14.3.1 Pre-defined NTP Time Servers List
When you turn on the NWA/WAC for the first time, the date and time start at 2003-01-01 00:00:00. The
NWA/WAC then attempts to synchronize with one of the following pre-defined list of Network Time
Protocol (NTP) time servers.
The NWA/WAC 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.
Table 67 Default Time Servers
0.pool.ntp.org
1.pool.ntp.org
2.pool.ntp.org
When the NWA/WAC 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/WAC 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.
