Daylight Saving Time
The Daylight Saving Time is a widely used system of adjusting the official local time forward to save
energy. The uniform time adopted during the implementation of this system is known as the DST.
Typically, clocks are adjusted one hour forward in the summer to make people early to bed and
early to rise so as to make full use of illumination resources and save electricity. Clocks are adjusted
backward in autumn. The specific DST regulations vary with countries.
To meet the DST requirement, the device supports the DST function to adjust forward one hour at
×× (Hour): ×× (Minute) ×× (Day) ×× (Month) and backward one hour at ×× (Hour): ×× (Minute) ××
(Day) ×× (Month).
