updated all files again, placing current RDATEs first, so Outlook uses

2001-10-22  Damon Chaplin  <damon@ximian.com>

	* zoneinfo/*: updated all files again, placing current RDATEs first,
	so Outlook uses those. Also fixed a few bugs in vzic which resulted in
	a few changes.

	* zoneinfo/Makefile.am (DIRS): added America/North_Dakota.

2001-10-22  Damon Chaplin  <damon@ximian.com>

	* src/libical/icaltimezone.c (icaltimezone_get_utc_offset):
	(icaltimezone_get_utc_offset_of_utc_time): if we go off the start of
	the changes array, return the TZOFFSETFROM of the first change.
	Also changed the maximum year to 2037.

	* src/libical/icaltime.c (icaltime_day_of_week):
	(icaltime_start_doy_of_week):
	(icaltime_week_number): init tm_hour to 12. Sometimes mktime()
	adjusts the time, if that local time doesn't actually exist, leading
	to the wrong day being returned. It is unlikely to adjust by 12 hours.
	(icaltime_as_timet_with_zone):
	(icaltime_from_timet_with_zone): change it back so it does convert
	DATE values to/from the timezone. time_t values don't really go well
	with DATE values, so be very careful when using them. We now assume
	that the time_t points to the start of the day in the given timezone.
	(We used to assume it pointed to the start of the day in UTC, but
	that meant it was actually incorrect wrt the displayed calendar.)

	* src/libical/icalrecur.c (expand_year_days): for FREQ=YEARLY with no
	modifiers, we add one day, using the month and day from DTSTART.
	(next_year): make sure we never go past 2037.

	* scripts/mkderivedproperties.pl: Updated to allow DTSTART, DTEND, DUE
	and RECURRENCE-ID to be set with DATE values. I think it now handles
	all properties which can take DATE values, except RDATE which uses
	DATE-TIME-PERIOD.
