Release Notes
Changes affecting future timestamps
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
Thursday, April 30 at 24:00, not Friday, April 24 at 00:00. Similar fixes
apply to 2026, 2037, 2043, etc. (Thanks to Steffen Thorsen.)
Changes affecting past timestamps
The following changes affect some pre-1991 Chile-related timestamps
in America/Santiago, Antarctica/Palmer, and Pacific/Easter.
The 1910 transition was January 10, not January 1.
The 1918 transition was September 10, not September 1.
The UT -04 time observed from 1932 to 1942 is now considered to
be standard time, not year-round DST.
Santiago observed DST (UT -03) from 1946-07-15 through
1946-08-31, then reverted to standard time, then switched to -05
on 1947-04-01.
Assume transitions before 1968 were at 00:00, since we have no data
saying otherwise.
The spring 1988 transition was 1988-10-09, not 1988-10-02.
The fall 1990 transition was 1990-03-11, not 1990-03-18.
Assume no UT offset change for Pacific/Easter on 1890-01-01,
and omit all transitions on Pacific/Easter from 1942 through 1946
since we have no data suggesting that they existed.
One more zone has been turned into a link, as it differed
from an existing zone only for older timestamps. As usual,
this change affects UT offsets in pre-1970 timestamps only.
The zone's old contents have been moved to the 'backzone' file.
The affected zone is America/Montreal.
