I fall asleep at night in the dark. I wake up in the dark. During that time, I have been unconscious.We perceive the passage of time (changes), but not intervals.
Between being unconscious and being in complete darkness, I cannot perceive any changes - and yet time has passed.
Therefore, time is not simply the accumulation of perceptible changes. It marches on whether or not I perceive changes or am even conscious.
