Sunset, sunrise, twilight calculations in LC?

Hi List People,
Does anyone know of an LC version of sunrise/sunset and twilight calculations?
I found a couple of web based APIs, but I'd like it to work offline.
I found this: http://en.wikipedia.org/wiki/Sunrise_equation ... but it's going to take me a while to translate that into LC, which is why I'm asking.
