Hi Folks:
I'm sure this has been discussed before, probably many times. It seems I can decode to about 2 seconds out from accurate with WWV. But, I found just restarting my computer brings it back. This settles a suspicion that the computer only grabs the time from the on-board-clock on power up. The on-board clock is slightly fast, and the software clock is a bit slow. I don't know what the source of the software clock is, but I doubt it's the CPU clock.
