I don't know about accuracy, but I noticed something funny last week while running a program.
I have a program which communicates over RS-232 and I need to make pauses now and then. After sending a few commands, I set the VI to wait for 20 minutes (1200000 ms). If I call the 20 minutes, half the time the VI freezes, it never re-starts. If I make a smaller wait first, it works fine. Even subsequent calls for 1200000 ms work fine. I don't have an explanation for this, but it seems something wierd is going on. I'm using W2k, LV 6.1. Hope this helps shane.
