Time is never going to be easy to decimalise, since days, months, and years are all natural periods and not so easy to change.
Maybe once we have left the Earth and spread out into the solar system and beyond, there will be no reason to keep Earth time, and we'll just use Unix time, and stick to seconds, kiloseconds, and megaseconds. (Hopefully in the next few gigaseconds.)
