+If you press 'X' you can scroll down to NTP Server 2 and change that in the same manner.

+Restart the NTP server by either performing a reboot, or using the following command from the SSH terminal.
+    systemctl restart ntpd
+\\
+To check that NTP is working, you can perform this command from the SSH terminal:
+    ntpstat
+You should see something similar to below:

+synchronised to NTP server (162.159.200.123) at stratum 4

+==== Under the Hood ====
+In linux (Centos or Alma) there is a file in /etc called ntp.conf, by default, it will list four NTP public sources:
+(cat or edit /etc/ntp.conf to see this)
+In the ntp.conf you will see the following four lines (as long as it has never been edited)
+<file>
+# Use public servers from the pool.ntp.org project.
+# Please consider joining the pool (http://www.pool.ntp.org/join.html).
+server 0.centos.pool.ntp.org iburst
+server 1.centos.pool.ntp.org iburst
+server 2.centos.pool.ntp.org iburst
+server 3.centos.pool.ntp.org iburst
+</file>
+When you enable NTP from the front panel (virtual or physical) then you will see the IP Addresses that you entered in this file, and there will only be 2 lines of servers. (Because the front panel only allows you to enter two NTP IP addresses).
+<file>
+# Use public servers from the pool.ntp.org project.
+# Please consider joining the pool (http://www.pool.ntp.org/join.html).
+server 162.159.200.123 iburst
+server 51.89.151.183 iburst
+</file>
+\\
+There are two important considerations here:
+\\
+. You cannot enter DNS names for NTP Servers from the front panel (IP Addresses only)
+. The front panel cannot show you the NTP Address if you are using DNS Names.
+\\
+You can edit the /etc/ntp.conf file and enter DNS names for NTP servers, this just will not be reflected in the front panel, and you have to edit /etc/ntp.conf manually.
