That story about how he saw that huge clock in england but really the clock clicked to twelve a couple seconds before he saw it meaning that the light had to travel from the clock and make a reflection which caught his eye. So he thought about velocity = distance over time and concluded that time stops in velocity for very little seconds...something like that, explain the story and the point!

The clock measured time. The time that it measures is not exact relative to the Gravitational time as follows;
The rotation of the gear in the clock slows down due to friction causing a time delay .
Therefore, when reading the time we cannot measure momentum and position exactly. as soon as we measure one the other has changed.
Hence the further away you are from the clock the more time dilation you read.
The delay in reading the clock is due to the extra time that the light flux on the face of the clock is sending you information at a certain velocity to your eyes and after that additional delay , the brain finally logs in the time.
However the time read is dilated as a function of the information velocity of the transmission.
Therfore , on that basis Einstein developed the Concept of dilated time when interpreting the time reading on a clock.
Neverthe less the velocity of the light signal change according to the medium's index of refraction ,which in this case is the eye.
So the reading of time on a clock is more complicated then meets the eye;
It is very much related to the distance you read the clock from.

distance = rate x time

Maybe if everyone is standing their looking at the clock they all get the perception of exactly what time it is. It's a perception because it takes time for the light from the clock to reach your eyes and be processed by your brain. Most of the time you are not aware of that.

Also you can take a small amount of matter and create a tremendous amount of energy.

speed of light through space 186,282 miles per second

so if a star is 200 light years away pack a lunch if you go to visit it.
