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

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.)

Subject: [tz] [tz-announce] 2016f release of tz code and data available

The 2016f 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

     The Egyptian government changed its mind on short notice, and
     Africa/Cairo will not introduce DST starting 2016-07-07 after all.
     (Thanks to Mina Samuel.)

     Asia/Novosibirsk switches from +06 to +07 on 2016-07-24 at 02:00.
     (Thanks to Stepan Golosunov.)

   Changes to past and future time stamps

     Asia/Novokuznetsk and Asia/Novosibirsk now use numeric time zone
     abbreviations instead of invented ones.

   Changes affecting past time stamps

     Europe/Minsk's 1992-03-29 spring-forward transition was at 02:00 not 00:00.
     (Thanks to Stepan Golosunov.)
