3.7.6. Setting the Daylight Saving Time Rules
Daylight Saving Time (DST) or Summer Time as it is called in many countries, is a way of getting more
daylight out of the summer days by advancing the clocks by one hour during the summer. Then, the
sun will appear to rise one hour later in the morning when people are usually asleep anyway, at the
benefit of one hour longer evenings when awake. The sunset and sunrise are one hour later than
during normal time.
