>but almost no one advocates for metric time In physics it is not rare to see seconds used, with scientific notation, for measuring periods much longer than an hour. But for practical purposes it is very nice to have units which are easily divided into thirds and quarters, which is possible in base-60 but not base-10. This is equally true for angles, which also tolerate eighths (45 deg) and ninths (40) of a circle. The impractical division of liters to 1000 milliliters has after all given us a couple of incompatible reifications of metric measuring cups and ugly numbers in recipes. 960 = 64 * 5 * 3 might have been nice if we were willing to tolerate a "metric quart" which differs from the liter (alternatively, a "baker's milliliter"), and recovers the teaspoon, tablespoon, ounce, cup, and pint in round numbers.
