Track real life time spent in different dimensions

In the pause menu, there is a way for each player to see their statistics in that current world. There are a few statistics that show real life time. Sneak Time, Time Played, Time Since Last Death, and Time Since Last Rest.

My suggestion is to track the real time the player has spent in the Overworld, The Nether, and The End. We are already able to see how much time we've spent in one world, why not be able to see how long we've spent in each dimension? 

This doesn't add anything groundbreaking or game changing. I just think it would be nice for the people that work on big projects in The Nether and The End to see how long they've spent there.
