The Sylvania SA 300 is an industrial digital timer for lights and appliances. When you enter your area code into the timer, it adjusts year-round to sunset. It turns devices on at sunset and off after a specified amount of time. The digital timer also offers the option of turning off the automated zip-code-based timing and setting up to four manual times of your choice.
