Fun book about this here
Julian Barbour's The End of Time and Lee Smolin's Time Reborn are foils to each other that examine this question from more of a scientific/physics point of view. I've at least read Barbour's book and it deals thoroughly with the scientific advancements that Einstein and Mach have made.
It's not that crazy of an argument. https://www.amazon.com/End-Time-Next-Revolution-Physics/dp/0195145925 by Justin Barbour is a physics explanation where he believes the universe evolves minute to minute, and with the result that the 'laws' and 'constants' change over time, which dove tails with the mention of those constants in the video.
This is an interesting book with a different perspective
> Richard Feynman once quipped that "Time is what happens when nothing else does." But Julian Barbour disagrees: if nothing happened, if nothing changed, then time would stop. For time is nothing but change. It is change that we perceive occurring all around us, not time. Put simply, time does not exist.
