Timer off system clock

Hi there,

I've seen it mentioned, but not implemented that a timer in excel could be set off the system clock? Is there a way to do this so that a VBA program running off the timer would run at a consistent speed on different machines?

Thanks

That schedules procedures to run based on the clock. I'm looking for a timer that counts in real time based on the clock. So that an equation using the cell with the timer will run in real time?

vba start button (Stamps start time), vba stop button (Stamps end time), the system clock is the timer, simple, then deduct finish from start = time
