added functions to set a callback to get the current time, which is used

2001-07-02  Damon Chaplin  <damon@ximian.com>

	* e-calendar-item.c:
	* e-cell-date-edit.c:
	* e-dateedit.c: added functions to set a callback to get the current
	time, which is used instead of localtime(). We need this as we have to
	use our own timezones.
