7# From Paul Eggert <eggert@twinsun.com> (1996-11-22):
8#
9# A good source for time zone historical data outside the U.S. is
10# Thomas G. Shanks, The International Atlas (4th edition),
11# San Diego: ACS Publications, Inc. (1995).
12# Except where otherwise noted, it is the source for the data below.
13#
14# Gwillim Law <LAW@encmail.encompass.com> writes that a good source
15# for recent time zone data is the International Air Transport
16# Association's Standard Schedules Information Manual (IATA SSIM),
17# published semiannually. Law sent in several helpful summaries
18# of the IATA's data after 1990.
19#
20# Except where otherwise noted, Shanks is the source for entries through 1990,
21# and IATA SSIM is the source for entries after 1990.
22#
23# Another source occasionally used is Edward W. Whitman, World Time Differences,
24# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
25# I found in the UCLA library.
26#
27# A reliable and entertaining source about time zones is
28# Derek Howse, Greenwich time and the discovery of the longitude,
29# Oxford University Press (1980).
30#
31# I invented the abbreviations marked `*' in the following table;

80# Armenia
81# From Paul Eggert (1998-??-??):
82# Shanks has Yerevan switching to 3:00 (with Russian DST) in spring 1991,
83# but usno1995 has Armenia at 4:00 (with DST), and Edgar Der-Danieliantz
84# <edd@AIC.NET> reported (1996-05-04) that Yerevan probably wouldn't use DST
85# in 1996, though it did use DST in 1995. IATA SSIM (1991/1998) reports that
86# Armenia switched from 3:00 to 4:00 in 1998 and observed DST after 1991,
87# but started switching at 3:00s in 1998.
88# What a mess! We guess Yerevan DST stayed in sync with Moscow between 1990
89# and 1995, did not use DST in 1996, and started using DST again in 1997.

165
166# From Guy Harris:
167# People's Republic of China. Yes, they really have only one time zone.
168
169# From Bob Devine (1988-01-28):
170# No they don't. See TIME mag, 1986-02-17 p.52. Even though
171# China is across 4 physical time zones, before Feb 1, 1986 only the
172# Peking (Bejing) time zone was recognized. Since that date, China
173# has two of 'em -- Peking's and Urumqi (named after the capital of
174# the Xinjiang Uighur Autonomous Region). I don't know about DST for it.
175#
176# . . .I just deleted the DST table and this editor makes it too
177# painful to suck in another copy.. So, here is what I have for
178# DST start/end dates for Peking's time zone (info from AP):
179#
180# 1986 May 4 - Sept 14
181# 1987 mid-April - ??
182
183# From U. S. Naval Observatory (1989-01-19):

185# CHINA 9 H AHEAD OF UTC APR 17 - SEP 10
186
187# From Paul Eggert <eggert@twinsun.com> (1995-12-19):
188# Shanks writes that China has had a single time zone since 1980 May 1,
189# observing summer DST from 1986 through 1991; this contradicts Devine's
190# note about Time magazine, though apparently _something_ happened in 1986.
191# Go with Shanks for now. I made up names for the other pre-1980 time zones.

511# From Ephraim Silverberg <ephraim@cs.huji.ac.il>
512# (1997-03-04 and 1998-03-16):
513
514# According to the Office of the Secretary General of the Ministry of
515# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
516# Each year they decide anew what havoc to wreak on the country. However,
517# there is a "supposed" set of rules which is subject to change depending
518# on the party the Minister of Interior, the size of the coalition
519# government, the phase of the moon and the direction of the wind. Hence,
520# changes may need to be made on a semi-annual basis. One thing is entrenched
521# in law, however: that there must be at least 150 days of daylight savings
522# time annually. Ever since 1993, the change to daylight savings time is
523# on a Thursday night from midnight IST to 1 a.m IDT. The change back to
524# standard time is on a Saturday night from midnight daylight savings time
525# to 11 p.m. standard time. 1996 is an exception to this rule where the
526# change back to standard time took place on Sunday night instead of Saturday
527# night to avoid conflicts with the Jewish New Year.

