Use Time
Server when
Bootup 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.
Time Server IP
Address 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.
Current Time This field displays the time you open this menu (or refresh the menu).
New Time
(hh:min:ss) Enter the new time in hour, minute and second format. The new time
then appears in the Current Time field after you click Apply.
Current Date This field displays the date you open this menu.
New Date
(yyyy-mm-dd) Enter the new date in year, month and day format. The new date then
appears in the Current Date field after you click Apply.
Time Zone 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 Time 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.
Start Date 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).
