The time of production, commodity-time, is an infinite accumulation of equivalent intervals. It is the abstraction of irreversible time where all the segments of the chronometer must only prove their quantitative equality. This time is in reality exactly what it is in its ex changeable character. It is in this social domination by commodity-time that "time is everything, man is nothing; he is at most the carcass of time." (Poverty of Philosophy). It is devalued time, the complete in version of time as "the field of human development."
