Changes from tzdata2012j to tzdata2013a:
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 Arthor David Olson.)
Changes affecting current and future time stamps:
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 time stamps before 1940.
These were deduced from: Milne J. Civil time. Geogr J. 1899
Feb;13(2):173-94 <http://www.jstor.org/stable/1774359>.

I was first going to do this by doing automatic replacements of special
macros within the tests.7 file, but that turned out to be too complex
and confusing.
Instead, just rename the previous tests.7 to tests.atf.7 and add a new
tests.kyua.7 file. Choose which one to install as tests(7) depending on
the MKKYUA knob.
This is suboptimal: the current high-level definitions of test programs
in the Makefiles do not carry enough information to support all the
features of Kyuafiles. For example, it is not possible to register test
programs that do *not* use the ATF libraries, which is something that
has been frequently requested around here; nor it is possible to attach
arbitrary metadata to test programs from the Makefile, which is handy
particularly for ATF-less test programs.
For these reasons, consider this a transitional step.
Note that, with this change, you should now be able to use the 'kyua'
tool to run the tests in /usr/tests.
Atffile generation.
This is needed to be able to generate Kyuafiles (coming later), as these
clearly differentiate between the definition of test programs and the
recursion into other subdirectories (or files).
In particular: rename ATFFILE_EXTRA_TPS to ATFFILE_EXTRA_SUBDIRS and
change the logic in bsd.test.mk to keep track of subdirectories aside from
_TESTS when creating the Atffile.
The new ATFFILE_EXTRA_TPS variable can hold a set of test programs or
subdirectories to be added to the generated Atffile, without needing these
to be built by the current Makefile.
This is to be used in conjunction with MK* knobs and external/ so that
a 3rd-party component can place its tests in the corresponding tests/
directory and have the parent Atffile recognize them.
An alternative would be to use 'tp-glob' in the Atffile and list the names
of the directories/tests that may or may not exist. However, this would
require providing manually-crafted Atffiles -- and because the majority are
auto-generated, there would be some confusion.
MKKYUA defaults to no and will remain as such until the import is complete
and validated.
This knob does not currently have any effects on the build as nothing relies
on it yet. Upcoming imports and changes in this area will all be guarded by
this flag.
