This section provides some technical information about the topics covered in this chapter.

5.6.1 Pre-defined NTP Time Servers List

When you turn on the NWA for the first time, the date and time start at 2000-01-01 00:00:00.
When you select Auto in the System > Time Setting screen, the NWA then attempts to
synchronize with one of the following pre-defined list of 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.
Table 10 Default Time Servers
ntp1.cs.wisc.edu
ntp1.gbg.netnod.se
ntp2.cs.wisc.edu
tock.usno.navy.mil
ntp3.cs.wisc.edu
ntp.cs.strath.ac.uk
ntp1.sp.se
time1.stupi.se
tick.stdtime.gov.tw
tock.stdtime.gov.tw
time.stdtime.gov.tw
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.
