Back in the 1970's I tried to come up with a metric time system by breaking a day into powers of 10. A centiDay was 14.4 minutes.

I realized it would never catch on, because a 30 minute TV show would have to fit into 28.8 minutes, and the only way to do that was to lose a couple of commercials. Never gonna happen.

Back in the 1790s some Frenchmen did the similar thing but, despite not having TV and commercials it still did not catch up even in France.
