Time Server Address
Select a time server from the drop-down list box or select Specify my 
own time server
 and enter the time server you wish to use in the field 
below. Check with your ISP/network administrator if you are unsure of this 
information.
Time Zone 
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 
Saving 
Daylight saving is a period from late spring to early fall when many 
countries set 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 hour 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 use March, SecondSunday, at 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 March, LastSunday. The time you 
specify 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 
NovemberFirstSunday, at 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 OctoberLastSunday. The time you 
specify 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 by how many hours to change the time for Daylight Saving Time.
