I have a timeclock app as part of my system. It works great except that, as anyone knows, the clock on a PC is about as reliable as... well you know. Does anyone know of an external or internal clock for a PC that keeps good date and time? I know the old Hays modems had a clock version that plugged into the serial port. I just need the clock with date and time. The PC does the checkin/out with a scanner. I don't want to use an internet app because the PC may not have internet access.

Thanks,
John.
