Program your city’s latitude and longitude into the Aube Solar Timer Switch and the thing will automatically turn your lights on and off according to sunset and sunrise. It doesn’t however adjust for daylight savings, so it ain’t that clever. Pah! $39.99.
You don’t have to spend hours adjusting the programmed on and off times on a light switch timer as the seasons change. Program your lights to turn on at sunset based specifically on your area with the Aube Solar Timer Switch, 40-500W, an attractive Decora-style timer switch that can control incandescent, halogen or fluorescent lighting.
I can't believe you think the sun knows about the human concept of daylight saving. The sunrise and sunset is not related to our clocks, whch is the purpose of the solar clock.
