While time itself might be nothing more than a variable used to measure motion, the passage of time seems to be a matter of perception and a function of how much time one has remaining and at their disposal.
In other words, whether a task takes alot of time to complete is a matter of perspective and a function of how much time is left to complete the effort. For instance, we all know that sometimes seconds seem to take hours to pass and at other times hours pass by like minutes. As for another example of the relative weight of time and in keeping with the stated perspective theme, to schedule something for next week might seem soon to an adult while it might seem forever-away for a child.
