I found that they all have inaccurate clocks. Some run fast and some run slow. Each one is different. I wrote some automatic corrrection code into my program. I found that even the ammount of error varied over time on the same machine. I have to set the time at least once a week to maintain accuracy to within a couple of minutes. I'm afraid that if you need extreme accuracy over a long period of time, the only answer will be a hardware clock. Joel Swank Tektronix, Beaverton OR
