15.3.1 Pre-defined NTP Time Servers List
When you turn on the NWA3000-N series AP for the first time, the date and time
start at 2003-01-01 00:00:00. The NWA3000-N series AP then attempts to
synchronize with one of the following pre-defined list of Network Time Protocol
(NTP) time servers.
The NWA3000-N series AP 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 NWA3000-N series AP 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 NWA3000-N series AP 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.
End Date
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).
Offset
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.
