Network Time Protocol (SNTP) to get the current time from an SNTP server
outside your network. Choose your local time zone. After a successful connection
to the Internet, the router will retrieve the correct local time from the SNTP server
you have specified. If you prefer to specify an SNTP server other than those in
the drop-down list, simply enter its IP address as shown above. Your ISP may
provide an SNTP server for you to use.
Time Server:
Use Time Server when Bootup: Select the time service protocol that your time
server sends when you turn on the Router. Not all time servers support all
protocols, so you may have to check with your ISP/network administrator or use
trial and error to find a protocol that works. The main difference between them is
the format.
Daytime (RFC 867) format is day/month/year/time zone of the server.
Time (RFC 868) format displays a 4-byte integer giving the total number of
seconds since 1970/1/1 at 0:0:0.
The default, NTP (RFC 1305), is similar to Time (RFC 868).
Select None to enter the time and date manually.
