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 (mm/
dd)
Configure the day and time when Daylight Saving Time starts if you selected
Daylight
Savings

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 select 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 select in the
o'clock

instance, you would select 2 because Germany's time zone is one hour ahead of GMT or
UTC (GMT+1).

United States you would select
Last
,
Sunday
,

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
