Type Duration has a small 'small, but the Windows Performance Counter
only ticks (approximately) every 1/nth of a microsecond, where n = 3 on
the machine I'm using now. So two successive clock reads, if they don't
give the same value, will differ at least by 300 or so nanoseconds.
You may want to look up "Time the Clock" on AdaPower.
