Now GetTime() works as intended, except every second or two I get a strange (really large) value returned. Any ideas?

BTW: I discovered this error around 3:00am on ship day, which was wreaking havoc on our autonomuous code. Without a controller to test on, I haven't been able to trace the problem.

YOU SHIPPED YOUR CONTROLLER?!?!? You still have your EDU, right?

In GetTick(), why not just set Timer_Snapshot to tmsClock? Doesn't the interupt go off every tick? or just on overflow?
