When:

1. Date locale format in terminal is set to:
LC_TIME="en_US.UTF-8"
2. When "date" command is issued, either as "date" alone or "date +%c"

The output date is in the incorrect format.

For example, at the time of this bug, the output is:
Sat 02 May 2020 07:44:45 PM MST

In common United States date format, it should read
Sat May 02, 2020 07:44:45 PM MST


Reproducible: Always

Steps to Reproduce:
1. Set date format environment to "en_US.UTF-8"
2. Issue "date" command or with "date +%c"
Actual Results:  
Date outputs in incorrect date format per United States standards. IE:
Sat 02 May 2020 07:44:45 PM MST

Expected Results:  
Date should output per United States standards. IE
Sat May 02, 2020 07:44:45 PM MST

This is likely an issue with the way that locales are handled.
