Section 3 - Configuration
Daylight Saving time ends in most parts of the United States on the
first Sunday of November. Each time zone in the United States must
use Daylight Saving time at 2:00 A.M. Thus, in the United States you
must set November, First, Sunday, at 2:00 A.M as your end time.
Daylight Saving time ends in the European Union on the last Sunday
of October. For instance, in Germany you must type 2 because
Germany's time zone is 1 hour ahead of GMT (GMT+1). Thus, in
Germany you must use March, Last, Sunday, at 1:00 A.M.
SET THE DATE AND TIME MANAULLY
You can also use Copy Your Computer's Time Settings to
synchronize the Date and Time to your local PC. Or, you can also
adjust Year/Month/Day/Hour/Minute/Second manually.
