    Even if the idea of time were our perception, it would still exist as a perception or concept.

    It does exist. If it were merely our perception than this would not work.

    Time does exist. My exam is coming up in 9 days.

    Now is not the best time to argue that time does not exists

    Surely, if anything, time dilation is a demonstration that there is no such thing as time in an absolute sense and that the illusion of time is based upon the subjective interpretation of observers?

    Not really. It suggests that time is a dimension that can be warped, as with space.

    Well yes, but relativity certainly challenges the conventional view of time as a linear progression of events. The concept of 'now', for instance, has no physical definition because time is necessarily attached to location in space.

    No because if time were based purely on your perception then you should spend the same amount of time when going at the speed of light than when staying on Earth.

    I'm sorry but I do not follow your logic. If the speed at which time is perceived to progress alters depending on the observer's position in space and the speed at which they are traveling, then this proves that concept time as linear and absolute must be erroneous.

    I complete agree with this.

    But why is time necessary for our evolution ?

    It proves that it is not linear and absolute, but it also shows that it exists. It gives us something to identify it as.

    Before I discuss whether the phenomena of time dilation proves the existence of time any further, I think you need to define precisely what you consider time to be. I suspect most people, if asked to define time, would give some vague description of progressive change, or of a constant 'flow' of events with a fixed direction. These definitions imply linearity, and as I've previously explained, no such linear progression exists beyond what we subjectively perceive as the change in observable values.

    In addition, it has been experimentally established that certain observed phenomena are not bound by our notion of time. The quantum superposition of subatomic particles as demonstrated by the double slit experiment, for instance, shows that particles can occupy all their possible positions in space and time simultaneously. This observation would seem to suggest that the common conception of time is a misapprehension.
