Unfortunately, there is no easy way to decimalise time for human use. If you make it useful for humans, it doesn't sync well to a day. If you make it sync to a day, the resulting units are awkward for the human mind.
Amusingly, for computers, time is decimalised! UTC is a fully metric time. It's just simpler to constantly remap to and from UTC to a user's time, than to train the user to use UTC.
For computers, Unix time is in binary. But yes.
However, humans can get used to longer/shorter seconds, minutes and hours. Arguing the opposite is like saying the meter would never work because it doesn't have a human body relation like feet. The problem is the sheer amount of documents, equipment and SI using the 24/60/60 system, and the indivisibility of 365.24.
The divisibility of 60 is useful, too. It has 1, 2, 3, 4, 5, and 6 (plus any combination of the above) as factors making dividing time a relatively simple operation.
