There is some evidence our bodies have split up the day into 16 parts: consider the 90-minute REM cycle. This suggests it would make more sense to try to use base-2. 4 bits of depth required to specify the 90-minute "hour". 16 bits of depth corresponds to a resolution of about 1.32 seconds. Then following the obvious pattern however "minutes" would probably be 8 bits of depth, corresponding to 5.625 standard minutes, so this is the most jarring difference. Of course then you wouldn't have clean divisions into 3, 5, etc. but it would be simple to calculate, notate, and reason about.
