During the French Revolution, the government of France instituted a new calendar and time system. All the months were renamed, a week had 10 days, a day had 10 hours, an hour had 100 minutes, and each minute had 100 seconds. The changes didn't stick.
That French word is from a Latin word commodus
, which is simply com- and -modus. So unfortunately, Commodus doesn't even get his own word. Or maybe fortunately.Still 365 days a year, and midnight every day after 9:99.
Very rational, but also unpractical. On the other hand, there were different ways (non-sexagesimal) to count time around the world, before the European colonised most of the world and standardised the clock.
