I am lookin for a script that will post a specified text link or image on a schedule based upon the clock on the computer the host resides...

so that for like conferences, if you went to look at the page it would say which conference is in process right now and which one was next... based off a xml list or even a .csv sheet or whatever...

I am pretty sure I have seen stuff like that before but I can't remember where, maybe on a radio stations page so that it tells you which DJ is up and which is next...

anyone know of anything like that and where I might be able to find it?

Thanks,
Kelwin
