Coordinated Time

As with Harold Lloyd, the star from the days of silent movies, our lives literally depends on the clock. For over 150 years, clocks have been governing our daily life at a pace with global machinery. Punctuality in terms of people and merchandise is one of today’s magic formulas for economic prosperity. For this reason the historian, Lewis Mumford (1895-1990), called the clock the “key machine” of the industrial age.
