>>>Not overhead, but quite a bit of coding. Can you explain what is supposed to be the problem if I just set the timer, say, to 2 hours (2 * 3600 * 1000)? You mention accuracy, but doesn't the timer automatically check, at regular intervals, whether the specified time elapsed?

>>What if you check every two hours, and the timer was supposed to run an hour and 45 minutes ago? Then accuracy is lost anyways.

When the time expires while some OTHER (non-VFP) process is running.
