An even simpler one is this.

Time is a concept invented by man to put a label on the duration between cause and effect. How far you can go and how long it takes to get there in a finite span.

Still, time itself as a "real phenomenon" doesn't make any sense no matter how you explain it.

What is time? GMT is 13:15

“Time is free, but it's priceless. You can't
own it, but you can use it. You can't keep
it, but you can spend it. Once you've lost it
you can never get it back.”

Here's one for you, you will but you won't, you do but you don't, what am I? Time. You will have time but you don't have time, you do have time but you don't have time.

Hic! One more for the road!  Hic!

The sun dial video paradox.

You are sitting in a space ship at Cape Canaveral
watching a video feed sent via wifi of a sun dial
next to the space ship.For all experiments on board
your ship you will use this video feed as a time keeper.
NASA will boost and aim the wifi signal so you can receive
it on your trip.Now you blast off into space and accelerate
to 99% of the speed of light.You now perform experiments
on your ship to test the speed of light in the ship
using the sun dial video feed as your clock to time
the experiments.If your experimentation doesn't yield
the correct speed for light you will know that
the speed of light is not a constant.

Time is a myth.

Nope and never has been. c is calculated in a vacuum where resistance is negligible. The denser the medium the more resistance it will find. The value last I heard was 3.00 X 10 (to the eighth) m/s in a vacuum. There are also measurements of time's propagation through air, water and other mediums. Differences are slight but differences nevertheless.

Goes well with parsley, sage, and rosemary.....

I know nothing of such things. But one thing bothers me about time.

People's use of the phrase, "end of time."

There is no such thing. Time is an infinite line that never ends. We are eternal beings. Time never ends. Things change, that's all.

When I expire so does time. jmho

The light dot paradox.

We have a simple light clock for our next experiment
and this is how it works.
A light flashes one quick pulse at a mirror and back
to a light detector.The distance the light travels takes
one billionth of a second at light speed.When the light hits
the detector it triggers the light to flash and advances our
clock read out one billionth of a second and continues until
we turn it off.The vertical size of the light dot that hits
the detector is one inch tall while we sit on earth.We now
place the clock in our space ship perpendicular to the ships
motion when flying.We leave earth and accelerate to a speed
close to the speed of light.Our clock slows down relative to
the observer on earth because from the earth view the clock light
now has to travel further to hit the detector in our clock
on the ship.We know that the further light travels the
more it spreads out.Now we in the ship are traveling
close to the speed of light,what is the vertical size of
the light dot on the detector?
