ZyXEL NWA-1100 User’s Guide

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

When you turn on the ZyXEL Device 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 ZyXEL Device 
then attempts to synchronize with one of the following pre-defined list of NTP time servers.

The ZyXEL Device 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. 

Start Date 

Configure the day and time when Daylight Saving Time starts if you selected 

Enable Daylight Saving. The at field uses the 24 hour format. Here are a 

couple of examples:
Daylight Saving Time starts in most parts of the United States on the second 

Sunday of March. Each time zone in the United States starts using Daylight 

Saving Time at 2 A.M. local time. So in the United States you would select 

Second, Sunday, March and 2:00.
Daylight Saving Time starts in the European Union on the last Sunday of 

March. All of the time zones in the European Union start using Daylight Saving 

Time at the same moment (1 A.M. GMT or UTC). So in the European Union 

you would select Last, Sunday, March. 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).

End Date 

Configure the day and time when Daylight Saving Time ends if you selected 

Enable Daylight Saving. The o'clock 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 2:00.
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).
