12.3.1 Pre-defined NTP Time Servers List
When you turn on the NWA for the first time, the date and time start at 2003-01-01 00:00:00. The
NWA then attempts to synchronize with one of the following pre-defined list of Network Time
Protocol (NTP) time servers.
The NWA 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 NWA 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 NWA 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.
12.3.2 Time Server Synchronization
Click the Sync. 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.
