Notes

This is a rare clock made just after the suspension of the provision for decimal hours on April 7, 1795, while the pro-vision for the revolutionary calendar was still in effect for the next ten years. After the French Revolution, a new digital system was adopted, affecting weights and measures as well as time. 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. There-fore, the provision for decimal hours was suspended on April 7, 1795.
