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.

 

 

 

 

Sync. 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 their

 

Saving

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).

 

 

 

 

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.

 

 

 

 

Apply

Click Apply to save your changes back to the ZyWALL.

 

 

 

 

Reset

Click Reset to return the screen to its last-saved settings.
