how to edit LC_TIME variables: date_fmt, d_t_fmt, t_fmt?

I also noticed that the the default date format for bash is different for “root” verses “user”.

root displays the traditional date format “Wed Jul 14 19:00:53 EDT 2021” (the format I want)
while user displays the new date format “Wed 14 Jul 2021 07:00:06 PM EDT” (the format I do NOT want)
