4.1.1: timezone test fails

Hello,

While updating the package to 4.1.1 in GNU Guix, I've noticed the following test failure:

The build happens in a containerized environment where there's no /etc/timezone file.

The zoneinfo dir is explicitly configured as zoneinfo_dir : /gnu/store/7pjzwj9d4fnyzp9x7k8cc4hazypyrk0p-tzdata-2022a/share/zoneinfo.

Thanks.
