DESCRIPTION
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.
Configure the day and time when Daylight Saving Time starts if you selected
Daylight Savings. The 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).
Configure the day and time when Daylight Saving Time ends if you selected
Daylight Savings. The o'clock 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 Last, Sunday, October and
type 2 in the 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 (1 A.M. GMT or UTC). So in the European Union you
would select Last, Sunday, October. 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).
