Change affecting past and future time zone abbreviations
The abbreviations for Hawaii-Aleutian standard and daylight times

as America/Honolulu was already using the new style.

Release 2015c - 2015-04-11 08:55:55 -0700
Changes affecting future time stamps
Egypt's spring-forward transition is at 24:00 on April's last Thursday,
not 00:00 on April's last Friday. 2015's transition will therefore be on

Changes affecting past time stamps
The 1982 zone shift in Pacific/Easter has been corrected, fixing a 2015a
regression. (Thanks to Stuart Bishop for reporting the problem.)
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: America/Antigua, America/Cayman,
Pacific/Midway, and Pacific/Saipan.
Changes affecting time zone abbreviations
Correct the 1992-2010 DST abbreviation in Volgograd from "MSK" to "MSD".

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.
