I guess it could make sense. Reading a bit more and it looks like the second is defined as a fraction (1/86400) of a day. Using 1/100000 wouldn’t be tgat crazy. But more than just fucking up all our softwares and time-measuring tools, that would also completely change a lot of physics/chemistry formulas (or constants in these formulas ti be more precise). Interesting thought experiment, but i feel that particularly changing the definition of a second would affect soooo mucchhh.
