DESCRIPTION
Choose a descriptive name for identification purposes. This name consists of up to 64
printable characters; spaces are allowed.
Enter the geographic location of your Switch. You can use up to 32 printable ASCII
characters; spaces are allowed.
Enter the name of the person in charge of this Switch. You can use up to 32 printable
ASCII characters; spaces are allowed.
Enter the time service protocol that your timeserver uses. Not all time servers support all
protocols, so you may have to use trial and error to find a protocol that works. The main
differences between them are the time format.
When you select the Daytime (RFC 867) format, the Switch displays the day, month,
year and time with no time zone adjustment. When you use this format it is recommended
that you use a Daytime timeserver within your geographical time zone.
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 is the default value. Enter the time manually. Each time you turn on the Switch, the
time and date will be reset to 1970-1-1 0:0:0.
Enter the IP address of your timeserver. The Switch searches for the timeserver for up to
60 seconds. If you select a timeserver that is unreachable, then this screen will appear
locked for 60 seconds. Please wait.
This field displays the time you open this menu (or refresh the menu).
Enter the new time in hour, minute and second format. The new time then appears in the
Current Time field after you click Apply.
This field displays the date you open this menu.
Enter the new date in year, month and day format. The new date then appears in the
Current Date field after you click Apply.
Select the time difference between UTC (Universal Time Coordinated, formerly known as
GMT, Greenwich Mean Time) and your time zone from the drop-down list box.
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.
Configure the day and time when Daylight Saving Time starts if you selected Daylight
Saving Time. The time is displayed in the 24 hour format. Here are a couple of examples:
Daylight Saving Time starts in most parts of the United States on the second Sunday of
March. 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 Second, Sunday, March and 2:00.
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 Last, Sunday, March
and the last field depends on your time zone. In Germany for instance, you would select
2:00 because Germany's time zone is one hour ahead of GMT or UTC (GMT+1).
