红帽全球峰会2.2. Manually adjusting the system clock
You can manually adjust the system clock.
Procedure
To step the system clock immediately, by passing any adjustments in progress by slewing, enter:
# chronyc makestep
重要
If the rtcfile directive is used, the real-time clock should not be manually adjusted. Random adjustments would interfere with chrony's need to measure the rate at which the real-time clock drifts.
