Hello,=20 I have just upgraded to chrony version 4.6.1 on Debian 13=20 I have noticed my PTP time has not failed, and it appears to be when I = put :=20 refclock PHC /dev/ptp0 poll 0 dpoll 0 tai If I remove tai - I get 37 second offset and Chrony does not sync to = PTP.=20 This is my current config=20 # Include additional configuration confdir /etc/chrony/conf.d sourcedir /etc/chrony/sources.d sourcedir /run/chrony-dhcp # PTP Hardware Clock as main reference refclock PHC /dev/ptp0 poll 0 dpoll 0 tai # Public NTP pool + HE.net as fallback pool pool.ntp.org iburst server clock.sjc.he.net iburst # Allow local LAN access (optional) allow # Drift file driftfile /var/lib/chrony/chrony.drift # Real-time clock sync rtcsync # Step on large offsets only at boot makestep 1 3 # TAI/UTC leap second information leapsectz right/UTC # Hardware timestamping hwtimestamp * logdir /var/log/chrony maxupdateskew 100.0 -=20 I know my PTP can only output TAI - and this seems to be a new issue I = think, as all documentation I can see suggests I am doing things = correctly =E2=80=A6. Can any one please suggest what I might try to resolve this?=20 Thanks in advance,=20 -- To unsubscribe email chrony-users-request-kWFZVVI9zxvPqho9SqqRMmD2FQJk+8+b@public.gmane.org with "unsubscribe" in the subject.
