Table 22 Time and Date
LABEL DESCRIPTION
Time Server
Use Protocol when
Bootup
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.
NTP (RFC 1305) is similar to Time (RFC 868).
Select None to enter the time and date manually.
IP Address or URL Enter the IP address or URL of your time server. Check with your ISP/network
administrator if you are unsure of this information.
Time and Date Choose the time zone of your location. This will set the time difference between
your time zone and Greenwich Mean Time (GMT).
Daylight Savings Select this option if you use daylight savings time. 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.
Start Date Enter the month and day that your daylight-savings time starts on if you selected
Daylight Savings.
End Date Enter the month and day that your daylight-savings time ends on if you selected
Daylight Savings.
Synchronize
system clock with
Time Server now.
Select this option to have your ZyXEL Device use the time server (that you
configured above) to set its internal system clock.
Please wait for up to 60 seconds while the ZyXEL Device locates the time server.
If the ZyXEL Device cannot find the time server, please check the time server
protocol and its IP address. If the IP address was entered correctly, try pinging it
for example to test the connection.
