This is like claiming that there is no physical temperature because "hot" water for a bathtub is different from "hot" water for a tea (and different from "hot" air during a summer day).
Perhaps we should use two different word for the "perceived time" and for the "clock time". The good days, when I go to sleep all the night appears to go away in an instant, but it isn't. It's more useful to have a physical defined "clock time" and then explain why the brain is bad estimating durations using the "perceived time".
Yeah, I think his point is just to argue against scientific supremacy. Using different terms for the scientific and perceptual aspects of time would be one way of meeting his goal.
