B What qualities does time have other than linearity, motion, and speed?

[atlanticus]

TL;DR Summary

It can be something simple.

For example, things are caused by things, things move or don't move, there are big movements and small movements.

It's tied to the speed of light - so, in that sense, it "has speed".
It has an apparent cause-effect directionality.
You can use a clock to measure it. And in this classical Physics forum, two accurate clocks will agree with the amount of time that has elapsed.

Why do you ask?

Thank you, I saw online a riddle that said time has seven components. I'm trying to figure out the last part. Is there something that time isn't hindered or affected by or vice versa?

Our passage through time goes unhindered. Unless you're Phil the weatherman, you can't stop and redo today over and over.

I would guess that if anyone has a notion of "seven components" of time, they are very human-centric components and are unrelated to the way Physics treats time.

Time is an illusion. Lunchtime doubly so.

TL;DR Summary: It can be something simple.

There's no sensible answer to your question until you have defined what you mean by the word "time".
This being a physics forum where we discuss measurable quantities and the math that describes their behavior, it might be best to go with Einstein's definition: "Time is what a clock measures".

This definition is easiest to appreciate when we compare it with the analogous definition of distance: "distance is what a ruler measures" and is far more profound than it appears at first glance. And once you understand it you will be able your question for yourself.

Huh? What do you mean by "motion" of time? Time always moves forward (locally) at one second per second. I guess you could call that either motion or speed or both. Did you mean something else? It is linear in that time is always towards the future although I have a hard time calling that "linear".
