2000-09-20  JP Rosevear  <jpr@helixcode.com>

	* conduits/todo/todo-conduit.h: Add since field to context

	* conduits/todo/todo-conduit.c (map_set_node_timet): New utility
	function
	(map_sax_start_element): Look for the map timestamp as well
	(map_write): Write the map timestamp
	(pre_sync): Use the map time stamp when looking for changed entries

	* pcs/cal-backend.c (cal_backend_log_sax_start_element): Make sure
	we are in a valid timestamp
