Daytime to Night time?

i remember seeing this on a zombie dm server a long time ago and i thought, this would be more helpful for a rp server. basicly every minute or so it got darker and dark until it was really dark then it was light again. now it was ridiculously fast but i was thinking you could tweak it so its rate was a lot slower so its more realistic. i think it'd be a good idea because people would be encouraged to do some planning, should we do this at night? too many people witnessing. and i heard you guys got vampire rp mod so this kind of came up in my mind. maybe vampires only feed during night? just a suggestion tell me what you guys think

at this point in time there is no good day/night mod for ARP.

I had one on the server while hosting Mevelport, but it crashes the server too much.
