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?

Remains the same relative to distance traveled. At point 99c time dilation plays a huge role. Should you manage to match light speed that increase is exponential. 

Although the math may be correct the following is for your entertainment only.

In the Michelson Morley experiment the light traveled about 36 feet
a time of about 36 billionths of a second.
That means the earth traveled around the sun at 18.5 miles per second
and in 36 billionths of a second about .003 of a foot.
Draw a line 36 feet long now at the end draw a perpendicular line .003 of a foot,this is about 1/25 of an inch,
At the end of that line draw back to the beginning of the first line to make a triangle.
Now find the difference of the length of the two long lines.
That difference is the discrepancy you are looking for in the experiment .00000185185184788269066376558 of an inch.
Set up the experiment look in the eye piece then look away and move one of the mirrors .000002 of an inch
from the eye piece then look again and see if you notice.
Boost the earth to half the speed of light and see if you notice that in the eye piece.
After the above earth boost if you don't see it in the eye piece these are the possible reasons.
1. We aren't moving and live in a simulation.
2. The thing light travels through comes along in side your space ship and possibly
a good distance out side the space ship,in this case earth and we will arrive
at Andromeda soon.

Think of all the things around you. Those you can reach out and touch. Time though...its been here from the git go, is here now and will be here till the end. You just can't reach out and touch it. Time is also a constant. Its constantly moving forward. Don't believe me...look at your clock. It ain't running backwards.

But you can only experience time in the here and now. You can't experience the time before because you already did, no repeats allowed. You can't experience time after because it hasn't happened yet. So time does indeed move, forward, from one moment to the next. Time exists in the past, present and future but only the present can be experienced directly. One is behind you, the other in front with you in the middle. Time's arrow dude moves in only one direction regardless of how you perceive it. Fly in a plane from east to west. The time zones put you back in time but your watch says different. Einstein's frames of reference.

Yup but, like I said, you can only experience the now. You did the before and you have to wait for what comes next. I did my fair share of physics.
