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).
