It is the smallest non-zero difference between two readings of the 
clock.  If the clock is very high resolution, it may be close to the 
time to read the clock.  If the clock is low resolution, it is 
determined by the resolution of the clock.

If the clock can only be read to 10ms (no interpolation) you can expect 
multiple reads.
