does time exist? only when you need it to. think, does time pass when you are dreaming? or asleep for that matter.anything else is pure speculation. for some interesting ideas on the time paradox read some of the early works of Clifford D Simak.

Well, aren't the concepts of clocks and grids completely man-made and arbitrary too?
I was serious when I challenged people to define the term "exist". Is there any point in arguing over the existence of objects that can't be observed? If an object can't ever be seen (or imagined?) by a conscious observer, or his instruments, can it be said to exist?
I think ultimately arguing over whether time and space "exist" is no different to arguing over whether a tree makes any noise if it falls over in the forest with nobody to hear it.
Some people take the uncertainty principle to mean that we actually create reality, that is cause it to exist, by observing it. All those little wave functions collapse when they are observed, or in more familiar terms, it's the act of opening the box that kills the cat.
By that argument, yes, the human concepts of time and space do exist because we thought of them. And the tree doesn't make any noise: air vibrations maybe, but no noise.
This reminds me of another one of those Zen stories: Two monks were watching a temple flag wave in the wind. "The flag moves", said one monk. "No, the air is moving and the flag only follows it" said the other. Just then a third monk passed by and said: "No, not the wind, not the flag: mind is moving"
And at that moment the two monks became enlightened, etc.

That is a very good point.
Existence has many different possible interpretations and possibly all of them are completely wrong, we know that at most one of them are right. The whole field is riddled with paradoxes, circular references and definitions of reality that incorporates consciousness.
Until all that has been figured out we can't fully explain time or even something basic as movement. The paradoxes that Zeno of Elea posed 2500 years ago turned out to be more profound than anyone thought possible. No one knows if or when they will be resolved to the deepest level.
