Douglas, Well' I'll be darned. I had no idea that the GPS receiver display could be off by seconds. I naturally thought that, with atomic clocks onboard the satellites, the receivers would be displaying atomic-clock accuracy. Thanks for setting me straight. Actually, I have been checking my Timex against a small WWVB clock which receives 60Khz time signals from near Fort Collins, Colorado. Does anyone know how this 60Khz signal strength is world wide?? There's also the NIST website at http://nist.time.gov/timezone.cgi?Central/d/-6/java which claims 0.2 second accuracy. Is that accuracy statement reliable??
