Found this while doing some optimization of ls.

$ ls -l --time-style="+%Y %0"
total 61600

...
$ cargo run ls -l --time-style="+%Y %0"

Looks like this is known in #7687 (@tertsdiepraam, @Qelxiros).

So IIUC we just need to wait for the next chrono release and switch to new_lenient: chronotope/chrono#1693 .
