[tz] Azerbaijan canceled daylight saving time

Thanks to everybody who sent in a heads-up about Azerbaijan. Release 2016c of the tz database (released today) has an update for Asia/Baku that should bring it up to date. Please see: http://mm.icann.org/pipermail/tz-announce/2016-March/000037.html Although 2016c should eventually propagate into the systems that use the tz database, this propagation process may take a while. As a temporary workaround Azerbaijani users can set the time zone to some other value in order to have computer-based clocks work correctly for time stamps after this weekend. Possible TZ settings include 'AZT-4', 'Asia/Dubai', 'Asia/Tbilisi', 'Asia/Yerevan', and 'Europe/Samara'.
