Start Date

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

Daylight Savings. The o'clock 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 first 

Sunday of April. 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 First, 

Sunday, April and type 2 in the o'clock 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 o'clock 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 

Daylight Savings. 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 last Sunday of October. 

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 Last, Sunday, October and 

type 2 in the o'clock 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 o'clock 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).
