Thanks for the hint, the correct spelling does work.

I've tested Guix System.  If you install tzdata locally, don't forget
to set TZDIR in your shell profile to make Emacs find it.  The
following command fails to resolve Brazil/East:

    guix environment -C --ad-hoc emacs tzdata -E TERM -- emacs

The following command does not fail to resolve Brazil/East

    guix environment -C --ad-hoc emacs tzdata -E TERM -E TZDIR -- emacs

Note: the above assumes, that `guix build tzdir` produces $TZDIR, which
in Guix System, it does.  In particular, my earlier comment, that Emacs
uses Guix' tzdata seems to be wrong – it should use whatever you set as
TZDIR.

Regards,
Leo
