29.4.1 Pre-defined NTP Time Servers List
When you turn on the NXC for the first time, the date and time start at 2003-01-01 00:00:00. The NXC then
attempts to synchronize with one of the following pre-defined list of Network Time Protocol (NTP) time
servers.
The NXC continues to use the following pre-defined list of NTP time servers if you do not specify a time
server or it cannot synchronize with the time server you specified.
When the NXC uses the pre-defined list of NTP time servers, it randomly selects one server and tries to
synchronize with it. If the synchronization fails, then the NXC goes through the rest of the list in order from
the first one tried until either it is successful or all the pre-defined NTP time servers have been tried.
29.4.2 Time Server Synchronization
Click the Synchronize Now button to get the time and date from the time server you specified in the
Time Server Address field.
When the Loading message appears, you may have to wait up to one minute.

The Current Time and Current Date fields will display the appropriate settings if the synchronization is
successful.
If the synchronization was not successful, a log displays in the View Log screen. Try re-configuring the
Date/Time screen.

1 Click System > Date/Time.
2 Select Manual under Time and Date Setup.
3 Enter the NXC’s time in the New Time field.
4 Enter the NXC’s date in the New Date field.
