The revolution changed vsё

During the Great French Revolution changes have affected virtually all aspects of life: even the Republicans have developed their own special calendar and the decimal system timekeeping.

Decree of October 5, 1793 the first year in the country was introduced, under which day divided into 10 hours, an hour at 100 decimal minutes and minutes to turn - 100 seconds.

The main advantage of such a measurement of time before all the usual duodecimal system is the ease of notation and recording time, since it is based on the decimal system, which allows you to record the testimony of the time as a single string, reminiscent of a decimal fraction.

This facilitates the processing capabilities and reading time information, which theoretically could be used, for example, in modern computers, but unlike, say, the republican calendar, the decimal system is not widespread, and already in 1795, the year of her abandoned. < br />
By the way, decimal time, however, slightly different from the French system was used in ancient China along with duodecimal timekeeping. The French, apparently, borrowed its system from the ancient Egyptians, who also shared the day is 10 hours, the clock for 100 minutes, and so on, which confirms the ancient truth: everything is new - is well forgotten old, including the time. < br />
