[chrony-users] [Question] chronyc tracking shows large offset

[zc z <zzc8573@xxxxxxxxx>]

version: chrony 4.4

OS: Ubuntu 18.04

I have a question regarding the “Leap Status” field in the chronyc -n tracking command.

My chrony.conf configuration is as follows:

server 192.168.46.99 iburst minpoll 2 maxpoll 2

driftfile /var/lib/chrony/drift

makestep 0.05 3

maxdistance 1.6

I ran a script to record chronyc -n tracking output every 5 seconds. When I unplugged the network cable and waited for 20 hours, I observed that the Leap Status remained Normal. At that time, the rootdelay was 1.00000238 ms and root dispersion was 1.338544011 s. The accumulated estimated error exceeded 1.6 seconds (maxdistance), yet the Leap Status did not change to Not synchronized.

Could you please clarify why the Leap Status remains Normal under these conditions? How long does it take for the Leap Status to change, or how can I configure it to detect anomalies, such as a network disconnection, and switch to Not synchronized?

Thank you for your help.

Best regards
