locale.conf exists yet perl does not care

linux 4.12.14-lp151.28.36-default x86_64
PERL v5.26.1

PERL has begun to complain about missing locale settings. Below is what PERL says, the command “locale”, and the contents of /etc/locale.conf. I do not see what the problem is.

I have the same configuration on another computer; it does not show this problem.

$  perl

LC_TIME value is wrong. You probably want the same en_US.UTF-8 as for other categories.
