save the EXDATE as a DATE-TIME value, since we know the exact time. Fixes
2001-10-03 Damon Chaplin <damon@ximian.com> * gui/comp-util.c (cal_comp_util_add_exdate): save the EXDATE as a DATE-TIME value, since we know the exact time. Fixes bug #11278. (Before we were setting is_date, but icaltime_from_timet_with_zone() didn't convert it properly. We need to figure out how to handle DATEs when using time_t's.) * gui/dialogs/recurrence-page.c (get_exception_string): use e_time_format_date_and_time() so we show the time as well, if the exception is a DATE-TIME value. * cal-util/timeutil.c: removed time_add_month(), time_year_begin(), time_month_begin() & time_week_begin() - old pre-timezone functions which we no longer use. * cal-util/cal-recur.c (cal_recur_from_icalproperty): set ir.until.is_date to FALSE before converting to a time_t. Hopefully fixes bug #5034. svn path=/trunk/; revision=13366
