Daylight Saving Daylight Saving Time 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.
State Select Enable if you use Daylight Saving Time.
Start rule: Configure the day and time when Daylight Saving Time starts if you enabled Daylight
Saving. You can select a specific date in a particular month or a specific day of a specific
week in a particular month. The Time 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, set the day to Second, Sunday, the month to
March and the time to 2 in the Hour 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 set the day to Last,
Sunday and the month to March. The time you select in the o'clock field depends on
your time zone. In Germany for instance, you would select 2 in the Hour field because
Germany's time zone is one hour ahead of GMT or UTC (GMT+1).
End rule Configure the day and time when Daylight Saving Time ends if you enabled Daylight
Saving. You can select a specific date in a particular month or a specific day of a specific
week in a particular month. The Time field uses the 24 hour format. Here are a couple
of 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 set the day to First, Sunday, the month to November
and the time to 2 in the Hour 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 set the day to Last,
Sunday, and the month to October. The time you select in the o'clock field depends
on your time zone. In Germany for instance, you would select 2 in the Hour field
because Germany's time zone is one hour ahead of GMT or UTC (GMT+1).
