You cannot really make all the time units a multiple of 10 to each other as a day, months and a year, for example, are defined by external factors.
You could perhaps change seconds so a day would be exactly 100k seconds, which would make seconds slightly shorter than they now are but that wouldn’t really change the fact that a year is 365.25 days and that a month is either 27.32 or 29.53 days depending on how you measure it.
A day is the spin of the Earth and a Year is the orbit of the Earth, but months are completely arbitrary because we (Western world) don’t use Lunar cycles for months.

Let’s first establish decimal time, then we can talk adding thrusters to Earth to adjust its rotation…

There’s no reason we couldn’t have 10 months.
Except a second is also already defined by external factors so making it shorter actually messes up ALL other SI units/compound auxiliary units…
The MS has a solution for that. Days, years, weeks… are not part of the system. They are understood and the conversions accepted, but that’s it.
