Release Notes
Change affecting binary data format:
The zone offset at the end of version-2-format zone files is now
allowed to be 24:00, as per POSIX.1-2008. (Thanks to Arthur David Olson.)
Changes affecting current and future timestamps:
Chile's 2013 rules, and we guess rules for 2014 and later, will be
the same as 2012, namely Apr Sun>=23 03:00 UTC to Sep Sun>=2 04:00 UTC.
(Thanks to Steffen Thorsen and Robert Elz.)
New Zones Asia/Khandyga, Asia/Ust-Nera, Europe/Busingen.
(Thanks to Tobias Conradi and Arthur David Olson.)
Many changes affect historical timestamps before 1940.
These were deduced from: Milne J. Civil time. Geogr J. 1899
Feb;13(2):173-94 <https://www.jstor.org/stable/1774359>.
Changes affecting the code:
Fix zic bug that mishandled Egypt's 2010 changes (this also affected
the data). (Thanks to Arthur David Olson.)
Fix localtime bug when time_t is unsigned and data files were generated
by a signed time_t system. (Thanks to Doug Bailey for reporting and
to Arthur David Olson for fixing.)
Allow the email address for bug reports to be set by the packager.
The default is tz@iana.org, as before. (Thanks to Joseph S. Myers.)
Update HTML checking to be compatible with Ubuntu 12.10.
Check that files are a safe subset of ASCII. At some point we may
relax this requirement to a safe subset of UTF-8. Without the
check, some non-UTF-8 encodings were leaking into the distribution.
Commentary changes:
Restore a comment about copyright notices that was inadvertently deleted.
(Thanks to Arthur David Olson.)
Improve the commentary about which districts observe what times
in Russia. (Thanks to Oscar van Vlijmen and Arthur David Olson.)
Add web page links to tz.js.
Add "Run by the Monkeys" to tz-art. (Thanks to Arthur David Olson.)
