was never formally annexed to Egypt,
1180# though.
1181#
1182# The rest of Palestine was under Jordanian rule at that time, formally
1183# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
1184# the country's previous name of "the Hashemite Kingdom of the
1185# Trans-Jordan"). So the rules for Jordan for that time apply. Major
1186# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
1187# East Jerusalem.
1188#
1189# Both areas were occupied by Israel in June 1967, but not annexed (except
1190# for East Jerusalem). They were on Israel time since then; there might
1191# have been a Military Governor's order about time zones, but I'm not aware
1192# of any (such orders may have been issued semi-annually whenever summer
1193# time was in effect, but maybe the legal aspect of time was just neglected).
1194#
1195# The Palestinian Authority was established in 1993, and got hold of most
1196# towns in the West Bank and Gaza by 1995. I know that in order to
1197# demonstrate...independence, they have been switching to
1198# summer time and back on a different schedule than Israel's, but I don't
1199# know when this was started, or what algorithm is used (most likely the
1200# Jordanian one).
1201#
1202# To summarize, the table should probably look something like that:
1203#
1204# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
1205# ------------+-----------+-----------+-----------+-----------
1206# Israel | Zion | Zion | Zion | Zion
1207# West bank | Zion | Jordan | Zion | Jordan
1208# Gaza | Zion | Egypt | Zion | Jordan
1209#
1210# I guess more info may be available from the PA's web page (if/when they
1211# have one).
1212
1213# From Paul Eggert (1998-02-25):
1214# Shanks writes that Gaza did not observe DST until 1957, but we'll go
1215# with Shapir and assume that it observed DST from 1940 through 1947,
1216# and that it used Jordanian rules starting in 1996.
1217# We don't yet need a separate entry for the West Bank, since
1218# the only differences between it and Gaza that we know about
1219# occurred before our cutoff date of 1970.
1220# However, as we get more information, we may need to add entries
1221# for parts of the West Bank as they transitioned from Israel's rules
1222# to Palestine's rules. If you have more info about this, please
1223# send it to tz@elsie.nci.nih.gov for incorporation into future editions.
1224
1225# From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time,
1226# forwarded by Ephraim Silverberg:
1227#
1228# Despite the fact that Israel changed over to daylight savings time
1229# last week, the PLO Authority (PA) has decided not to turn its clocks
1230# one-hour forward at this time. As a sign of independence from Israeli rule,
1231# the PA has decided to implement DST in April.

1233# From Paul Eggert (1999-09-20):

1236# Holiday havoc

1239# I vaguely recall that they switch back in October (sorry, forgot the source).
