Release 2014j - 2014-11-10 17:37:11 -0800
Changes affecting current and future time stamps
Turks & Caicos' switch from US eastern time to UTC-4 year-round
did not occur on 2014-11-02 at 02:00. It's currently scheduled
for 2015-11-01 at 02:00. (Thanks to Chris Walton.)
Changes affecting past time stamps
Many pre-1989 time stamps have been corrected for Asia/Seoul and
Asia/Pyongyang, based on sources for the Korean-language Wikipedia
entry for time in Korea. (Thanks to Sanghyuk Jung.) Also, no
longer guess that Pyongyang mimicked Seoul time after World War II,
as this is politically implausible.
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.
The affected zones are: Africa/Addis_Ababa, Africa/Asmara,
Africa/Dar_es_Salaam, Africa/Djibouti, Africa/Kampala,
Africa/Mogadishu, Indian/Antananarivo, Indian/Comoro, and
Indian/Mayotte.
Changes affecting commentary
The commentary is less enthusiastic about Shanks as a source,
and is more careful to distinguish UT from UTC.
