node.js - NodeJs - update the response after a countdown

Question

I want to show a countdown. And when that countdown reaches 0 to enable an iframe with content from another site (without the user refreshing).

But I don't want the link to the iframe to be accesible to clients before the time is up. So i thought of using nodejs to dynamically update the content after a timer.

I'm very noob in nodejs (i know how to set up express and deliver some static pages). Could you point me in the right direction? How do I update content dynamically and how do I call a function at a certain date? Thanks!
