The Chronyd service is enabled

An XCCDF Rule

Description

chrony is a daemon which implements the Network Time Protocol (NTP) is designed to synchronize system clocks across a variety of systems and use a source that is highly accurate. More information on chrony can be found at http://chrony.tuxfamily.org/. Chrony can be configured to be a client and/or a server. To enable Chronyd service, you can run: # systemctl enable chronyd.service This recommendation only applies if chrony is in use on the system.

Rationale

If chrony is in use on the system proper configuration is vital to ensuring time synchronization is working properly.
