Foreman » Installer

Original post in support forum: https://community.theforeman.org/t/date-used-by-katello-certs-check-should-be-formatted-correctly-by-program/24527

Problem:
when foreman-installer runs, it runs katello-certs-check as part of the run, which in turn runs some date check. The certs-check completes successfully and everything is fine, but theres always an error that gets printed on my system due to being set to Icelandic locale:
date: invalid date ‘júl 20 14:36:21 2021’

Expected outcome:
Date command used by katello-certs-check should be locale-agnostic, like using standard iso format and not relying on servers locale settings

Foreman and Proxy versions:
“Error” has popped up for a few versions now, latest while upgrading to 2.5 / 4.1
