7# From Paul Eggert <eggert@twinsun.com> (August 18, 1994):
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# Another source occasionally used is Edward W. Whitman, World Time Differences,
15# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
16# I found in the UCLA library.
17#
18# A reliable and entertaining source about time zones is
19# Derek Howse, Greenwich time and the discovery of the longitude,
20# Oxford University Press (1980).
21#
22# I invented the abbreviations marked `*' in the following table;
23# the rest are from earlier versions of this file, or from other sources.

165# From Guy Harris:
166# People's Republic of China. Yes, they really have only one time zone.
167
168# From Bob Devine (January 28, 1988):
169# No they don't. See TIME mag, February 17, 1986 p.52. Even though
170# China is across 4 physical time zones, before Feb 1, 1986 only the
171# Peking (Bejing) time zone was recognized. Since that date, China
172# has two of 'em -- Peking's and Urumqi (named after the capital of
173# the Xinjiang Uighur Autonomous Region). I don't know about DST for it.
174#
175# . . .I just deleted the DST table and this editor makes it too
176# painful to suck in another copy.. So, here is what I have for
177# DST start/end dates for Peking's time zone (info from AP):
178#
179# 1986 May 4 - Sept 14
180# 1987 mid-April - ??
181
182# From Paul Eggert <eggert@twinsun.com> (November 18, 1993):
183# According to Shanks, China started using DST in 1986,
184# but it's still all one big happy time zone.
185
186# From U. S. Naval Observatory (January 19, 1989):
187# CHINA 8 H AHEAD OF UTC ALL OF CHINA, INCL TAIWAN
188# CHINA 9 H AHEAD OF UTC APR 17 - SEP 10
189
190# From Paul Eggert <eggert@twinsun.com> (November 18, 1993):
191# Shanks writes that China switched from the Chinese calendar on 1912 Feb 12.
192# He also writes that China has had a single time zone since 1980 May 1,
193# and that they instituted DST on 1986 May 4; this contradicts Devine's
194# note about Time magazine, though apparently _something_ happened in 1986.

473# According to the Office of the Secretary General of the Ministry of
474# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
475# Each year they decide anew what havoc to wreak on the country. However,
476# there is a "supposed" set of rules which is subject to change depending
477# on the party the Minister of Interior, the size of the coalition
478# government, the phase of the moon and the direction of the wind. Hence,
479# changes may need to be made on a semi-annual basis. One thing is entrenched
480# in law, however: that there must be at least 150 days on daylight savings

527# Today's _Asahi Evening News_ (page 4) reports that Japan had
528# daylight saving between 1948 and 1951, but ``the system was discontinued
529# because the public believed it would lead to longer working hours.''
530# Shanks writes that daylight saving in Japan during those years was as follows:

165# From Guy Harris:

167
168# From Bob Devine (January 28, 1988):
169# No they don't. See TIME mag, February 17, 1986 p.52. Even though
170# China is across 4 physical time zones, before Feb 1, 1986 only the
171# Peking (Bejing) time zone was recognized. Since that date, China
172# has two of 'em -- Peking's and Urumqi (named after the capital of
173# the Xinjiang Uighur Autonomous Region). I don't know about DST for it.
174#
175# . . .I just deleted the DST table and this editor makes it too
176# painful to suck in another copy.. So, here is what I have for
177# DST start/end dates for Peking's time zone (info from AP):
178#
179# 1986 May 4 - Sept 14
180# 1987 mid-April - ??
181
182# From Paul Eggert <eggert@twinsun.com> (November 18, 1993):
183# According to Shanks, China started using DST in 1986,
184# but it's still all one big happy time zone.
185
186# From U. S. Naval Observatory (January 19, 1989):
187# CHINA 8 H AHEAD OF UTC ALL OF CHINA, INCL TAIWAN
188# CHINA 9 H AHEAD OF UTC APR 17 - SEP 10
189
190# From Paul Eggert <eggert@twinsun.com> (November 18, 1993):
191# Shanks writes that China switched from the Chinese calendar on 1912 Feb 12.
192# He also writes that China has had a single time zone since 1980 May 1,
193# and that they instituted DST on 1986 May 4; this contradicts Devine's
194# note about Time magazine, though apparently _something_ happened in 1986.

475# Each year they decide anew what havoc to wreak on the country. However,
476# there is a "supposed" set of rules which is subject to change depending
477# on the party the Minister of Interior, the size of the coalition
478# government, the phase of the moon and the direction of the wind. Hence,
479# changes may need to be made on a semi-annual basis. One thing is entrenched
480# in law, however: that there must be at least 150 days on daylight savings
481# time annually.
