What are you asking about here?

Are you talking about the "decimalization of time" after the French revolution in 1789, when they created a new calendar, introduced clocks with 10 hours per day, etc? In which case I don't know the answer, but it should be in some history websites.

Or do you mean the fact that some European countries write "comma" instead of "point" and vice versa, so the number "one million ... point eight nine" is written 1,234,567.89 (UK, US, etc) or 1.234.567,89 (France, Germany, etc).
