And if I have read the history correctly the deployment of cesium standards along the LORAN-C chains in the late 1960s was one of the strongest motivating forces for the CCIR's unilateral and urgent action to change the standard for broadcast time signals from following the earth rotation measure that they explicitly identified by name as UT2 to following the atomic time measure (which was about to be named TAI) with added leap seconds. -- Steve Allen <s...@ucolick.org> WGS-84 (GPS) UCO/Lick Observatory Natural Sciences II, Room 165 Lat +36.99855 University of California Voice: +1 831 459 3046 Lng -122.06015 Santa Cruz, CA 95064 http://www.ucolick.org/~sla/ Hgt +250 m _______________________________________________ LEAPSECS mailing list LEAPSECS@leapsecond.com http://six.pairlist.net/mailman/listinfo/leapsecs
