Summary of changes in tzdata2014g (2014-08-28 12:31:23 -0700):
  * Turks & Caicos is switching from US eastern time to UTC-4 year-round,
    modeled as a switch from EST/EDT to AST on 2014-11-02 at 02:00.
  * Time in Russia or the USSR before 1926 or so has been corrected by
    a few seconds for several zones, and a few minutes for
    Asia/Yekaterinburg.
  * The Portuguese decree of 1911-05-26 took effect on 1912-01-01, not
    on the date of the decree.  This affects 1911 time stamps in
    Africa/Bissau, Africa/Luanda, Atlantic/Azores, and Atlantic/Madeira.
  * Lisbon's pre-1912 GMT offset was -0:36:45 (rounded from -0:36:44.68),
    not -0:36:32.
  * Asia/Dhaka ended DST on 2009-12-31 at 24:00, not 23:59.
  * A new file 'backzone' contains data which may appeal to
    connoisseurs of old time stamps, although it is out of scope for
    the tz database, is often poorly sourced, and contains some data
    that is known to be incorrect.
  * Some more zones have been turned into links, when they differed
    from existing zones only for older time stamps.  As usual,
    these changes affect UTC offsets in pre-1970 time stamps only.
    Their old contents have been moved to the 'backzone' file.
  * Changes affecting documentation and commentary.
