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
. The
at
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 select
Second
,
Sunday
,
March
and
select
2
in the
at
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
at
field depends on your time zone. In
Germany for instance, you would select 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
at
field uses the 24 hour format. Here are a couple of examples:

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
First
,
Sunday
,
November
and select 2 in the
at
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
