Is there a metric system for clocks? The day (24 hour period) would be divided into 10 (hours), 10 (minutes)

Question

per hour, 10 (mini-minutes) per minute, 10 (seconds) per mini minute, 10 (mini-seconds) per second.

Is that already done somewhere?

The year could also be divided into ten months?

What is so special about 12?

Answer 1

QUOTE:

The origins of our current measurement system go back to the Sumerian civilization of approximately 2000 BC. This is known as the Sumerian Sexagesimal System based on the number 60. 60 seconds in a minute, 60 minutes in an hour - and possibly a calendar with 360 (60x6) days in a year (with a few more days added on). Twelve also features prominently, with roughly 12 hours of day and 12 of night, and 12 months in a year.

QUOTE relating to degrees in a circle:

...360..was probably adopted because it approximates the number of days in a year.

QUOTE relating to how one degree may have came about:

Ancient astronomers noticed that the stars in the sky, which circle the celestial pole every day, seem to advance in that circle by approximately one-360th of a circle, i.e. one degree, each day.

Basically, the two pages linked below are claiming that clocks are based on the movement of the Sun and the stars, which makes sense because ancient people would have used those to determine the passage of time.

Answer 2

They tried it and it didn't work.

Answer 3

No, a clock is based on a 360 degree system. The Earth is always spinning. 180 degrees is half the circumference of the earth, which is day, and the other 180 degrees is darkness. (180 x 2 = 360). When the earth turns one degree, one minute has passed, 60 minutes or one hour is 60 degrees and so forth. This is one-half of a system used to find our co-ordinates on the planet, like I am 6 hour, 10 minutes, 3 seconds (latitude), by 130 degrees (longitude). Easy as pie... It can not be done anywhere, at anytime, because there is not a measuring difference, i.e. C to F, Yards to Meters, it's timing is consistent and precise most of the time. It can not be divided in to 10 months, because the earth takes one year to travel around the Sun. That's where 12 come into play. 12 months is a year, and there is 12 hours of day, and 12 hours of night...  Taa - Daa!!!
