Don't know if anyone's ever come across something like this, but I need a way to display a bit of HTML with info of who is on air at certain times of day (ie. every hour). I currently manage this with Javascript (see www.offthechartradio.co.uk), but for the new site i'm designing for several reasons this won't work.

Ideally i'd like the index.php file to work out the current time and then call up the correct bit of code for that time from another file.

Hopefully someone's come across one of these in the past, any help much appreciated but bear in mind i'm a complete PHP novice
