systemd-timesyncd is a daemon that has been added for synchronizing the system clock across the network
systemd-timesyncd needs to be enabled and running in order to synchronize the system to a timeserver.
Time synchronization is important to support time sensitive security mechanisms and to ensure log files have consistent time records across the enterprise to aid in forensic investigations
Run the following command to verify that the systemd-timesyncd service is enabled:
# systemctl is-enabled systemd-timesyncd.service
Output:
enabled
Run the following command to verify that the systemd-timesyncd service is active:
# systemctl is-active systemd-timesyncd.service
Output:
active
Run the following command to unmask systemd-timesyncd.service:
# systemctl unmask systemd-timesyncd.service
Run the following command to enable and start systemd-timesyncd.service:
# systemctl --now enable systemd-timesyncd.service
- OR -
If another time synchronization service is in use on the system, run the following command to stop and mask systemd-timesyncd:
# systemctl --now mask systemd-timesyncd.service
