I think this also ties into how conscious we are of time passing. For example if you stare at a clock, a minute can feel like ages. While if someone is actively engaged in something else, we tend to lose our conscious perspective of time without other external stimuli such as lighting. When I was younger, daydreaming during class could cause it to be over in almost an instant. If I constantly kept track of time while half-awake to avoid oversleeping, it often felt like it took far longer to pass. Which, with this in consideration also helps explains why solitary confinement is so tortuous, since it destroys a person frame of reference for the passage of time.
