Time spent on various sections using Google Analytics

I'm fairly new to Google analytics. I am looking at a single page website , with say about multiple "screens" or sections from top to bottom. When you scroll down you go to the next screen.

What I need is a way to use Google Analytics , to find out how much time a user spends on each screen , is there a way to do this ?? Please note that its not a mobile app, but a website.

I found a plugin called "ScreenTime" but it had some limitations wrt GA integration.

Can someone help please!

Thanks
