Import tzdata2013a from ftp://ftp.iana.org/tz/releases/tzdata2013a.tar.gz

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>.
