how to sync time with agenda?

Hello all of you out there!

I'm busy working on a schoolproject with a classmate of mine. What we're trying to do here is creating a digital agenda that's up to date.

Sort of like Google Agenda, where time is synched with how the agenda is viewed. For example it's 9 o'clock and so does the agenda shows.

I can't seem to think how this can work. It only has to be a prototype, but it still has to show how it works and that it is able to work.

So does anyone know how to do that or which components do I have to use? Is it perhaps better to work with movieclips or anything?

Help !! Thanks so much
