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.
