Daylight Savings 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.
Active Click this switch to enable or disable Daylight Saving Time. When the switch goes to the right
, the function is enabled. Otherwise, it is not.
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
Hour 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

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

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).
