Here are proposed tz changes prompted by the recent news that our current time stamps for Kazakhstan are incorrect. * Kazakhstan no longer observes DST. Thanks to Olzhas Kalamkaliyev for this info. * Add guesses for when the Chagos Archipelago and the Cocos Islands introduced standard time (around 1900, in both cases). Thanks to Oscar van Vlijmen for noting the problem. * Western Samoa changed its name to Samoa; this affects the data in iso3166.tab, but not in the tz database proper. Thanks to Oscar van Vlijmen for this. Commentary changes only: * Add coordinates for more Antarctic bases, and add commentary about local time for ships at sea. Thanks to Oscar van Vlijmen for this. * Add a URL pointing to seizethedaylight.com. =================================================================== RCS file: RCS/asia,v retrieving revision 2005.6 retrieving revision 2005.6.0.1 diff -pu -r2005.6 -r2005.6.0.1 --- asia 2005/03/01 13:44:10 2005.6 +++ asia 2005/03/29 09:06:54 2005.6.0.1 @@ -137,8 +137,12 @@ Zone Asia/Thimphu 5:58:36 - LMT 1947 Aug # British Indian Ocean Territory # Whitman and the 1995 CIA time zone map say 5:00, but the # 1997 and later maps say 6:00.
