tzdb Release 2012j

Changelog (from NEWS)

Libya moved to CET this weekend, but with DST planned next year.
  (Thanks to Even Scharning, Steffen Thorsen, and Tim Parenti.)

  Signatures now have the extension .asc, not .sign, as that's more
  standard.  (Thanks to Phil Pennock.)

  The output of 'zdump --version', and of 'zic --version', now
  uses a format that is more typical for --version.
  (Thanks to Joseph S. Myers.)

  The output of 'tzselect --help', 'zdump --help', and 'zic --help'
  now uses tz@iana.org rather than the old elsie address.

  zic -v now complains about abbreviations that are less than 3
  or more than 6 characters, as per POSIX.  Formerly, it checked
  for abbreviations that were more than 3.

  'make public' no longer puts its temporary directory under /tmp,
  and uses the just-built zic rather than the system zic.

  Various fixes to documentation and commentary.
