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.
Table 57 Default Time Servers
0.pool.ntp.org
1.pool.ntp.org
2.pool.ntp.org
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.

DESCRIPTION
Configure the day and time when Daylight Saving Time ends if you selected Enable
Daylight Saving. The at field uses the 24 hour format. Here are a couple of examples:
Daylight Saving Time ends in the United States on the first Sunday of November. Each
time zone in the United States stops using Daylight Saving Time at 2 A.M. local time. So
in the United States you would select First, Sunday, November and type 2 in the at
field.
Daylight Saving Time ends in the European Union on the last Sunday of October. All of
the time zones in the European Union stop using Daylight Saving Time at the same
moment (1 A.M. GMT or UTC). So in the European Union you would select Last,
Sunday, October. The time you type in the at field depends on your time zone. In
Germany for instance, you would type 2 because Germany's time zone is one hour
ahead of GMT or UTC (GMT+1).
Specify how much the clock changes when daylight saving begins and ends.
Enter a number from 1 to 5.5 (by 0.5 increments).
For example, if you set this field to 3.5, a log occurred at 6 P.M. in local official time will
appear as if it had occurred at 10:30 P.M.
Click Apply to save your changes back to the NWA.
