I recommend you read "The Fabric of the Cosmos" by Brian Greene.
He has a long discussion about why physics treats time as symmetric (past and present are the same to physic's formulas), but we "feel" the passage of time. Entropy, the tendency of systems to go from order to disorder, has something to do with our "perception" of time going forward.

Define 'proof.' A snapshot is an instant in time (by definition). A movie film is a series of exposures over an interval of time, frame by frame. If the movie is of a grandfather clock, the pendulum swings smoothly back and forth as the sun rises and sets and that is taken as an elapse of time. When time is divided too finely, like 'observing' an electron orbit an atom, it can get grainy because the location and speed of very tiny objects can not be known at the same instant.

time is just an experience...probably its an illution..perhaps ther r beings in other dimentions who dont comprehend the concept at all...anyway,einstein believes time moves with the speed of light

Watch and see how long your question remains on the board and you will see what time is. Look at the clock and you will see our measurement of time.

time is based on the assumption that the same thing can not be at two different places.
