The files ftp://munnari.oz.au/pub/tzdata2012b.tar.gz ftp://munnari.oz.au/pub/tzcode2012b.tar.gz are now available. These reflect the changes circulated earlier today on the list. There is just one change to tzcode2012b (compared witth 2012a): the Makefile that was accidentally included with 2012a has been replaced with the version that should have been there, which is identical with the previous version (from tzcode2011i). For people upgrading directly from 2011i to 2012b, the changes in tzcode are just to the README and tz-art.htm and tz-link.htm and reflect changes to the mailing list address & subscription URLs, and the code distribution URLs and methods. tz-link.htm also has a link to DateTime::TimeZone::Tzfile added. There are just two changes in tzdata2012b compared with 2012a. Most significantly, summer time in Cuba has been delayed 3 weeks (now starts April 1 rather than March 11). Since Mar 11 (the old start date, as listed in 2012a) is just a little over a week away, this change is urgent. Less importantly, an excess tab in one of the changes in zone.tab in 2012a has been removed. Compared to the last long lived distribution (given tzdata2012a existed less than a day) which was tzdata2011n, the other major changes are: Chile 2011/2012 and 2012/2013 summer time date adjustments. Falkland Islands onto permanent summer time (we're assuming for the foreseeable future, though 2012 is all we're fairly certain of.) Armenia has abolished Summer Time. Tokelau jumped the International Date Line back last December (just the same as their near neighbour, Samoa). America/Creston is a new zone for a small area of British Columbia There will be a leapsecod 2012-06-30 23:59:60 UTC. Other minor changes are: Corrections to 1918 Canadian summer time end dates.
