I honestly don't know. The tick counter is reset anytime the computer is
restarted, or if the value rolls over, which happens in systems that are
on for very long periods of time. The attempt is to generate a tick
every millisecond, but in practice the general indication is that it's
"close" to that.
I'm just curious, what on earth requires you to explore such fine
elapses of time?
Good luck,
