The current *time keeping system* is based atomic clocks. It's only
when you want to display this thing called "civil time" (so-called
because it causes very uncivil arguments) that you concern yourself
with astronomy, base 60, base 24, and other constructs.

Now, if you want to argue about a poor choice of standard, look at
so-called "Internet Time" that a Swiss watch company invented, which
divides a day into 1000 beats. Why use the day as your basis and make
it hard to convert to SI units reliably?
