    I believe time does not exist, that it is just a concept of our mind. Therefore I don't believe it has definable characteristics, like matter and energy which are are very real, and therefore have definable characteristics.
    You have to be extremely carefull nailing down _exactly_ what you mean when you say you don't think time exists. Even if you doubt that time flows (which actually turns out not be so unreasonable), it seems very hard to claim that there is not some form of non-spacial variable that physical systems depend on that ties into to our psychological sensation of time.

    Thank you very much. I'm so glad more of an intellectual (and such a knowledgable person) could explain exactly what I have been trying to say so simply.

    Yes, they are 'time machines'.
    The GPS system (which is based of very, very exact timing) has to take the different speeds to time into account due to the altitude difference of the satellites and the ground.