838# Palestine
839
840# From Amos Shapir <amos@nsof.co.il> (1998-02-15):
841#
842# From 1917 until 1948-05-15, all of Palestine, including the parts now
843# known as the Gaza Strip and the West Bank, was under British rule.
844# Therefore the rules given for Israel for that period, apply there too...
845#
846# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
847# (except a short occupation by Israel from 1956-11 till 1957-03, but no
848# time zone was affected then). It was never formally annexed to Egypt,
849# though.
850#
851# The rest of Palestine was under Jordanian rule at that time, formally
852# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
853# the country's previous name of "the Hashemite Kingdom of the
854# Trans-Jordan"). So the rules for Jordan for that time apply. Major
855# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
856# East Jerusalem.
857#
858# Both areas were occupied by Israel in June 1967, but not annexed (except
859# for East Jerusalem). They were on Israel time since then; there might
860# have been a Military Governor's order about time zones, but I'm not aware
861# of any (such orders may have been issued semi-annually whenever summer
862# time was in effect, but maybe the legal aspect of time was just neglected).
863#
864# The Palestinian Authority was established in 1993, and got hold of most
865# towns in the West Bank and Gaza by 1995. I know that in order to
866# demonstrate...independence, they have been switching to
867# summer time and back on a different schedule than Israel's, but I don't
868# know when this was started, or what algorithm is used (most likely the
869# Jordanian one).
870#
871# To summarize, the table should probably look something like that:
872#
873# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
874# ------------+-----------+-----------+-----------+-----------
875# Israel | Zion | Zion | Zion | Zion
876# West bank | Zion | Jordan | Zion | Jordan
877# Gaza | Zion | Egypt | Zion | Jordan
878#
879# I guess more info may be available from the PA's web page (if/when they
880# have one).
881
882# From Paul Eggert (1998-02-25):
883# Shanks writes that Gaza did not observe DST until 1957, but we'll go
884# with Shapir and assume that it observed DST from 1940 through 1947,
885# and that it used Jordanian rules starting in 1996.
886# We don't yet need a separate entry for the West Bank, since
887# the only differences between it and Gaza that we know about
888# occurred before our cutoff date of 1970.
889# However, as we get more information, we may need to add entries
890# for parts of the West Bank as they transitioned from Israel's rules
891# to Palestine's rules. If you have more info about this, please
892# send it to tz@elsie.nci.nih.gov for incorporation into future editions.
893
894# From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time,
895# forwarded by Ephraim Silverberg:
896#
897# Despite the fact that Israel changed over to daylight savings time
898# last week, the PLO Authority (PA) has decided not to turn its clocks
899# one-hour forward at this time. As a sign of independence from Israeli rule,
900# the PA has decided to implement DST in April.

14# Gwillim Law <LAW@encmail.encompass.com> writes that a good source
15# for recent time zone data is the International Air Transport
16# Association's Standard Schedules Information Manual (IATA SSIM),
17# published semiannually. Law sent in several helpful summaries
18# of the IATA's data after 1990.
19#
20# Except where otherwise noted, Shanks is the source for entries through 1990,
21# and IATA SSIM is the source for entries after 1990.
22#
23# Another source occasionally used is Edward W. Whitman, World Time Differences,
24# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
25# I found in the UCLA library.
26#
27# A reliable and entertaining source about time zones is
28# Derek Howse, Greenwich time and the discovery of the longitude,
29# Oxford University Press (1980).

80# Armenia
81# From Paul Eggert (1998-??-??):
82# Shanks has Yerevan switching to 3:00 (with Russian DST) in spring 1991,
83# but usno1995 has Armenia at 4:00 (with DST), and Edgar Der-Danieliantz
84# <edd@AIC.NET> reported (1996-05-04) that Yerevan probably wouldn't use DST
85# in 1996, though it did use DST in 1995. IATA SSIM (1991/1998) reports that
86# Armenia switched from 3:00 to 4:00 in 1998 and observed DST after 1991,
87# but started switching at 3:00s in 1998.
88# What a mess! We guess Yerevan DST stayed in sync with Moscow between 1990
89# and 1995, did not use DST in 1996, and started using DST again in 1997.

