Most of the "atomic" radio-controlled clocks in the US do exactly the same sort of jump every night when the ionosphere lets the signal from WWVB come through clearly. And in Japan, since the main transmitter for JJY is within the Fukushima evacuation zone, such watches have presumably been freerunning and accumulating errors without resets ever since the earthquake. -- Steve Allen <[email protected]> WGS-84 (GPS) UCO/Lick Observatory--ISB Natural Sciences II, Room 165 Lat +36.99855 1156 High Street Voice: +1 831 459 3046 Lng -122.06015 Santa Cruz, CA 95064 http://www.ucolick.org/~sla/ Hgt +250 m _______________________________________________ LEAPSECS mailing list [email protected] http://six.pairlist.net/mailman/listinfo/leapsecs
