Made me wonder what other thing our civilization could consider starting back from scratch to adjust to our modern ways of living.
For example, do we really need time to be set as this 365.25d/24h/60m/60s system? We could have something more convenient/modern/metric?
Same for days of the week and daylight saving time.
I know it would be absolutely impractical and costly, but I like to entertain the idea of adopting a better system.
It explicitly intends that each solar day is split into 10 which is then subdivided into 100 and then again. This makes an ergonomic system for human usage although the fact that its time periods vary according to the day mean its not appropriate for science and engineering where consistency and accuracy are more important.
Doing away with time zones means arranging international meetings and travel is easier. Putting a full day on one click face lets you draw on the sun rise and set times and also lets you draw a days worth of appointments on the face. Since it's base ten addition and subtraction are trivial.
Anyway the numeric value is the same everywhere so it doesn't affect your time, it just affects the way your clock face is drawn.
If you shy away from it, any given point in your year's calendar will drift in terms of seasons. You see this in the around 354 day Hijri calendar, for instance.
(Edited: removed claim 365.25 is unitless. The unit is rotations/revolution)
As for number of hours in a day. 24 is very divisible which is better than say 10. You can divide it into 1, 2, 3, 4, 6, 8, 12, 24 without fractions.
As for 60 minutes and 60 seconds, these again are very divisible: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60.
The more interesting question, should we have chosen base 12 instead of base 10. It would of course be harder to count using your fingers.
No necessarily. 4 fingers * 3 knuckles per finger make 12, so you can count in base-12 using only 1 hand. I think the Sumerians (?) used that * 5 fingers on the other hand to count in base-60, resulting in our base-60 time system.
Whatever base we use for counting, and I can imagine arguments for senary decimal duodecimal binary or trinary, we should use the same base for counting time.
