>> Is there a way to have ntpd ignore the PPS quickly if it spins out of control? The system recovers fairly quickly and the clock doesn't go too far out but it would be nice to avoid these jumps.
I realize now that I didn't respond to the question :-( . AFIK there are no knobs available to do this. It would be nice to be able to specify maximum acceptable offset or jitter by clock.
