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 (3rd edition),
11# San Diego: ACS Publications, Inc. (1991).
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;

86# <edd@AIC.NET> reported today that Yerevan probably won't use DST this year,

161# From Guy Harris:
162# People's Republic of China. Yes, they really have only one time zone.
163
164# From Bob Devine (1988-01-28):
165# No they don't. See TIME mag, 1986-02-17 p.52. Even though
166# China is across 4 physical time zones, before Feb 1, 1986 only the
167# Peking (Bejing) time zone was recognized. Since that date, China
168# has two of 'em -- Peking's and Urumqi (named after the capital of
169# the Xinjiang Uighur Autonomous Region). I don't know about DST for it.
170#
171# . . .I just deleted the DST table and this editor makes it too
172# painful to suck in another copy.. So, here is what I have for
173# DST start/end dates for Peking's time zone (info from AP):
174#
175# 1986 May 4 - Sept 14
176# 1987 mid-April - ??
177
178# From U. S. Naval Observatory (1989-01-19):
179# CHINA 8 H AHEAD OF UTC ALL OF CHINA, INCL TAIWAN
180# CHINA 9 H AHEAD OF UTC APR 17 - SEP 10
181
182# From Paul Eggert <eggert@twinsun.com> (1995-12-19):
183# Shanks writes that China has had a single time zone since 1980 May 1,
184# observing summer DST from 1986 through 1991; this contradicts Devine's
185# note about Time magazine, though apparently _something_ happened in 1986.
186# Go with Shanks for now. I made up names for the other pre-1980 time zones.

509
510# According to the Office of the Secretary General of the Ministry of
511# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
512# Each year they decide anew what havoc to wreak on the country. However,
513# there is a "supposed" set of rules which is subject to change depending
514# on the party the Minister of Interior, the size of the coalition
515# government, the phase of the moon and the direction of the wind. Hence,
516# changes may need to be made on a semi-annual basis. One thing is entrenched
517# in law, however: that there must be at least 150 days of daylight savings
518# time annually. Ever since 1993, the change to daylight savings time is
519# on a Thursday night from midnight IST to 1 a.m IDT. The change back to
520# standard time is on a Saturday night from midnight daylight savings time
521# to 11 p.m. standard time. 1996 is an exception to this rule where the
522# change back to standard time took place on Sunday night instead of Saturday
523# night to avoid conflicts with the Jewish New Year.

161# From Guy Harris:
162# People's Republic of China. Yes, they really have only one time zone.
163
164# From Bob Devine (1988-01-28):
165# No they don't. See TIME mag, 1986-02-17 p.52. Even though
166# China is across 4 physical time zones, before Feb 1, 1986 only the
167# Peking (Bejing) time zone was recognized. Since that date, China
168# has two of 'em -- Peking's and Urumqi (named after the capital of
169# the Xinjiang Uighur Autonomous Region). I don't know about DST for it.
170#
171# . . .I just deleted the DST table and this editor makes it too
172# painful to suck in another copy.. So, here is what I have for
173# DST start/end dates for Peking's time zone (info from AP):
174#
175# 1986 May 4 - Sept 14
176# 1987 mid-April - ??
177
178# From U. S. Naval Observatory (1989-01-19):
179# CHINA 8 H AHEAD OF UTC ALL OF CHINA, INCL TAIWAN
180# CHINA 9 H AHEAD OF UTC APR 17 - SEP 10
181
182# From Paul Eggert <eggert@twinsun.com> (1995-12-19):
183# Shanks writes that China has had a single time zone since 1980 May 1,
184# observing summer DST from 1986 through 1991; this contradicts Devine's
185# note about Time magazine, though apparently _something_ happened in 1986.
186# Go with Shanks for now. I made up names for the other pre-1980 time zones.

508# From Ephraim Silverberg (ephraim@cs.huji.ac.il), 1997-03-04:
509
510# According to the Office of the Secretary General of the Ministry of
511# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
512# Each year they decide anew what havoc to wreak on the country. However,
513# there is a "supposed" set of rules which is subject to change depending
514# on the party the Minister of Interior, the size of the coalition
515# government, the phase of the moon and the direction of the wind. Hence,
516# changes may need to be made on a semi-annual basis. One thing is entrenched
517# in law, however: that there must be at least 150 days of daylight savings
518# time annually. Ever since 1993, the change to daylight savings time is
519# on a Thursday night from midnight IST to 1 a.m IDT. The change back to
520# standard time is on a Saturday night from midnight daylight savings time
521# to 11 p.m. standard time. 1996 is an exception to this rule where the
522# change back to standard time took place on Sunday night instead of Saturday
523# night to avoid conflicts with the Jewish New Year.
