Going through the description of time given by Newton, I found that Newton had formulated the definition in a very complex language. Can anyone simplify it?

Time is quantified motion.
It's the thing we use to measure motion and changes, but we also use motion to measure time. There is no mechanism we have for measuring time that doesn't use motion (sun dial: motion of earth relative to the sun, mechanical watches: motion of gears and springs, atomic clocks: oscillating motion of a cesium atom).
Bottom line: we measure motion against other, precisely defined and calibrated motion. We call those measurements TIME.

Newton Was superceded by Einstein so it is needed to go to Einstein Relativity theory where Time calculation and description is more exact. It is based on a frame of reference which newton considered absolute. Einstein implied that there is no absolute frame of Reference.His time formula is based on a Universal velocity of light. T^2 =To ^2 * [ C^2/(C^2-V^2) ].
note if You divide Einstein's spacetime by space the result is time.

It's very difficult to explain time without using a synonym of time. Some people say time is duration, duration means the same thing as time, so that's not a good definition.
If I were to try to come up with a definition, I would say time means a series of any event passing through a fixed reference.

Simply, early man needed a way to put life in perspective in order to survive. At first lunar cycles were used to help with agriculture, i.e. the 'time' to plant and harvest their crops. Also how else could they, and we, today plan for any event such as a raid on a neighbooring clan or a date at the local coffee shop without having a solar cycle as well, yesterday/today/tomorrow. Less simply time to us is a measure of how rapidly change occurs in an environment.

Physical time is a velocity - "c". This is the common value to all mass and energy. Physical time is demonstrated to us in the passage of events, all moving past, present, and future at the same rate everywhere. Were there any event not moving at this rate, then it would have no existence to us.

Even thought the measurement of time is a human fabrication, The concept of time is real, since things do get older.
I would say that time is a limitation of the universe, since we it only flows in one direction (so far it wasn't proven otherwise), and it's measurement is necessary for the estimation of duration of everything.

A second is defined as 9,192,631,770 cycles of radiation from a Caesium 133 radio-isotope.
You know the rest...

Time is defined with a dependancy of which side of the bathroom door you are on and how bad you have to go.

Fenman always said, "If we cannot explain something in simplest of languages then it means we haven't fully understood the thing."
I think TIME is the best example of that.
BTW, my best shot at the definition of time would be "for any thing to move in the universe it requires time".......or........"without time nothing can move" [including electrons, protons, planets, stars....anything that you can think of]

time is a very complex thing.
time is the past, present and future.
