No idea. It looks random to me. I think it should be just output of a high-pass filter of changes in the clock frequency. > How long is the typical time scale over which chrony keeps the data to fit the > linear regression to? What is the polling period? Polling interval was fixed to 64 seconds, the number of samples is around 30-40. With higher jitter or more stable clock (longer Allan intercept) the number of samples would be higher. -- Miroslav Lichvar --- To unsubscribe email chrony-dev-requ...@chrony.tuxfamily.org with "unsubscribe" in the subject.
