Go with Shanks & Pottenger, even 90158421Swollman# when they disagree with others. Edgar Der-Danieliantz 91153670Swollman# reported (1996-05-04) that Yerevan probably wouldn't use DST 9243014Swollman# in 1996, though it did use DST in 1995. IATA SSIM (1991/1998) reports that 9343014Swollman# Armenia switched from 3:00 to 4:00 in 1998 and observed DST after 1991, 9443014Swollman# but started switching at 3:00s in 1998. 952742Swollman# Zone NAME GMTOFF RULES FORMAT [UNTIL] 962742SwollmanZone Asia/Yerevan 2:58:00 - LMT 1924 May 2 9719878Swollman 3:00 - YERT 1957 Mar # Yerevan Time 9819878Swollman 4:00 RussiaAsia YER%sT 1991 Mar 31 2:00s 9919878Swollman 3:00 1:00 YERST 1991 Sep 23 # independence 10058787Sru 3:00 RussiaAsia AM%sT 1995 Sep 24 2:00s 10143014Swollman 4:00 - AMT 1997 10275267Swollman 4:00 RussiaAsia AM%sT 1032742Swollman 1042742Swollman# Azerbaijan 105153670Swollman# From Rustam Aliyev of the Azerbaijan Internet Forum (2005-10-23): 106153670Swollman# According to the resolution of Cabinet of Ministers, 1997 107153670Swollman# Resolution available at: http://aif.az/docs/daylight_res.pdf 10843014Swollman# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S 109153670SwollmanRule Azer 1997 max - Mar lastSun 4:00 1:00 S 110153670SwollmanRule Azer 1997 max - Oct lastSun 5:00 0 - 1112742Swollman# Zone NAME GMTOFF RULES FORMAT [UNTIL] 1122742SwollmanZone Asia/Baku 3:19:24 - LMT 1924 May 2 11319878Swollman 3:00 - BAKT 1957 Mar # Baku Time 11419878Swollman 4:00 RussiaAsia BAK%sT 1991 Mar 31 2:00s 11519878Swollman 3:00 1:00 BAKST 1991 Aug 30 # independence 116149514Swollman 3:00 RussiaAsia AZ%sT 1992 Sep lastSat 23:00 11720094Swollman 4:00 - AZT 1996 # Azerbaijan time 11843014Swollman 4:00 EUAsia AZ%sT 1997 11943014Swollman 4:00 Azer AZ%sT 1202742Swollman 1212742Swollman# Bahrain 1222742Swollman# Zone NAME GMTOFF RULES FORMAT [UNTIL] 12367578SwollmanZone Asia/Bahrain 3:22:20 - LMT 1920 # Al Manamah 1242742Swollman 4:00 - GST 1972 Jun 1252742Swollman 3:00 - AST 1262742Swollman 1272742Swollman# Bangladesh 1282742Swollman# Zone NAME GMTOFF RULES FORMAT [UNTIL] 12975267SwollmanZone Asia/Dhaka 6:01:40 - LMT 1890 13019878Swollman 5:53:20 - HMT 1941 Oct # Howrah Mean Time? 13119878Swollman 6:30 - BURT 1942 May 15 # Burma Time 1322742Swollman 5:30 - IST 1942 Sep 13319878Swollman 6:30 - BURT 1951 Sep 30 13419878Swollman 6:00 - DACT 1971 Mar 26 # Dacca Time 13519878Swollman 6:00 - BDT # Bangladesh Time 1362742Swollman 1372742Swollman# Bhutan 1382742Swollman# Zone NAME GMTOFF RULES FORMAT [UNTIL] 13967578SwollmanZone Asia/Thimphu 5:58:36 - LMT 1947 Aug 15 # or Thimbu 1402742Swollman 5:30 - IST 1987 Oct 14119878Swollman 6:00 - BTT # Bhutan Time 1422742Swollman 1432742Swollman# British Indian Ocean Territory 14486222Swollman# Whitman and the 1995 CIA time zone map say 5:00, but the 14586222Swollman# 1997 and later maps say 6:00.

