Package: tzdata Severity: important Version: 2009o-1 Tags: patch User: ubuntu-devel@lists.ubuntu.com Usertags: origin-ubuntu ubuntu-patch karmic Hello, In https://launchpad.net/bugs/456322 it was reported that 2009o breaks DST in Bangladesh: $ zdump -v -c 2007,2015 Asia/Dhaka Asia/Dhaka Fri Jun 19 16:59:59 2009 UTC = Fri Jun 19 22:59:59 2009 BDT isdst=0 gmtoff=21600 Asia/Dhaka Fri Jun 19 17:00:00 2009 UTC = Fri Jun 19 23:00:00 2009 BDST isdst=0 gmtoff=21600 So DST is not considered at all, and clocks are off by an hour: $ LANG= date -u; LANG= TZ=Asia/Dhaka date Fri Oct 23 12:30:57 UTC 2009 Fri Oct 23 18:30:57 BDST 2009 This is due to our glibc not understanding open end dates on DST rules. This already happened when Bangladesh DST was introduced the first time (https://launchpad.net/bugs/383444) and back then it was discussed with upstream, who proposed to patch it to set an arbitrary end date. I did that for Ubuntu now by setting an arbitrary end date to Jan 1 2100 so that it works now: $ zdump -v -c 2007,2101 Asia/Dhaka Asia/Dhaka Fri Jun 19 16:59:59 2009 UTC = Fri Jun 19 22:59:59 2009 BDT isdst=0 gmtoff=21600 Asia/Dhaka Fri Jun 19 17:00:00 2009 UTC = Sat Jun 20 00:00:00 2009 BDST isdst=1 gmtoff=25200 Asia/Dhaka Thu Dec 31 16:59:59 2099 UTC = Thu Dec 31 23:59:59 2099 BDST isdst=1 gmtoff=25200 Asia/Dhaka Thu Dec 31 17:00:00 2099 UTC = Thu Dec 31 23:00:00 2099 BDT isdst=0 gmtoff=21600 $ LANG= date -u; LANG= TZ=Asia/Dhaka date Fri Oct 23 12:32:53 UTC 2009 Fri Oct 23 19:32:53 BDST 2009 Thanks for considering, Martin -- Martin Pitt | http://www.piware.de Ubuntu Developer (www.ubuntu.com) | Debian Developer (www.debian.org)diff -u tzdata-2009o/debian/changelog tzdata-2009o/debian/changelog --- tzdata-2009o/debian/changelog +++ tzdata-2009o/debian/changelog @@ -1,3 +1,11 @@ +tzdata (2009o-1ubuntu1) karmic; urgency=low + + * Add bdst-workaround.diff: Work around glibc not being able to cope with + open end dates by specifying an arbitrary one far in the future.
