+
+ * 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.
