Local time of day in a location would be easier (and the model more complete) with rendering a dark ellipse, much like the moons shadow, to represent the unlit side of Earth at all points in time during an eclipse event. Since only half the Earth is ever shaded figuring out the size of the ellipse will be trivial but figuring out positioning throughout the day could take some number crunching.
