Have you been thinking of the induced cost (around 1000 billion $)

Who would pay ?

And practically :

Clocks and watches replacement (What about Big Ben and others ? )

Reprogramming BIOS or human time clocking on PC.

TV and radio station should fix up the problem.

Redefine a reference second.

Enterprises should have to update their payment bulletin.

Redefine geographic meridians

And what about the travels (planes, boats... ? ).

Someone was talking about decimal time where the second is shortened by
about 15% allowing 100 secs/minute, 100 minutes/hr, 10 hr/day.
