** Fix for bug #351932
2007-11-05 Milan Crha <mcrha@redhat.com> ** Fix for bug #351932 * widgets/misc/e-dateedit.h: (e_date_edit_have_time): * widgets/misc/e-dateedit.c: (e_date_edit_have_time): Extend API to be able to check if time is set independently of date part. * calendar/gui/dialogs/task-page.c: (check_start_before_end), (times_updated), (start_date_changed_cb), (due_date_changed_cb), (init_widgets): Ensure due date is not before start date. svn path=/trunk/; revision=34500
