2001-10-21  JP Rosevear  <jpr@ximian.com>

	* gui/dialogs/schedule-page.c (init_widgets): listen for changes
	in the date editors
	(schedule_page_set_dates): update the times when they change
	elsewhere
	(update_time): set the time in the dialog
	(time_changed_cb): notify of changed times

	* gui/dialogs/comp-editor.c (page_dates_changed_cb): don't call
	the set dates function on the page that noted the change
	(page_summary_changed_cb): same for set summary function

	* gui/dialogs/event-page.c (update_time): move time setting stuff
	to util function
	(event_page_set_dates): use it
