characters in length) of your time server.

Check with your ISP/network administrator if you are unsure of this information.

Time Zone

Time zone offset

Choose the time zone of your location. This will set the time difference between your time 
zone and Greenwich Mean Time (GMT). 

Daylight Saving

Daylight Saving Time 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.

State

Select Enable if you use Daylight Saving Time.

Start rule:

Configure the day and time when Daylight Saving Time starts if you enabled Daylight 
Saving. You can select a specific date in a particular month or a specific day of a specific 
week in a particular month. The Time 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, set the day to Second, Sunday, the month to March 
and the time to 2 in the Hour 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 set the day to Last, Sunday 
and the month to March. The time you select in the o'clock field depends on your time 
zone. In Germany for instance, you would select 2 in the Hour field because Germany's 
time zone is one hour ahead of GMT or UTC (GMT+1). 

End rule

Configure the day and time when Daylight Saving Time ends if you enabled Daylight 
Saving. You can select a specific date in a particular month or a specific day of a specific 
week in a particular month. The Time 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 set the day to First, Sunday, the month to November 
and the time to 2 in the Hour 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 set the day to Last, Sunday, 
and the month to October. The time you select in the o'clock field depends on your time 
zone. In Germany for instance, you would select 2 in the Hour field because Germany's 
time zone is one hour ahead of GMT or UTC (GMT+1).
