As a convenience to our customers, we have always embedded the dates for the start and end of Daylight Savings Time into our products that have clocks. Below is a chart to indicate the start and end of Daylight Savings for the next few years.




Prior to 2008, the start date for DST was the first Sunday in April, and the end of DST was the last Sunday in October.
This change was put into effect through an act of Congress and will have an impact on all products that contain real time clocks.
Below are links to information on various Watt Stopper products that have such real time clocks and how to handle daylight savings time adjustments properly.
