+Backported upstream patch to move the time zone fix in icaltimezone_get_utc_offset over
+to icaltimezone_get_utc_offset_of_utc_time. r1141 made a fix in the first function but not
+the second. This ensures these almost identical methods behave almost identically :) See
+http://sourceforge.net/p/freeassociation/code/1150/ for the upstream patch and also Red Hat
+Bugzilla at https://bugzilla.redhat.com/show_bug.cgi?id=1021136