165
166# From Guy Harris:
167# People's Republic of China. Yes, they really have only one time zone.
168
169# From Bob Devine (1988-01-28):
170# No they don't. See TIME mag, 1986-02-17 p.52. Even though
171# China is across 4 physical time zones, before Feb 1, 1986 only the
172# Peking (Bejing) time zone was recognized. Since that date, China
173# has two of 'em -- Peking's and Urumqi (named after the capital of
174# the Xinjiang Uighur Autonomous Region). I don't know about DST for it.
175#
176# . . .I just deleted the DST table and this editor makes it too
177# painful to suck in another copy.. So, here is what I have for
178# DST start/end dates for Peking's time zone (info from AP):
179#
180# 1986 May 4 - Sept 14
181# 1987 mid-April - ??
182
183# From U. S. Naval Observatory (1989-01-19):

185# CHINA 9 H AHEAD OF UTC APR 17 - SEP 10
186
187# From Paul Eggert <eggert@twinsun.com> (1995-12-19):
188# Shanks writes that China has had a single time zone since 1980 May 1,
189# observing summer DST from 1986 through 1991; this contradicts Devine's
190# note about Time magazine, though apparently _something_ happened in 1986.
191# Go with Shanks for now. I made up names for the other pre-1980 time zones.

511# From Ephraim Silverberg <ephraim@cs.huji.ac.il>
512# (1997-03-04 and 1998-03-16):
513
514# According to the Office of the Secretary General of the Ministry of
515# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
516# Each year they decide anew what havoc to wreak on the country. However,
517# there is a "supposed" set of rules which is subject to change depending
518# on the party the Minister of Interior, the size of the coalition
519# government, the phase of the moon and the direction of the wind. Hence,
520# changes may need to be made on a semi-annual basis. One thing is entrenched
521# in law, however: that there must be at least 150 days of daylight savings
522# time annually. Ever since 1993, the change to daylight savings time is
523# on a Thursday night from midnight IST to 1 a.m IDT. The change back to
524# standard time is on a Saturday night from midnight daylight savings time
525# to 11 p.m. standard time. 1996 is an exception to this rule where the
526# change back to standard time took place on Sunday night instead of Saturday
527# night to avoid conflicts with the Jewish New Year.

838# Palestine
839
840# From Amos Shapir <amos@nsof.co.il> (1998-02-15):
841#
842# From 1917 until 1948-05-15, all of Palestine, including the parts now
843# known as the Gaza Strip and the West Bank, was under British rule.
844# Therefore the rules given for Israel for that period, apply there too...
845#
846# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
847# (except a short occupation by Israel from 1956-11 till 1957-03, but no
848# time zone was affected then). It was never formally annexed to Egypt,
849# though.
850#
851# The rest of Palestine was under Jordanian rule at that time, formally
852# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
853# the country's previous name of "the Hashemite Kingdom of the
854# Trans-Jordan"). So the rules for Jordan for that time apply. Major
855# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
856# East Jerusalem.
857#
858# Both areas were occupied by Israel in June 1967, but not annexed (except
859# for East Jerusalem). They were on Israel time since then; there might
860# have been a Military Governor's order about time zones, but I'm not aware
861# of any (such orders may have been issued semi-annually whenever summer
862# time was in effect, but maybe the legal aspect of time was just neglected).
863#
864# The Palestinian Authority was established in 1993, and got hold of most
865# towns in the West Bank and Gaza by 1995. I know that in order to
866# demonstrate...independence, they have been switching to
867# summer time and back on a different schedule than Israel's, but I don't
868# know when this was started, or what algorithm is used (most likely the
869# Jordanian one).
870#
871# To summarize, the table should probably look something like that:
872#
873# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
874# ------------+-----------+-----------+-----------+-----------
875# Israel | Zion | Zion | Zion | Zion
876# West bank | Zion | Jordan | Zion | Jordan
877# Gaza | Zion | Egypt | Zion | Jordan
878#
879# I guess more info may be available from the PA's web page (if/when they
880# have one).
881
882# From Paul Eggert (1998-02-25):
883# Shanks writes that Gaza did not observe DST until 1957, but we'll go
884# with Shapir and assume that it observed DST from 1940 through 1947,
885# and that it used Jordanian rules starting in 1996.
886# We don't yet need a separate entry for the West Bank, since
887# the only differences between it and Gaza that we know about
888# occurred before our cutoff date of 1970.
889# However, as we get more information, we may need to add entries
890# for parts of the West Bank as they transitioned from Israel's rules
891# to Palestine's rules. If you have more info about this, please
892# send it to tz@elsie.nci.nih.gov for incorporation into future editions.
893
894# From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time,
895# forwarded by Ephraim Silverberg:
896#
897# Despite the fact that Israel changed over to daylight savings time
898# last week, the PLO Authority (PA) has decided not to turn its clocks
899# one-hour forward at this time. As a sign of independence from Israeli rule,
900# the PA has decided to implement DST in April.
