Table 218   Menu 24.10 System Maintenance: Time and Date Setting

Time Protocol

Enter the time service protocol that your timeserver 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 

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.
The default, NTP (RFC-1305), is similar to Time (RFC-868).
Select Manual to enter the new time and new date manually.

Time Server 

Address

Enter the IP address or domain name of your timeserver. 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. This field is available when 

you select Manual in the Time Protocol field.

Current Date

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

New Date

Enter the new date in year, month and day format. This field is available when you

Time Zone

Press [SPACE BAR] and then [ENTER] to set the time difference between your 

time zone and Greenwich Mean Time (GMT). 

Daylight Saving

Daylight Saving Time 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 daylight time in 

the evenings. If you use daylight savings time, then choose Yes.
