I've always entertained the thought that our time system (24 hours, sometimes regarded as 2 periods of 12 hours, 60 minutes and seconds etc.) is an inefficient and unnatural concept.
Besides the computational inconsistency and uncertainty of time declarations, I mostly get frustrated by the fact that none of the units we're using actually corresponds to anything useful.
By that, I mean that a minute is way too fine and an hour way too blunt divider. I've noticed that when I consider my time, it goes in chunks of about 15 minutes. So, a quarter seems a nice choice with additional advantages.
Consider the full day. It consists of 24 hours, which is 96 quarters. If we can approximate it a bit and divide the whole day into 100 parts (or 1000 to be slavishly following the decimal system), we get the quarters to be about 14.4 minutes long, which is roughly speaking what they are today.
The consequence of that would be that half a day is 50 units, a workday is about 30, you wait for a friend for 1 unit before you get PO'ed and the shower takes 2 units, whereas a movie is between 6 and 10 units.
What would be other advantages to such a shift? What would be a disadvantage?
