Changing Background Help, background changes depending on time Options

[emojournal]

I'm definetely not a scripter, so if anyone knows of a script where I can get the background image to change depending on what time of day it is, that would be super awesome. I just want it so like:

5:01am - 9am: sunrise background
9:01am - 7pm: sunny picture
7:01pm - 9pm: sunset picture
9:01pm - 5am: night time picture

I'm wanting it to work with a skin as well. Don't know if it is possible, but it would be quite nifty. So thanks in advance for anyone who has an answer, or makes an answer.
