The following table describes the fields in this screen.
Table 239 Menu 24.10 System Maintenance: Time and Date Setting
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
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
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-
nth-week-hr)
Configure the day and time when Daylight Saving Time starts if you selected Yes
in 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).
End Date (mm-
nth-week-hr)
Configure the day and time when Daylight Saving Time ends if you selected Yes in
the Daylight Saving field. The hr field uses the 24 hour format. Here are a couple
of examples:
Daylight Saving Time ends in the United States on the last Sunday of October.
Each time zone in the United States stops using Daylight Saving Time at 2 A.M.
local time. So in the United States you would select Oct., Last, Sun. and type 02 in
the hr field.
Daylight Saving Time ends in the European Union on the last Sunday of October.
All of the time zones in the European Union stop using Daylight Saving Time at the
same moment (1 A.M. GMT or UTC). So in the European Union you would select
Oct., 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).
