bug#36870: was: date bug -- really locale bug or ??

[Bengt Richter]

Hi all, following up on myself, sorry I lost my copy of
my original, so this does not contain any quoting, but
this can stand on its own as a new problem statement.

Problem should go away if I can get locales working,
but despite trying what purportedly has worked for others,
no luck. I hope it will be obvious to someone from the below ;-)

$ ### that warning -- "guile: warning: failed to install locale" might be a 
clue in that

emacs's M-x shell ...

$ ### does something depend on ttyN vs pts/N ?? don't think so, but maybe some 
env gets lost in pts start?

I put

export GUIX_LOCPATH="$HOME/.guix-profile/lib/locale/"
export LC_ALL=en_US.utf8

in both ~/.bash_profile and ~/.bashrc
and still no joy
 
I'm wondering whether I have to reboot, not just log out and back in,
to get locales into effect. Have been trying and searching, but something
is eluding me ;-/ [later, after rebooting -- nope, reboot didn't do it :( ]

(Hm, guess I ought to clean out some generations)

Any ideas appreciated. Am I the only one seeing this?
I first noticed because who -b gave me UTC time instead of local time.

Thanks.
