12 ntpstat will report the synchronisation state of the NTP daemon (ntpd)
13 running on the local machine. If the local system is found to be syn‐
14 chronised to a reference time source, ntpstat will report the approxi‐
15 mate time accuracy.
16
17 When the synchronised state is reported, it means the system clock was
18 updated at some point. There is no timeout for this state. It will
19 stay there even when the source becomes unreachable and there are no
20 other sources available. However, the reported accuracy will be slowly
21 increasing, in the default ntpd configuration by 15 microseconds per
22 second.

26 ntpstat returns 0 if clock is synchronised. ntpstat returns 1 if clock
27 is not synchronised. ntpstat returns 2 if clock state is indetermi‐
28 nant, for example if ntpd is not contactable.
