Time exist but its mostly used to clock productivity.

That is where I see problems with time.

How long youth last?

How long summer last?

How long I have to work?

What time I have to get up?

What time I have to sleep?

Do I have time to take a quick nap?

Can I beat this former record in time - like eating more hot dogs?

Time is being used for very wacky things in our societies.

Also how we measure it in seconds minutes hours days months years might have to change.

We are trying to measure in it atomically.

Atoms have half life or something of that effect.
