Notes Tardy lists Farjaire in Paris at the Rue de Bourgogne between 1806 and 1820. After the French Revolution a new digital system was adopted, which affected weights and measures as well as time. The entire system for the measurement of time was changed. The 24-hour day was divided into ten hours, each having 100 minutes, each minute being subdivided into 100 seconds. Thus, for example, 12:30 PM was 5:20:83.3 in decimal time. The decimalization of time was introduced on November 24, 1793. Whereas the new standards for weights and measures were relatively easy to implement, the new division of time proved impossible to enforce because the traditional system was too deeply ingrained in people’s minds.
