Use the ntp command to identify the NTP (Network Time Protocol) server. After
identifying an NTP server, the appliance functions as a Simple Network Time
Protocol (SNTP) client as described in RFC 2030.

server. Although the CLI supports only one NTP server, you can use the
WebGUI to identify multiple NTP servers. When more than one NTP server
is identified, the appliance contacts the first NTP server in the list. If this
server does not respond, the appliance contacts the next server in the list. If
you used the WebGUI to identify more than one NTP server, do not use the
CLI to modify the NTP service. Using the ntp command replaces the entire
list with the one identified NTP server.
