- On most modern macs, the "TickCount" clock has nothing to do with video
- update, but it still works at approximately 60 ticks per second. It does
- skip ticks when there are a lot of interrupts (like LocalTalk activity),
- so it's not advisable to use the tick clock for accurate timing.
-
- The Time Manager provides drift-free millisecond and microsecond timers
- and should be much better suited for timing tasks once you learn how to
- use it.
