between your time zone and Greenwich Mean Time (GMT).
Daylight Savings
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
Daylight Savings

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).
