How do I know if NTP is installed Linux?

The ntpstat command will report the synchronisation state of the NTP daemon running on the local machine.

exit status of ntpstat command

  1. If exit status 0 – Clock is synchronised.
  2. exit status 1 – Clock is not synchronised.
  3. exit status 2 – If clock state is indeterminant, for example if ntpd is not contactable.
