23.2  Time and Date Setting

 The ZyXEL Device keeps track of the time and date. There is also a software mechanism to 
set the time manually or get the current time and date from an external server when you turn 
on your ZyXEL Device. Menu 24.10 allows you to update the time and date settings of your 
ZyXEL Device.

 

The updated time is then displayed in

 

the ZyXEL Device error logs. 

1

Select menu 24 in the main menu to open 

Menu 24 – System Maintenance

.  

2

Then enter 10 to go to 

Menu 24.10 – System Maintenance – Time and Date Setting

 to 

update the time and date settings of your ZyXEL Device as shown in the following 
screen.

System Maintenance: Time and Date Setting

FIELD

DESCRIPTION

Time Protocol

Enter the time service protocol that your time server sends when you turn on 

the ZyXEL Device. 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 differences between them are 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)

.

None

. The default, enter the time manually.

Time Server Address

Enter the IP address or domain name of your time server. Check with your ISP/

network administrator if you are unsure of this information.

Current Time

This field displays an updated time only when you reenter this menu.

New Time

Enter the new time in hour, minute and second format.

Current Date

This field displays an updated date only when you re-enter this menu.
