I cannot recall seeing this topic come up, but if it did, please point me to the archived discussion. For our sailing races, we have just changed to a system that relies on the so-called "atomic clocks" that are now sold ubiquitously. Such clocks, as I understand it, are quartz based and are periodically reset by directly "listening" to WWV. What we tell the racers at the skippers meeting is: Just use time on your GPS. The question is whether there is a 1-2 sec discrepancy between WWV (NBS) time and that shown on ones GPS receiver. A couple of us think that we have noted this discrepancy. What say ye? Any comments including who to contact at WWV in this regard will be appreciated. Robert Block S/Y Connemara Santa Barbara
