Updated to tzdata2016e.

1:   News for the tz database    + Release 2016e - 2016-06-14 08:46:16 -0700 +  +  Changes affecting future time stamps +  +  Africa/Cairo observes DST in 2016 from July 7 to the end of October. +  Guess October 27 and 24:00 transitions. (Thanks to Steffen Thorsen.) +  For future years, guess April's last Thursday to October's last +  Thursday except for Ramadan. +  +  Changes affecting past time stamps +  +  Locations while uninhabited now use '-00', not 'zzz', as a +  placeholder time zone abbreviation. This is inspired by Internet +  RFC 3339 and is more consistent with numeric time zone +  abbreviations already used elsewhere. The change affects several +  arctic and antarctic locations, e.g., America/Cambridge_Bay before +  1920 and Antarctica/Troll before 2005. +  +  Asia/Baku's 1992-09-27 transition from +04 (DST) to +04 (non-DST) was +  at 03:00, not 23:00 the previous day. (Thanks to Michael Deckers.) +  +  Changes to code +  +  zic now outputs a dummy transition at time 2**31 - 1 in zones +  whose POSIX-style TZ strings contain a '<'. This mostly works +  around Qt bug 53071 <https://bugreports.qt.io/browse/QTBUG-53071>. +  (Thanks to Zhanibek Adilbekov for reporting the Qt bug.) +  +  Changes affecting documentation and commentary +  +  tz-link.htm says why governments should give plenty of notice for +  time zone or DST changes, and refers to Matt Johnson's blog post. +  +  tz-link.htm mentions Tzdata for Elixir. (Thanks to Matt Johnson.) +  +  + Release 2016d - 2016-04-17 22:50:29 -0700 +  +  Changes affecting future time stamps +  +  America/Caracas switches from -0430 to -04 on 2016-05-01 at 02:30. +  (Thanks to Alexander Krivenyshev for the heads-up.) +  +  Asia/Magadan switches from +10 to +11 on 2016-04-24 at 02:00. +  (Thanks to Alexander Krivenyshev and Matt Johnson.) +  +  New zone Asia/Tomsk, split off from Asia/Novosibirsk. It covers +  Tomsk Oblast, Russia, which switches from +06 to +07 on 2016-05-29 +  at 02:00. (Thanks to Stepan Golosunov.) +  +  Changes affecting past time stamps +  +  New zone Europe/Kirov, split off from Europe/Volgograd. It covers +  Kirov Oblast, Russia, which switched from +04/+05 to +03/+04 on +  1989-03-26 at 02:00, roughly a year after Europe/Volgograd made +  the same change. (Thanks to Stepan Golosunov.) +  +  Russia and nearby locations had daylight-saving transitions on +  1992-03-29 at 02:00 and 1992-09-27 at 03:00, instead of on +  1992-03-28 at 23:00 and 1992-09-26 at 23:00. (Thanks to Stepan +  Golosunov.) +  +  Many corrections to historical time in Kazakhstan from 1991 +  through 2005. (Thanks to Stepan Golosunov.) Replace Kazakhstan's +  invented time zone abbreviations with numeric abbreviations. +  +  Changes to commentary +  +  Mention Internet RFCs 7808 (TZDIST) and 7809 (CalDAV time zone references). +  +    Release 2016c - 2016-03-23 00:51:27 -0700       Changes affecting future time stamps
28:      Release 2016b - 2016-03-12 17:30:14 -0800    +  Compatibility note +  +  Starting with release 2016b, some data entries cause zic implementations +  derived from tz releases 2005j through 2015e to issue warnings like +  "time zone abbreviation differs from POSIX standard (+03)". +  These warnings should not otherwise affect zic's output and can safely be +  ignored on today's platforms, as the warnings refer to a restriction in +  POSIX.1-1988 that was removed in POSIX.1-2001. One way to suppress the +  warnings is to upgrade to zic derived from tz releases 2015f and later. +     Changes affecting future time stamps       New zones Europe/Astrakhan and Europe/Ulyanovsk for Astrakhan and
