Time can be defined as a method by which one moment is compared to another. Let us explain this with an example. For instance, if anyone taps an object, he hears a particular sound. When he taps the same object five minutes later, he hears another sound. He perceives at that point that there is an interval between the first sound and the second and he calls this interval time.
Yet at the time he hears the second sound, the first sound he heard is no more than a figment of his imagination. He formulates the concept of “time” by comparing the moment in which he lives with what he has stored in his memory. If this comparison is not made, there can be no concept of time.
