Configure NTP Server in Oracle Linux 9

_______________________________________________________________________________________
NTP stands for Network Time Protocol.
It is used to synchronize the time on your Linux system with a centralized NTP server.
A local NTP server on the network can be synchronized with an external timing source to keep all the servers in your organization in-sync with an accurate time.

dnf -y install chrony
nano /etc/chrony.conf
change servers to synchronize (replace to your own timezone NTP server)
# need NTP server itself to sync time with other NTP server
#pool 2.centos.pool.ntp.org iburst
pool ntp.nict.jp iburst

# add network range to allow to receive time synchronization requests from NTP Clients
# specify your local network and so on
# if not specified, only localhost is allowed
allow 192.168.1.50/24

systemctl enable --now chronyd ; systemctl restart chronyd ; systemctl status chronyd
