What IS time?

[pjs]

Time is that property of the universe that gives us an excuse to buy a watch. A really nice Rolex if we have the $$$.

It seems that time is relative.

Maybe even relative in the same way as if you throw a baseball towards the centre of big bang impact, you will decrease it's net kinetic energy by the same amount that you would be adding to it, had you thrown it in the opposite direction.

Or something...

Nor is time a constant. Time is relative to motion. They have performed experiments with highly accurate clocks, where one remained on the earth, while the other orbited in a supersonic plane, and there was a time difference between the two. It is theorized that as you approach the speed of light, time slows down more and more.

What is really interesting, is wondering how time would change if the Earth was to stop revolving at the precise speed that is does now.
