The digital wall clock needs to know the DNS name or IP address of the NTP time server that the clock is to synchronise to. This can be acheived by logging on to the clock via a telnet session and using the 'sntp' command to modify the time server settings.
After logging on to the clock using a telnet client, set the time server address by:
sntp -h xxx.xxx.xxx.xxx
or alternatively,
sntp -h hostname
Where xxx.xxx.xxx.xxx is the IP address of the specified NTP server.
Where hostname is the hostname of the specified NTP server.
