added setDefaultTimezone() method.

2001-10-22  Damon Chaplin  <damon@ximian.com>

	* idl/evolution-calendar.idl: added setDefaultTimezone() method.

	* pcs/cal-backend.c (cal_backend_get_default_timezone):
	(cal_backend_set_default_timezone): new functions to call class
	methods.

	* pcs/cal-backend-file.c: lots of changes to handle the default
	timezone and use it.

	* pcs/query.c: use the default timezone.

	* gui/dialogs/task-details-page.c (date_changed_cb): initialized
	completed_tt.

	* gui/dialogs/event-page.c: changed it to handle DATE values. The
	'All Day Event' checkbox is only set now when the DTSTART and DTEND
	are DATE values.

	* gui/dialogs/comp-editor-util.c (comp_editor_free_dates): free the
	CalComponentDateTime structs as well.

	* gui/e-tasks.c: set the default timezone on the server.

	* gui/tag-calendar.c:
	* gui/gnome-cal.c:
	* gui/e-week-view.c:
	* gui/e-day-view.c: updates to handle DATE values.

	* gui/e-calendar-table.c (date_compare_cb): updated to use the new
	ECellDateEditValue values, so it now works.
	(percent_compare_cb): updated to use GPOINTER_TO_INT values.
	(e_calendar_table_init): use an ECellPercent for the percent field
	and an ECellDateEditText for the date fields.

	* gui/comp-util.c (cal_comp_util_compare_event_timezones): return TRUE
	if the DTSTART or DTEND is a DATE value. We don't want to show the
	timezone icons for DATE values.

	* gui/comp-editor-factory.c (resolve_pending_requests): set the default
	timezone on the server.

	* gui/calendar-model.c: major changes to support sorting properly.
	For date and percent fields we now use subclasses of ECellText, so
	we don't use a char* as the model value. For the percent field we now
	use a GINT_TO_POINTER. For the date fields we now use a
	ECellDateEditValue* as the value.

	* gui/calendar-config.c (calendar_config_configure_e_cell_date_edit):
	set the timezone and use_24_hour flags of the new ECellDateEditText.

	* conduits/todo/todo-conduit.c (pre_sync):
	* conduits/calendar/calendar-conduit.c (pre_sync): set the default
	timezone on the server.

	* cal-util/timeutil.c (time_days_in_month): removed debug message.

	* cal-util/test-recur.c: try to handle timezones in the iCalendar
	file properly, and updated to pass default timezone.

	* cal-util/cal-util.c (cal_util_generate_alarms_for_comp):
	(cal_util_generate_alarms_for_list): added default timezone argument.

	* cal-util/cal-recur.c: changed many of the functions to take a default
	timezone, to use to resolve DATE and floating DATE-TIME values.

	* cal-client/cal-client.c (cal_client_set_default_timezone): new
	function to set the default timezone.
	(cal_client_ensure_timezone_on_server): new function to ensure that
	a given timezone is on the server.

	* gui/e-cell-date-edit-text.c: new subclass of ECellText to display
	and edit a date value.

	* cal-util/cal-recur.c (cal_obj_byday_expand_monthly): changed week_num
	to -week_num when calculating the weeks to go back from the end of the
	month for things like BYDAY=-2WE. Fixes bug #11525.
	(cal_recur_generate_instances_of_rule): only go up to MAX_YEAR (2037).
	We can't really handle anything past that anyway.
	(cal_recur_ensure_rule_end_date): initialize cb_date.end_date to 0,
	so if the RULE doesn't generate COUNT instances we save 0 as the
	time_t.
