Adding, Subtracting, Comparing Times

[Christopher Robin]

Oh, hehehe, my goodness no, nothing like that kind of complicated! This is just to time some simple graphic changes: for instance, a sun thatgoes up and down. Just up and down, not even in a circle -- the minutes from SunsetBegin to SunsetEnd literally set the picture's Y index. It's kind or tricky keeping track of which values are supposed to go up, which ones down, and by how much, but all the real sophistication in this particular project is over in Photoshop. No serious weather-skin maker would believe their eyes if they saw how few are the indexes in my WebParser capture.
