How can we get decimal time established?

So how are one divide a year up? It doesn't divide into ten at all.

Except it does. The French Revolutionary Calendary made 12 months, granted, but the point is that one week equals ten days and one day equals ten hours. With scientific knowledge that one day is approximately 23 hours and 56 minutes and one year is approximately 365.25 days, decimal time can be used to better express these facts, in addition to adding to the metric standard.

Out of curiosity, is this going to require a reworking of the circle into something decimal? 100 degrees instead of 360?

In theory you could do that, but just because you make time decimal doesn't mean you have to make the circle or other mathematical formulae decimal.

Mathematically, yes you can express these two values as a function of ten, but not as a function of 10 and each other you are going to have some sort of remainder. Which negates decimalization only other real advantage (the first is standardization which Indicus addressed) ease of unit conversion.

Secondly, decimalization measurment is not an "inherently better way" to express values only more convenient because we use a base 10 counting system, and are taught that first. If taught properly there is no hindrance from using a non-metric system other than the for mentioned standardization or quicker unit conversion.
 
Looks like I was mistaken. It seems the 24-hour clock really was the only system except when ancient China broke the day into 100 marks, then they changed their mind and broke the day up into 12 units, and then 24. So a decimal clock will be harder than I thought. And I had thought that there was a metric version of the degree that pilots tend to use, but it seems that what I was thinking of is the gradian, which is 1/400th of a turn.
 
You would have to have someone other than the Sumerians FIRST invent the idea of time keeping and civilization as we know it.
 
It seems the the Chinese had a metric system for a while but the 24-hour systems seemed to catch on in every culture that has any power thousands of years ago. If anyone can find any information to contradict that, I'd be happy to hear it. There were systems where the hour changed its length depending on the time of the year, but it seems there were always 12 hours during daylight back then.
