Abstract: A method and device that controls one or more apparatus in relation to the expected time of sunrise and sunset at the location of the apparatus. The operator enters a geographic location identifier, such as a zip code or telephone area code, and the controller computes the expected time of sunrise and sunset at the corresponding geographic location. The controller is configured to translate the entered geographic location code into the offset times, based upon the latitude and longitude of the location. The controller is able to either directly retrieve stored time offsets or it retrieves the latitude and longitude that corresponds to the entered geographic location code and determines the time offset from that latitude and longitude.
