proposed time zone package changes for Samoa (comments), Bangladesh, and Pakistan
At the end of this message are proposed changes to time zone files, summarized here: asia Bangladesh does not go off DST in 2009 Pakistan Goes off DST November 1 2009 (and in future years) australasia Samoa information on Samoa NOT starting DST in 2009 (comments only) I've only included changes involving 2009; other data changes (as well as tz-art additions) are in the pipeline. The adoption of "permanent" DST in Bangladesh means there's another place that can't be represented by a POSIX time zone environment variable; this may cause some grief. We may want to change the trailing... 6:00 1:00 BDST ...line for Bangladesh to... 5:00 - BDST ...either in the short term or the long term. If no one finds problems, expect these changes to show up on the ftp site on 2009-10-19. --ado ------- asia ------- *** /tmp/geta23160 Wed Oct 14 16:50:00 2009 --- /tmp/getb23160 Wed Oct 14 16:50:00 2009 *************** *** 1,5 **** # <pre> ! # @(#)asia 8.41 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,5 ---- # <pre> ! # @(#)asia 8.42 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 172,183 **** # # No DST end date has been announced yet. ! # From Arthur David Olson (2009-07-11): ! # Arbitrarily end DST at the end of 2009 so that a POSIX-sytle time zone string ! # can appear in the Dhaka binary file and for the benefit of old glibc ! # reimplementations of the time zone software that mishandle permanent DST. ! # A change will be required once the end date is known. # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Asia/Dhaka 6:01:40 - LMT 1890 5:53:20 - HMT 1941 Oct # Howrah Mean Time? --- 172,202 ---- # # No DST end date has been announced yet. ! # From Alexander Krivenyshev (2009-09-25): ! # Bangladesh won't go back to Standard Time from October 1, 2009, ! # instead it will continue DST measure till the cabinet makes a fresh decision. ! # ! # Following report by same newspaper-"The Daily Star Friday": ! # "DST change awaits cabinet decision-Clock won't go back by 1-hr from Oct 1" ! # <a href="http://www.thedailystar.net/newDesign/news-details.php?nid=107021"> ! # http://www.thedailystar.net/newDesign/news-details.php?nid=107021 ! # </a> ! # or ! # <a href="http://www.worldtimezone.com/dst_news/dst_news_bangladesh04.html"> ! # http://www.worldtimezone.com/dst_news/dst_news_bangladesh04.html ! # </a> + # From Steffen Thorsen (2009-10-13): + # IANS (Indo-Asian News Service) now reports: + # Bangladesh has decided that the clock advanced by an hour to make + # maximum use of daylight hours as an energy saving measure would + # "continue for an indefinite period." + # + # One of many places where it is published: + # <a href="http://www.thaindian.com/newsportal/business/bangladesh-to-continue-indefinitely-with-advanced-time_100259987.html"> + # http://www.thaindian.com/newsportal/business/bangladesh-to-continue-indefini... + # </a> + # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Asia/Dhaka 6:01:40 - LMT 1890 5:53:20 - HMT 1941 Oct # Howrah Mean Time? *************** *** 186,193 **** 6:30 - BURT 1951 Sep 30 6:00 - DACT 1971 Mar 26 # Dacca Time 6:00 - BDT 2009 Jun 19 23:00 # Bangladesh Time ! 6:00 1:00 BDST 2010 ! 6:00 - BDT # Bhutan # Zone NAME GMTOFF RULES FORMAT [UNTIL] --- 205,211 ---- 6:30 - BURT 1951 Sep 30 6:00 - DACT 1971 Mar 26 # Dacca Time 6:00 - BDT 2009 Jun 19 23:00 # Bangladesh Time ! 6:00 1:00 BDST # Bhutan # Zone NAME GMTOFF RULES FORMAT [UNTIL] *************** *** 1684,1696 **** # http://www.thenews.com.pk/updates.asp?id=87168 # </a> # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Pakistan 2002 only - Apr Sun>=2 0:01 1:00 S Rule Pakistan 2002 only - Oct Sun>=2 0:01 0 - Rule Pakistan 2008 only - Jun 1 0:00 1:00 S Rule Pakistan 2008 only - Nov 1 0:00 0 - !

Surely that last line should read "BDT", not "BDST". That has been the usual style in the past, when countries have made permanent switches of an hour (initially, as "daylight savimg" perhaps), but eventually permanent. For now, though, I expect it's OK to keep calling it "BDST", as it may well switch back.
