Decimal Clock

In 1793, the French National Convention issued a decree that the day would henceforth be divided into 10 hours, each of 100 minutes, each of 100 seconds. Though the idea proved unpopular and was later abandoned, a number of decimal clocks still exist as curiousities.

This clock is a JavaScript implementation of the idea. Each “second” is 0.864 standard seconds long. To see the standard time superimposed on this clock, press any key.

The source code can be found in the clock club repository.
