The origin of the notion of time granularity probably goes back to the first efforts to measure time by human beings, and this really was a long time ago. From a carved eagle bone representing a lunar calendar found by archeologists, it seems that some 13,000 years ago Cro-Magnon men were the first to recognize the notions of time granularities and calendars.
