Auto Time Changing Skins -- Can it be done??

[dbsguy]

I been digging with no luck across the internet looking for a way to change a forum's skin from day time to night time by looking at the local members computer time.
Place in the admin panel to where you could turn it off or on & then pick your default day skin & night skin, after that the admin can then set the times it would change from day to night & back.

Has this been done or can be it even be done??

Thanks for the comments
