This exactly matches what you propose above. Your fist step is "figure outexactly what the rate of the clock is" How can you measure the clock's rate to a precision of one second per day unless you wait one day or can read the time to less than than one second? So my 24 hour estimate of the time required to wait uses your method and assumes you do it perfectly, without error. Yes NTP will "jump" the clock if the error is over 125 mS but in this context 125Ms error is "way huge". It is at least two orders of magnitude over what NTP can do even in a very simple setup. Jumping like that would only happen after along a period of being disconnected from a reference clock. -- Chris Albertson Redondo Beach, California _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
