Human beings experience time in an personal and context-oriented manner. "Human time," time as human beings experience it, must be distinguished from "mechanical time," time as a clock measures it, and the interrelation between the two must be considered. Regardless of how much attention human beings pay to the regular intervals of mechanical time, their experience will always be relative and individual. Even one, incredibly attentive to the movement of mechanical time, can still only experience time through his own subjective point of view - any attempt to organize time into a systematic entity is merely an act of convenience.
