I noticed that the timezone description for chinese
timezones use DST.
Aparently the chinese
governament stopped using DST in 1992.
To fix the problem I changed my copy asia file and regenerated ICU4J resources (my copy).
# China
# From Guy Harris:
# People's Republic of China. Yes, they really have only one time
zone.
# From Bob Devine (1988-01-28):
# No they don't. See TIME mag, 1986-02-17 p.52.
Even though
# China is across 4 physical time
zones, before Feb 1, 1986 only the
# Peking
(Bejing) time zone was recognized. Since that date, China
# has two of 'em -- Peking's and Urumqi (named after the
capital of
# the Xinjiang Uyghur Autonomous
Region). I don't know about DST for it.
#
# . . .I just deleted the DST table
and this editor makes it too
# painful to
suck in another copy.. So, here is what I have for
# DST start/end dates for Peking's time zone (info from
AP):
#
# 1986 May 4 - Sept 14
# 1987 mid-April - ??
# From U. S. Naval Observatory (1989-01-19):
#
CHINA
8 H AHEAD OF UTC ALL OF CHINA, INCL TAIWAN
#
CHINA
9 H AHEAD OF UTC APR 17 - SEP 10
# From Paul Eggert <eggert@twinsun.com>
(1995-12-19):
# Shanks writes that China has
had a single time zone since 1980 May 1,
#
observing summer DST from 1986 through 1991; this contradicts Devine's
# note about Time magazine, though apparently
_something_ happened in 1986.
# Go with
Shanks for now. I made up names for the other pre-1980 time zones.
