Nor do I understand it. The internet could go on working if no two clocks agreed to within a minute. This is NOT the case with frequencies however! The technology uses time division multiplexing which requires precise clocking in order to figure out which bit is which. This does not require absolute time; only delta time. The clock must tick exactly at the top of the microsecond but nobody cares if it's 6:00PM or 6:01PM. _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
