Metric time and dates notably fail to work with the observed motion of the Solar system. The time metrics we use are determined by the rhythms of the Earth, Moon, and Sun. Metric time offers no benefit. (And for the record, Napoleon tried to decree decimal dates and times, but even the French weren't having any of that crap...)
