	No, there is no more precise date/timer which return
	hour,minutes,seconds.
	But you can the 200Hz Timer (=5ms) to measure small
	durations. There is a long value at address 1210 which
	is being incremented 200 times per second since system boot.
	(counting 5ms ticks). You must be in super mode to read
	this value.

	Maybe this will help you
