I am a bit confused. I thought that chrony delivered its best estimate of the time now, which might be different from the time actually shown by the system clock, because it was still in the process of being corrected. So, if it decided that the time, from the best fit, now was 12:00:00.

I guess most people here don't follow the NTP WG list. There is one feature proposed for NTPv5 that I think would make a big difference for chrony: https://fedorapeople.org/~mlichvar/ntp-freq-transfer/ -- Miroslav Lichvar -- To unsubscribe email chrony-dev-requ...@chrony.tuxfamily.org with
