Start Date (mm-

nth-week-hr)

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

in the Daylight Saving field. The hr 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 Apr., 1st, Sun. and type 

02 in the hr 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  

Mar., Last, Sun. The time you type in the hr field depends on your time zone. In 

Germany for instance, you would type 02 because Germany's time zone is one 

hour ahead of GMT or UTC (GMT+1). 

End Date (mm-

nth-week-hr)

Configure the day and time when Daylight Saving Time ends if you selected Yes in 

the Daylight Saving field. The hr 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 Oct., Last, Sun. and type 02 in 

the hr 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 

Oct., Last, Sun. The time you type in the hr field depends on your time zone. In 

Germany for instance, you would type 02 because Germany's time zone is one 

hour ahead of GMT or UTC (GMT+1).
