DESCRIPTION
This field displays the present time of your NXC.
This field displays the present date of your NXC.
Select this radio button to enter the time and date manually. If you configure a new time
and date, time zone and daylight saving at the same time, the time zone and daylight
saving will affect the new time and date you entered. When you enter the time settings
manually, the NXC uses the new setting once you click Apply.
This field displays the last updated time from the time server or the last time configured
manually.
When you set Time and Date Setup to Manual, enter the new time in this field and
then click Apply.
This field displays the last updated date from the time server or the last date configured
manually.
When you set Time and Date Setup to Manual, enter the new date in this field and
then click Apply.
Select this radio button to have the NXC get the time and date from the time server you
specify below. The NXC requests time and date settings from the time server under the
following circumstances.
• When the NXC starts up.
• When you click Apply or Synchronize Now in this screen.
• 24-hour intervals after starting up.
Enter the IP address or URL of your time server. Check with your ISP/network
administrator if you are unsure of this information.
Click this button to have the NXC get the time and date from a time server (see the
Time Server Address field). This also saves your changes (except the daylight saving
settings).
Choose the time zone of your location. This will set the time difference between your
time zone and Greenwich Mean Time (GMT).
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 Enable
Daylight Saving. The at 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 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 type
2 in the at 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 Last,
Sunday, March. The time you type in the at field depends on your time zone. In
Germany for instance, you would type 2 because Germany's time zone is one hour
ahead of GMT or UTC (GMT+1).
