3.4.1 Pre-Defined NTP Time Servers List
The WiMAX Modem uses a 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.
It can use this list regardless of the time protocol you select.
When the WiMAX Modem uses the list, it randomly selects one server and tries to
synchronize with it. If the synchronization fails, then it goes through the rest of
the list in order until either it is successful or all the pre-defined NTP time servers
have been tried.
