I looked at the Guix recipe for tzdata and it seems nontrivial.  There
is compilation with GCC.  Therefore I fear using Debian’s tzdata from
Guix’s Emacs.  I suppose I will continue using Guix’s tzdata.  Indeed, I
recall having heard that Guix packages are not supposed to access files
from the foreign distro outside of a few locations such as the user’s
home.

Pardoned. :)
