Manual Daylight
Saving
Daylight saving is a period from late spring to 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 to manually enter Daylight Saving Time settings.
Start Date Configure the day and time when Daylight Saving Time starts if you selected Enable Daylight
Saving. 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 you would use March, Second, Sunday, at 2:00.
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 March, Last, Sunday. The time you
specify 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).
End Date Configure the day and time when Daylight Saving Time ends if you selected Enable Daylight
Saving. 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 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 select November, First, Sunday, at 2:00.
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 October, Last, Sunday. The time
you specify 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).
Offset Specify by how many hours to change the time for Daylight Saving Time.
Apply Click this to save your changes. If you configured a new time and date, Time Zone and
Daylight Saving at the same time, all of the settings take affect.
Reset Click this to restore your previously saved settings.
