Hi @davidyang429 ,

ntplib is designed to be an implementation of the ntp protocol.
But this ntp synchronised status is not part of the ntp protocol, it's implemented by the ntp client/daemon, and is actually quite complex (dealing with outliers, etc).
So there is no access to this status from ntplib - which queries a single server btw.

Depending on what you are trying to achieve, you might get away which just checking that the offset is lower than an hard-coded threshold but it's probably fragile: I guess that if you just want this status you might have to query whatever client your machine is using.

Cheers,
