Time is the measure of the duality between becoming and duration. Through mathematical equations, some physicists have denatured the concept of time. They have even gone so far as to assert that time does not exist and is merely an illusion. For some people, time does not flow. All of this stems from the fact that duration is subperceptible. Being subperceptible means that we first perceive the beginning, followed by a succession of instants, and finally, we perceive the end.
An illusion is a false perception of reality resulting from the nature of the stimuli involved. Time appears to be an illusion because we cannot perceive an entire interval in its totality—for instance, we cannot perceive a full hour all at once. It requires a sequential sense. Clocks measure the time of a specific interval, spanning from a beginning to an end.
In summary, time is the physical magnitude that measures the duration of changes (becoming).
