Enable Network Time Protocol Client
When selected, the server obtains the current date and time from the NTP servers listed in the NTP Servers list below. The server uses the date and time supplied and makes regular NTP requests for updates.
NTP Servers:
With Enable Network Time Protocol Client selected, use this field to enter the IP address of an NTP server or servers to use. Enter each address as a separate line. The network administrator or ISP may have an NTP server for this purpose.
A list of publicly accessible NTP servers is available at http://support.ntp.org/bin/view/Servers/WebHome. However, it is your responsibility to comply with the usage policy of the chosen server.
Choose several NTP servers in case one of the NTP servers becomes unreachable or unreliable. The server uses the responses it receives from each NTP server to determine reliability.
