Hi wasif, Unfortunatly that's almost impossible. Every mote's timer I've seen so far created it's timer on a 32768 Hz crystal. You can get us accuracy using the main clock (usually 4-8-16MHz), but the main clock is usually much more innacurate (especially if it's an RC oscillator), but it's usually enough for short measurements.
