DESCRIPTION

Time Server

 

 

 

Use Protocol

Select the time service protocol that your time server uses. Not all time servers

when Bootup

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.

 

When you select the Daytime (RFC 867) format, the switch displays the day,

 

month, year and time with no time zone adjustment. When you use this format it

 

is recommended that you use a Daytime timeserver within your geographical time

 

zone.

 

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

Select this option to have your ZyXEL Device use the time server (that you

system clock with

configured above) to set its internal system clock.

Time Server now.

Please wait for up to 60 seconds while the ZyXEL Device locates the time server.

protocol and its IP address. If the IP address was entered correctly, try pinging it

 

for example to test the connection.
