Quote from Leon in Dick's First Birthday
Dick: The truth is, time measured in years would have no significance at all if a second-rate sun hadn't pulled this planet into the little suck party we call gravity, causing everything on it to wither and die. Thoughts on that? Bug? Bug: It doesn't look dyed to me. Dick: Let me simplify. If a year is not a year anywhere but Earth, what does that make time in the universe? Leon, time is what? Don't think, Leon. Just answer. Time is what? Take a shot. Go! Leon: Time is relative? Dick: My god, Leon, you're right! Leon: My head hurts.
