date behaves differently than coreutils when no argument is passed, if the goal of the project is to behave a 100% like the gnu coreutils, this should be fixed. here are two examples , it should be pretty easy to reproduce unless it's a weird problem with both my systems (manjaro and endeavour os)

Exemple 1 :

$./date
Fri Jul 29 09:09:10 2022
$date
$Fri 29 Jul 2022 09:09:12 CEST

Exemple 2 :

$./date
Fri Jul 29 16:40:39 2022
$date
$Fri Jul 29 04:40:40 PM CDT 2022

I looked at the code and i think it's caused by the chrono dependency not correctly detecting the current locale when formatting with %c. not sure about that though.
