Date: Thu, 26 Aug 2010 19:58:36 +0000
Subject: [PATCH] Update time zone data files to tzdata release 2010l: DST law
changes in Egypt and Palestine. Added new names for two Micronesian
timezones: Pacific/Chuuk is now preferred over Pacific/Truk (and the
preferred abbreviation is CHUT not TRUT) and Pacific/Pohnpei is preferred
over Pacific/Ponape. Historical corrections for Finland.
