Daylight Saving Time (DST) is the practice of temporary advancing clocks during the
summer time so that evenings have more daylight and mornings have less. Typically,
clocks are adjusted forward one hour at the start of spring and backward in autumn.
Many countries have used the DST at various times, details vary by location. By default,
the DST is set to Automatic, so it can be adjusted automatically from the current time
