Note: If you enter time settings manually, they revert to their
defaults when power is lost.

Select this radio button to have the ZyXEL Device get the time and date from the
time server you specified below.
The ZyXEL Device requests time and date settings from the time server under the
following circumstances.
• When the ZyXEL Device starts up.
• When you click Apply in the Time Setting screen.
• 24-hour intervals after starting up.
Time Protocol Select the time service protocol that your time server uses. 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).

your time server. Check with your ISP/network administrator if you are unsure of
this information.
