News for the tz database
Release 2014h - 2014-09-25 18:59:03 -0700
Changes affecting past time stamps
America/Jamaica's 1974 spring-forward transition was Jan. 6, not Apr. 28.
Shanks says Asia/Novokuznetsk switched from LMT (not "NMT") on 1924-05-01,
not 1920-01-06. The old entry was based on a misinterpretation of Shanks.
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: Africa/Blantyre, Africa/Bujumbura,
Africa/Gaborone, Africa/Harare, Africa/Kigali, Africa/Lubumbashi,
Africa/Lusaka, Africa/Maseru, and Africa/Mbabane.
Changes affecting code
zdump -V and -v now output gmtoff= values on all platforms,
not merely on platforms defining TM_GMTOFF.
The tz library's localtime and mktime functions now set tzname to a value
appropriate for the requested time stamp, and zdump now uses this
on platforms not defining TM_ZONE, fixing a 2014g regression.
(Thanks to Tim Parenti for reporting the problem.)
The tz library no longer sets tzname if localtime or mktime fails.
zdump -c no longer mishandles transitions near year boundaries.
(Thanks to Tim Parenti for reporting the problem.)
An access to uninitalized data has been fixed.
(Thanks to Jörg Richter for reporting the problem.)
When THREAD_SAFE is defined, the code ports to the C11 memory model.
A memory leak has been fixed if ALL_STATE and THREAD_SAFE are defined
and two threads race to initialize data used by gmtime-like functions.
(Thanks to Andy Heninger for reporting the problems.)
Changes affecting build procedure
'make check' now checks better for properly-sorted data.
Changes affecting documentation and commentary
zdump's gmtoff=N output is now documented, and its isdst=D output
is now documented to possibly output D values other than 0 or 1.
zdump -c's treatment of years is now documented to use the
Gregorian calendar and Universal Time without leap seconds,
and its behavior at cutoff boundaries is now documented better.
(Thanks to Arthur David Olson and Tim Parenti for reporting the problems.)
Programs are now documented to use the proleptic Gregorian calendar.
(Thanks to Alan Barrett for the suggestion.)
Fractional-second GMT offsets have been documented for civil time
in 19th-century Chennai, Jakarta, and New York.
