In order to achieve millisecond resolution on the mac you either need
to grab one of the VIA's timers and use that, or use the Time Manager
and set an interrupt to happen periodically (in this case every 1 ms)
If your application will run under multifinder then you need to watch
out for other things which might also use the VIA's timers (eg. sound
and disk accesses). In any case this can be somewhat tricky to do.
Hope this helps a little. :)