Even though 1832742Swollman# China is across 4 physical time zones, before Feb 1, 1986 only the 1842742Swollman# Peking (Bejing) time zone was recognized. Since that date, China 1852742Swollman# has two of 'em -- Peking's and Urumqi (named after the capital of 18693799Swollman# the Xinjiang Uyghur Autonomous Region).

And yes, there are official 219163302Sru# Chinese names for these locales (before 1949). 220169811Swollman# 221163302Sru# From Jesper Norgaard Welen (2006-07-14): 222163302Sru# I have investigated the timezones around 1970 on the 223163302Sru# http://www.astro.com/atlas site [with provinces and county 224163302Sru# boundaries summarized below].... A few other exceptions were two 225163302Sru# counties on the Sichuan side of the Xizang-Sichuan border, 226163302Sru# counties Dege and Baiyu which lies on the Sichuan side and are 227163302Sru# therefore supposed to be GMT+7, Xizang region being GMT+6, but Dege 228163302Sru# county is GMT+8 according to astro.com while Baiyu county is GMT+6 229163302Sru# (could be true), for the moment I am assuming that those two 230163302Sru# counties are mistakes in the astro.com data. 231163302Sru 232181421Sedwin# From Paul Eggert (2008-02-11): 233181421Sedwin# I just now checked Google News for western news sources that talk 234181421Sedwin# about China's single time zone, and couldn't find anything before 1986 235181421Sedwin# talking about China being in one time zone. (That article was: Jim 236181421Sedwin# Mann, "A clumsy embrace for another western custom: China on daylight 237181421Sedwin# time--sort of", Los Angeles Times, 1986-05-05. By the way, this 238181421Sedwin# article confirms the tz database's data claiming that China began 239181421Sedwin# observing daylight saving time in 1986. 240181421Sedwin# 241181421Sedwin# From Thomas S. Mullaney (2008-02-11): 242181421Sedwin# I think you're combining two subjects that need to treated 243181421Sedwin# separately: daylight savings (which, you're correct, wasn't 244181421Sedwin# implemented until the 1980s) and the unified time zone centered near 245181421Sedwin# Beijing (which was implemented in 1949). Briefly, there was also a 246181421Sedwin# "Lhasa Time" in Tibet and "Urumqi Time" in Xinjiang.

This is what I was 152793799Swollman# told, but I believe that the actual time of change may be 00:00; the 152893799Swollman# 00:01 was to make it clear which day it was on. 152993799Swollman 153093799Swollman# From Paul Eggert (2002-03-15): 153193799Swollman# Jesper Norgaard found this URL: 153293799Swollman# http://www.pak.gov.pk/public/news/app/app06_dec.htm 153393799Swollman# (dated 2001-12-06) which says that the Cabinet adopted a scheme "to 153493799Swollman# advance the clocks by one hour on the night between the first 153593799Swollman# Saturday and Sunday of April and revert to the original position on 153693799Swollman# 15th October each year". This agrees with McDow's 04-07 at 00:00, 153793799Swollman# but disagrees about the October transition, and makes it sound like 153893799Swollman# it's not on a trial basis. Also, the "between the first Saturday 153993799Swollman# and Sunday of April" phrase, if taken literally, means that the 154093799Swollman# transition takes place at 00:00 on the first Sunday on or after 04-02. 154193799Swollman 1542114173Swollman# From Paul Eggert (2003-02-09): 1543114173Swollman# DAWN <http://www.dawn.com/2002/10/06/top13.htm> reported on 2002-10-05 1544114173Swollman# that 2002 DST ended that day at midnight.

It was never formally annexed to Egypt, 165143014Swollman# though. 165243014Swollman# 165343014Swollman# The rest of Palestine was under Jordanian rule at that time, formally 165443014Swollman# annexed in 1950 as the West Bank (and the word "Trans" was dropped from 165543014Swollman# the country's previous name of "the Hashemite Kingdom of the 165643014Swollman# Trans-Jordan"). So the rules for Jordan for that time apply. Major 165743014Swollman# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and 165843014Swollman# East Jerusalem. 165943014Swollman# 166043014Swollman# Both areas were occupied by Israel in June 1967, but not annexed (except 166143014Swollman# for East Jerusalem).
