Users can also check the status of the time scale to ensure the UTC offset value [ptd] is under +/-
100 ns from UTC and the clock is being steered

Users may use the
jam_
sync command to synchronize the system 1 PPS to the reference input.

Then use the
status kas2
command to ensure the internal clock offset has jumped to the reference.

Note:
Using the
jam_sync
command will cause the internal clock to steer very hard in order to
synchronize with the external reference.
6.2.5 External Reference
If you suspect there may be issues with the external reference use the
status health
and
status
oscillator
commands to look at the status of the external reference and internal clocks.
