Sunset algorithm for Propeller

MJHanagan

Does anyone have a relatively simple algorithm to calculate sunset time based on the date, lattitude and longitude? Something using all integer math would be ideal returning the number of minutes passed noon or midnight would be all I would need.

Wikipedia has some good formulas for sunset, sunrise and noon.
