Manual

Select this radio button to enter the time and date manually. If you configure a

 

 

new time and date, time zone and daylight saving at the same time, the time

 

 

zone and daylight saving will affect the new time and date you entered. When

 

 

you enter the time settings manually, the ZyWALL uses the new setting once you

 

 

click Apply.

This field displays the last updated time from the time server or the last time

and then click Apply.

 

 

 

 

New Date

This field displays the last updated date from the time server or the last date

 

(yyyy-mm-dd)

configured manually.

 

 

When you set Time and Date Setup to Manual, enter the new date in this field

 

 

and then click Apply.

 

Get from Time

Select this radio button to have the ZyWALL get the time and date from the time

 

Server

server you specify below. The ZyWALL requests time and date settings from the

 

 

time server under the following circumstances.

 

 

• When the ZyWALL starts up.

 

 

• When you click Apply or Synchronize Now in this screen.

 

 

• 24-hour intervals after starting up.

 

 

 

 

Time Server

Enter the IP address or URL of your time server. Check with your ISP/network

 

Address

administrator if you are unsure of this information.

 

 

 

 

Synchronize Now

Click this button to have the ZyWALL get the time and date from a time server

 

 

(see the Time Server Address field). This also saves your changes (except the

 

 

daylight saving settings).

 

 

 

 

Time Zone Setup

 

 

 

 

 

Time Zone

Choose the time zone of your location. This will set the time difference between

 

 

your time zone and Greenwich Mean Time (GMT).

 

 

 

 

Enable Daylight

Daylight saving is a period from late spring to early fall when many countries set

 

Saving

their clocks ahead of normal local time by one hour to give more daytime light in

 

 

the evening.

 

 

Select this option if you use Daylight Saving Time.

 

 

 

 

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 type 2 in the at field.

 

 

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).
