firewall-cmd --permanent --zone=public --add-port=123/udp; firewall-cmd --reload /etc/chrony.conf: allow 192.0.2.0/24
Machine Connecting to Peer:
/etc/chrony.conf: peer 192.0.2.2
Pushing system time to hardware clock
hwclock -w or hwclock --systohc # Note: This isn't needed on RHEL / CentOS 7 Systems when ntp is turned on. The hardware clock is already set to the system time every 11 minutes.

systemctl restart systemd-timedated.service
