I think I found a bug. In any format that I try to touch a file with the
date 2022-09-11 at 00:00, touch says I'm entering an invalid date
format.

    $ touch -t 202209110000 algo
    touch: invalid date format ‘202209110000’
    $ touch -d 2022-09-11T00:00:00 algo
    touch: invalid date format ‘2022-09-11T00:00:00’

If I change date or hour it works flawlessly

    $ touch -d 2022-09-11T01:00:00 algo
    $ echo $?
    0

In Santiago, Chile, that timestamp does not exist. Is your timezone set 
to Santiago time? That would explain your symptoms.

I am, but I don't understand why the timezone would make a time not to
exist... What am I missing?

CC = 20
YY = 22
MM = 09
DD = 11
hh = 00
mm = 00

Uh, oh, it's daylight saving time change... never thought of that. Good
catch!
