Import tzdata2014g from ftp://ftp.iana.org/tz/releases/tzdata2014g.tar.gz
Summary of changes in tzdata2014g (2014-08-28 12:31:23 -0700):
* Turks & Caicos is switching from US eastern time to UTC-4 year-round,
modeled as a switch from EST/EDT to AST on 2014-11-02 at 02:00.
* Time in Russia or the USSR before 1926 or so has been corrected by
a few seconds for several zones, and a few minutes for
Asia/Yekaterinburg.
* The Portuguese decree of 1911-05-26 took effect on 1912-01-01, not
on the date of the decree. This affects 1911 time stamps in
Africa/Bissau, Africa/Luanda, Atlantic/Azores, and Atlantic/Madeira.
* Lisbon's pre-1912 GMT offset was -0:36:45 (rounded from -0:36:44.68),
not -0:36:32.
* Asia/Dhaka ended DST on 2009-12-31 at 24:00, not 23:59.
* A new file 'backzone' contains data which may appeal to
connoisseurs of old time stamps, although it is out of scope for
the tz database, is often poorly sourced, and contains some data
that is known to be incorrect.
* 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.
* Changes affecting documentation and commentary.

+Contributing to the tz code and data
+
+The time zone database is by no means authoritative: governments
+change timekeeping rules erratically and sometimes with little
+warning, the data entries do not cover all of civil time before
+1970, and undoubtedly errors remain in the code and data. Feel
+free to fill gaps or fix mistakes, and please email improvements
+to tz%iana.org@localhost for use in the future.
+
+To email small changes, please run a POSIX shell command like
+'diff -u old/europe new/europe >myfix.patch', and attach
+myfix.patch to the email.
+
+For more-elaborate changes, please read the Theory file and browse
+the mailing list archives <http://mm.icann.org/pipermail/tz/> for
+examples of patches that tend to work well. Ideally, additions to
+data should contain commentary citing reliable sources as
+justification.
+
+Please submit changes against either the latest release in
+<ftp://ftp.iana.org/tz/> or the master branch of the experimental
+Git repository. If you use Git the following workflow may be helpful:
+
+ * Copy the experimental repository.
+
+ git clone https://github.com/eggert/tz.git
+ cd tz
+
+ * Get current with the master branch.
+
+ git checkout master
+ git pull
+
+ * Switch to a new branch for the changes. Choose a different
+ branch name for each change set.
+
+ git checkout -b mybranch
+
+ * Edit source files. Include commentary that justifies the
+ changes by citing reliable sources.
+
+ * Debug the changes, e.g.:
+
+ make check
+ make install
+ ./zdump -v America/Los_Angeles
+
+ * For each separable change, commit it in the new branch, e.g.:
+
+ git add northamerica
+ git commit
+
+ See recent 'git log' output for the commit-message style.
+
+ * Create patch files 0001-*, 0002-*, ...
+
+ git format-patch master
+
+ * After reviewing the patch files, send the patches to tz%iana.org@localhost
+ for others to review.
+
+ git send-email master
+
+ * Start anew by getting current with the master branch again
+ (the second step above).
+
+Please do not create issues or pull requests on GitHub, as the
+proper procedure for proposing and distributing patches is via
+email as illustrated above.
