I have a question regarding the =E2=80=9CLeap Status=E2=80=9D 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
