shortening too-long abbreviations.

News for the tz database
+Release 2015a - 2015-01-29 22:35:20 -0800
+
+ Changes affecting future time stamps
+
+ The Mexican state of Quintana Roo, represented by America/Cancun,
+ will shift from Central Time with DST to Eastern Time without DST
+ on 2015-02-01 at 02:00. (Thanks to Steffen Thorsen and Gwillim Law.)
+
+ Chile will not change clocks in April or thereafter; its new standard time
+ will be its old daylight saving time. This affects America/Santiago,
+ Pacific/Easter, and Antarctica/Palmer. (Thanks to Juan Correa.)
+
+ New leap second 2015-06-30 23:59:60 UTC as per IERS Bulletin C 49.
+ (Thanks to Tim Parenti.)
+
+ Changes affecting past time stamps
+
+ Iceland observed DST in 1919 and 1921, and its 1939 fallback
+ transition was Oct. 29, not Nov. 29. Remove incorrect data from
+ Shanks about time in Iceland between 1837 and 1908.
+
+ 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: Asia/Aden, Asia/Bahrain, Asia/Kuwait,
+ and Asia/Muscat.
+
+ Changes affecting code
+
+ tzalloc now scrubs time zone abbreviations compatibly with the way
+ that tzset always has, by replacing invalid bytes with '_' and by
+ shortening too-long abbreviations.
+
+ tzselect ports to POSIX awk implementations, no longer mishandles
+ POSIX TZ settings when GNU awk is used, and reports POSIX TZ
+ settings to the user. (Thanks to Stefan Kuhn.)
+
+ Changes affecting build procedure
+
+ 'make check' now checks for links to links in the data.
+ One such link (for Africa/Asmera) has been fixed.
+ (Thanks to Stephen Colebourne for pointing out the problem.)
+
+ Changes affecting commentary
+
+ The leapseconds file commentary now mentions the expiration date.
+ (Problem reported by Martin Burnicki.)
+
+ Update Mexican Library of Congress URL.
