If daylight saving time is in force on the selected date, check the daylight saving time box; otherwise, make sure that it is unchecked.

The date and time indicates whether the time zone is in daylight saving time or standard time.
The verdict on energy savings isn't unanimous. Other studies do suggest that energy gains can be had under daylight saving time—at least in some places.
Regional variations due to differences in climate might also mean permanent daylight saving time could conserve energy in some areas but not as much in others.
