Time is not a coordinate. But that doesn’t mean time isn’t real. For instance it seems inconvenient to formulate what an algorithm is in “timeless” semantics for physics. Scott Aaronson has a relevant essay about this here. Maybe to a lesser extent it seem inconvenient to talk about entropy.
Has anyone read “Time’s arrow and Archimedes’s point”?
That is one very good book. I had a two-part review on my old blog; Part one discusses the book’s position on the arrow of time in cosmology, and Part two its arguments concerning the arrow of time in quantum mechanics.
(Edited to correct mistake, both links were leading to the first part.)

These are really excellent reviews.
Thank you!
