Change affecting past and future time zone abbreviations

The abbreviations for Hawaii-Aleutian standard and daylight times

Egypt's spring-forward transition is at 24:00 on April's last Thursday,

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

Changes affecting past time stamps

Many pre-1989 time stamps have been corrected for Asia/Seoul and
