Sounds like a deep quote I read from that page in Reader's Digest.

If that page was authored by Douglas Adams then yes that’s where you read it.

I was making a reference the next line in the book:

"Very deep," said Arthur, "you should send that in to the Reader's Digest. They've got a page for people like you."

I think the answer to this is to do more interesting things on a regular basis. If every weekend you do something different, then the month feels longer than when you stay home every weekend.

I've long been skeptical of this explanation. Later school ages (junior high and high school) were probably the most monotonous and regimented part of my life, period—I've certainly never experienced that much concentrated, intense boredom without any way to do anything about it—yet subjective time had only barely sped up from elementary school. It should then have slowed way down in college, but it didn't. It should…

I've had a pretty opposite experience. The busier I am, the more I have to process, and time feels to pass more slowly. I feel like the first 6 months of my kids life took at least twice that.

The speed of light is still just the movement of something over a measured distance.

I can flip that around and say that a distance is just the movement of something over a measured time. By your original argument, distance doesn't exist.

Given distance, velocity and time; choose any two as physical and the third will be emergent. Choose according to the view you want to explore.

(How embarrassing.)

Time is the direction in which entropy always increases. It's the most real thing there is.

does entropy always increase? are there systems or forms of matter that literally cheat entropy?

Any system can cheat entropy as long as it's not a closed system, by decreasing locally but increasing it globally. Life is a good example.

Time doesn't exist as an independent physical objective entity , it exists only as a measurement. Sometimes we represent that measurement with physical objects, such as with clocks or watches or in our heads (I can hold my breath for N seconds). It's no different than your height existing as a measurement, or the distance from here to the wall existing a measurement, or the distance of 10 meters existing. There are p…

That's certainly one view of time. Relativity views all time as existing "simultaneously"; the block universe. The past exists along with the future. The passage of time is then just an illusion seen from within the greater whole.

I prefer a view of time closer to yours I think, where there is a single moment of existence, the now, that evolves.

Or at least tends to increase. Entropy can always spontaneously decrease, or can simply not increase for a moment. This was actually discussed a week ago! [1] As discussed in those comments, entropy isn't well-formulated outside of equilibrium states, and is subjective: it is a function of an observer's knowledge of the system (particularly microstates). I'd say time is very real, and an inescapable part of experienc…

velocity is defined as distance over unit time so I’m not sure how you square that circle

Semantics but velocity being a measurement of somethings movement through a distance is exactly what I'm saying time is. I've stated that we use time to describe stuff, like velocity. But "time" as a physical property like gravity does not exist.

You could probably replace the usage of "time" with "increase in entropy", but it just makes it harder to understand WRT velocity. As your velocity increases, the entropy in the universe has increased as a result of whatever mechanism for acceleration is being used. If it's gas, then you are going from a nice, mostly orderly/low entropy liquid in a container, to a chaotic, high entropy gas that's now in the atmosphere.
