Guix Emacs does not get "America/Sao_Paulo" timezone by name |

Hi all! I use Guix on Debian bullseye¹. My Emacs is a Guix-installed
emacs-next with a package transformation option to use the latest commit
from the master branch. It works fine except that it wrongly evaluates
the following function call:
(current-time-zone nil "America/Sao_Paulo")
It returns `(0 "America")'. And I have verified that the same bug also
occurs on plain Emacs 27.2 (also from Guix).
Last time I tested in a manually compiled Emacs 27.1.50, I got the
correct result: `(-10800 "-03")'. Also I have just tested on someone
else’s notebook---Emacs 26.3 from Ubuntu---and it too returned the
correct result. I have not tested other timezones.
Thank you for your work in GNU!
¹ I intend to migrate to PureOS for better free software ethics.

Corrected your xsetroot invocation there :P

It turns out this issue is actually related to another issue of Guix'
Emacs on foreign distros, which is it not finding timezones. Since
I've found a permanent solution to both, I will close that bug and pat
myself on the back for doing so.
The main issue here is that foreign distros with systemd really cut
down on their use of environment variables, whereas Guix (System) makes
prominent use of them. In the case of the other bug, TZDIR was unset,
in the case of yours it was XCURSOR_PATH.
Writing an override configuration file with the following contents
--8<---------------cut here---------------start------------->8---
# ~/.config/systemd/user/gnome-shell-x11.service.d/override.conf
[Service]
Environment=TZDIR='/usr/share/zoneinfo'
Environment=XCURSOR_PATH='/usr/share/icons'
--8<---------------cut here---------------end--------------->8---
fixed this for me, although I should specify that I previously only had
TZDIR set and bound XCURSOR_PATH interactively in the shell (I am
typing this just as I found the fix and haven't yet had the opportunity
to restart my X session).
Now one thing I don't quite get is the interaction with GNOME Shell.
With my current setup as detailed above, Emacs inherits whichever
cursor was set in GNOME at the time of launch for the entire process
duration -- i.e. even if the corresponding GNOME setting changes.
I'm pretty sure in your setup with xsetroot there's nothing else
setting the cursor, so it ought to be displayed correctly after that.
If not, you might have to play around with cursor themes in other ways
(refer to [1]).
