Lighting delays?

[twistedtails]

I was wondering if any of you guys would know how to set up the lights in my ball room to turn off when the sun goes down? I think I have to use some kind of delay right? I'm not sure though. Your help would be breatly appreciated. Thanks.

Personally i would just either get a timer and set it for 12 hrs light and 12 hrs darkness. What happens if its dark outside during the day?No lights for Mr Binky?Just kidding but anyway i think they make timers for light switches or even just the ones for the outlets but in this situation simple is better and alot more reliable.
