Summer Time Hours, also referred to as Daylight Savings Time (DST), is
the strategy of moving clocks ahead to provide greater amounts of daylight
in the afternoon and to standardize time with other parts of the world. In
many parts of the world, the Summer Time Hours algorithm is based on a
standardized rule. For example, in the Western hemisphere, the rule used by
most locations in Canada, Mexico, and the United States is to set clocks
forward by one hour at 2:00 a.m. on the first Sunday in April and back an
hour at 2:00 a.m. on the first Sunday in October annually. Many countries in
Europe and Asia follow similar rules. The offset, or amount of time by
which the clock is set forward or backward, varies from country to country.
Many parts of the world follow a one-time change of Summer Time Hours.
When you configure the switch for these locations, you reset the clock by
specifying a scheduled time and date.
