FIELD DESCRIPTION
Time Protocol You can update the current date and time manually, or the ZyXEL Device can
synchronize with a time server.
Manual means you update the current date and time manually.
If the ZyXEL Device synchronizes with a time server, 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).
Time Server Address Enter the IP address or URL (up to 20 extended ASCII characters in length) of
your time server. Check with your ISP/network administrator if you are unsure
of this information.
Current Time This field displays the current time in the ZyXEL Device.
New Time (hh:mm:ss) This field displays the last updated time from the time server or the time you
opened this menu. Enter the new time in this field.
Current Date This field displays the current date in the ZyXEL Device.
New Date (yyyy-mm-
dd)
This field displays the last updated date from the time server or the time you
opened this menu. Enter the new date in this field.
Time Zone Choose the time zone of your location. This will set the time difference between
your time zone and Greenwich Mean Time (GMT).
Daylight Saving Daylight saving is a period from late spring to early fall when many countries
set their clocks ahead of normal local time by one hour to give more daytime
light in the evening.
Select this option if you use Daylight Saving Time.
