> So unlike our measures of distance, weight, etc, our divisions of time have been fixed (mod a factor of two) for over five thousand years.

Our measures of distance were more-or-less fixed too. Decimilisation of time is as bad an idea as decimilisation of distance, weight and volume.

Really, we should convert to a different default base. I suggest twelve: it has more factors and more repeating decimals are non-repeating duodecimals.
