Install the systemd_timesyncd Service
Description
The systemd_timesyncd service should be installed.
Rationale
Time synchronization (using NTP) is required by almost all network and administrative tasks (syslog, cryptographic based services (authentication, etc.), etc.). systemd_timesyncd is a part of the systemd suite and acts as a NTP client.

The following script can be run on the host to remediate the issue.

else
>&2 echo 'Remediation is not applicable, nothing was done'
fi
