For example,
60 seconds = 1 minute
60 minutes = 1 hour
24 hours = 1 day
7 day = 1 week
29-31 days = Month (approx.)
365/366 days = year
It’s like for the imperial measurement of distance, where 1 mile = 5280 feet…
Edit: just to clarify, I’m more or less keen towards any consistent, decimal-based measurement systems like base-10 or base-12.
Decimal time rule!
Funnily enough, Asimov novels sometimes feature decimal time clocks.
Revolutionary calendar in the early French revolution was decimal too : 12 months of 3 weeks of 10 days. 5 or 6 days at the end of the year for vacations. And they used decimal time too.
It was wildly unpopular. I think the decimal time was removed after a couple of years. Napoleon removed the decimal time.
I have both on a app on my phone, just for fun. You can easily find apps for that.
