33.3.1 Pre-defined NTP Time Servers List

When you turn on the NXC for the first time, the date and time start at 2003-01-
01 00:00:00. The NXC then attempts to synchronize with one of the following pre-
defined list of Network Time Protocol (NTP) time servers.
The NXC 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 177 Default Time Servers
0.pool.ntp.org
1.pool.ntp.org
2.pool.ntp.org
When the NXC 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
NXC 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.
