9.2 NTP
The Network Time Protocol (NTP) is a protocol used to receive time from a configured
server and synchronize the local time.
The APC can operate as a NTP server and a client. If you configure the APC as a NTP
client, it receives the Coordinated Universal Time (UTC) information from the configured
NTP server and synchronizes the local time. In addition, if you configure the APC as a NTP
server, it transmits a local time when it receives a NTP request from a NTP client.
Configuration using CLI
[Configuring NTP Client]
The time server that is referred to when the APC is working as a NTP client can be used
based on a domain name and IP address. But, if it is working based on a domain name,
there must be a configured DNS server.
