Virtual Conference - Timed session media

I've been asked to build a virtual conference site on Squarespace. 

A sample site my client had seen (also on Squarespace) showed a way to show the conference media on a time-released scheduler. That is, there was a schedule displayed, but the "next session" video was not available until the specific time it was supposed to be. It looked like a playlist, but acted more like an event schedule that released media content at approved times. 

I've never built a Squarespace site, so I'd be learning the platform - as well as unique functionality like this.

Can you tell me if/how this kind of thing would be accomplished here on the platform?

(And - any other tips, suggestions, themes, etc. to begin building a Virtual Conference.)
