** Fix for bug #238346

	** Fix for bug #238346

	* gui/e-calendar-view.c: (e_calendar_view_add_event): Keep old
	timezone when adding event if possible, use the default one otherwise.
	* gui/e-calendar-view.c: (add_related_timezones), (clipboard_get_text_cb):
	Set timezones from component to the calendar first, then add events. Also
	fetch timezones from the calendar, when not part of the component already.
