[evolution-patches] fix for bug #42045

[Jeffrey Stedfast <fejj ximian com>]

stupid lame-arsed mailer is sending:

Date: Tue, 29 Apr 2003 13:50:51 359500

so Evolution is using '359500' as the timezone offset and getting a
completely bogus date.

my patch just makes sure the tzone is between -1200 and 1200, if it's
not, then we ignore the timezone token.

Jeff
