There is no single answer to this. One man's high-performance is another man's low-performance. It all depends on where you are in your quest. > Some of the self build units I've heard being used can be 100 to 1000 or more > times worse than desired for best performance. > > WarrenS That is correct. Because time can be measured more precisely than any other physical quantities it is quite normal for amateur projects or even professional products to span many orders of magnitude in performance. It is also true that the requirements have as great a span. Someone needing a time source simply for NTP (milliseconds) can get by with a solution a million times less precise than someone trying to tune the C-field of their own cesium standard (nanoseconds). /tvb _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
