[tz-announce] 2016e release of tz code and data available

Tue Jun 14 16:13:15 UTC 2016

The 2016e release of the tz code and data is available.  It reflects the 
following changes, which were either circulated on the tz mailing list or are 
relatively minor technical or administrative changes:

   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.)
