I think that if you use the metric system you should develop a ten hour day - and a 100 minute hour - and a 100 second minute. Without that, Imperial units are best - right?
At least, you can easily divide an hour and a minute by 2, 3, 4, 5, 6, 8, 10, 12 and 15. Which is a little more annoying with a pint (...but who would divide a pint anyway).
