i:
The compile-time flag NOSOLAR has been removed, as nowadays the
benefit of slightly shrinking runtime table size is outweighed by the
cost of disallowing potential future updates that exceed old limits.
h:
Fix localtime overflow bugs with 32-bit unsigned time_t.
zdump no longer assumes sscanf returns maximal values on overflow.
g:
'zic' now runs on platforms that lack both hard links and symlinks.
(Thanks to Theo Veenker for reporting the problem, for MinGW.)
Also, fix some bugs on platforms that lack hard links but have symlinks.
'zic -v' again warns that Asia/Tehran has no POSIX environment variable
to predict the far future, fixing a bug introduced in 2013e.
f:
The types of the global variables 'timezone' and 'altzone' (if present)
have been changed back to 'long'. This is required for 'timezone'
by POSIX, and for 'altzone' by common practice, e.g., Solaris 11.
These variables were originally 'long' in the tz code, but were
mistakenly changed to 'time_t' in 1987; nobody reported the
incompatibility until now. The difference matters on x32, where
'long' is 32 bits and 'time_t' is 64. (Thanks to Elliott Hughes.)
Major changes from tzdata2013d to tzdata2013e:
Fiji (Pacific/Fiji) DST in 2013 starts on October 27, not October 20.
Several zones have been turned into links, either to correct errors,
or where the differences were in older data (before 1943) that was
thought to be unreliable.
Some time zone abbreviations have been changed.
Major changes from tzdata2013e to tzdata2013f:
Tocantins, Brazil (America/Araguaina) DST will not start in September
2013.
Jordan (Asia/Amman) moves to permanent UTC+3 (instead of UTC+2 with
permanent DST since 2012).
Palestine (Asia/Hebron and Asia/Gaza) will end DST at 00:00, not
01:00, as from September 2013.
Major changes from tzdata2013f to tzdata2013g:
Morocco (Africa/Casablanca) now observes DST from the last Sunday
in March to the last Sunday in October, not April to September.
respectively.
Major changes from tzdata2013g to tzdata2013h:
Libya (Africa/Tripoli) has switched its time zone back to UTC+2
without DST, instead of UTC+1 with DST.
Western Sahara (Africa/El_Aaiun) uses Morocco's DST rules.
Acre, Brazil (America/Rio_Branco) and (we guess) western Amazonas,
Brazil (America/Eirunepe), will switch from UTC-4 to UTC-5 on
2013-11-10.
Add entries for DST transitions in Morocco in the year 2038. This
avoids some year-2038 glitches introduced in 2013g.
Major changes from tzdata2013h to tzdata2013i:
Jordan (Asia/Amman) switches back to UTC+2 standard time at 00:00 on
December 20, 2013. The 2006-2011 DST transition schedule is planned
to resume in 2014. The switch to permanent UTC+3 is cancelled.
In 2004, Cuba (America/Havana) began DST on March 28, not April 4.
The files solar87, solar88, and solar89 are no longer distributed.
The zones built from those files (Asia/Riyadh{87,88,89}) and
Mideast/Riyadh{87,88,89}) are no longer installed. They were a
negative experiment -- that is, a demonstration that tz data can
represent solar time only with some difficulty and error. Their
presence in the distribution caused confusion, as Riyadh civil time
was generally not solar time in those years.
