My question re the original post remains: do these devices use a
hardware interrupt line to do a pps? Yes they do. (well, I don't see how else it would be done with any reasonable accuracy).
Same as NTP. Determine the average. Over the short term, accuracy can be very bad, but good when averaged over the long term. That even applies to electric wall clocks. The power line frequency can drift slightly in the short term, but long term it's very accurate. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
