zone and Greenwich Mean Time (GMT). 
Manual Daylight 
Saving 
Daylight saving is a period from late spring to 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 to manually enter Daylight Saving Time settings. Clear this option to 
have the NSA automatically retrieve Daylight Saving Time settings from the Internet. The 
NSA will download a new daylight saving resource file from the Internet every month.
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

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.

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 OctoberLast
Sunday. The time you specify depends on your time zone. In Germany for instance, you
