2001-08-31  Damon Chaplin  <damon@ximian.com>

	* zoneinfo/*: updated all of the VTIMEZONE files to try to be more
	compatable with Outlook. i.e. We don't use seconds in UTC offsets,
	we don't use BYMONTHDAY if we can avoid it (there are still a few uses
	of this we need to fix), and we don't use years < 1600.

	* src/libical/icalvalue.c (icalvalue_utcoffset_as_ical_string): if
	seconds is 0 then don't output it. None of the builtin VTIMEZONE data
	uses the seconds value any more, since it messes up iTIP with Outlook.
	We may want to make it always round to the nearest minute, to avoid
	interop problems.
