13.3.7. Manually Adjusting the System Clock
To update, or step, the system clock immediately, bypassing any adjustments in progress by slewing the clock, issue the following commands as
root
:
~]# chronyc
chrony> password
commandkey-password
200 OK
chrony> makestep
200 OK
Where
commandkey-password is the command key or password stored in the key file.
The real-time clock should not be manually adjusted if the rtcfile
directive is used as this would interfere with chrony's need to measure the rate at which the real-time clock drifts if it was adjusted at random intervals.
If
chronyc is used to configure the local
chronyd, the
-a
will run the
authhash
and
password
commands automatically. This means that the interactive session illustrated above can be replaced by:
chronyc -a makestep
