FIELD

DESCRIPTION

 

 

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

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

Address

network administrator if you are unsure of this information. The default is

 

tick.stdtime.gov.tw

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

 

select Manual in the Time Protocol field.

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.

Start Date (mm-

Configure the day and time when Daylight Saving Time starts if you selected Yes in

nth-week-hr)

the Daylight Saving field. The hr field uses the 24 hour format. Here are a couple

 

of examples:

 

Daylight Saving Time starts in most parts of the United States on the first Sunday of

 

April. Each time zone in the United States starts using Daylight Saving Time at 2

 

A.M. local time. So in the United States you would select Apr., 1st, Sun. and type

 

02 in the hr field.

 

Daylight Saving Time starts in the European Union on the last Sunday of March. All

 

of the time zones in the European Union start using Daylight Saving Time at the

 

same moment (1 A.M. GMT or UTC). So in the European Union you would select

 

Mar., Last, Sun. The time you type in the hr field depends on your time zone. In

 

Germany for instance, you would type 02 because Germany's time zone is one

 

hour ahead of GMT or UTC (GMT+1).
