It does, thanks, but I'm in a bit of a pickle there because this packagge needs, for reasons outside of my control, to be deployable on a multitude of host (non-GuixSD) linux distributions, and as a docker container. In those cases, I can't expect the timezone data to be up to date or to be there at all. Even if I list tzdata as a dependency, the host system's TZDIR will not point to it. I understand that if I regularly guix pull and guix package -u, then the tzdata package will be kept up to date. Is that correct ? If it is, then I need to rebuild the .tar.gz and the docker image every so often, and this problem would be solved for the foreing distros as well. Thanks for alerting me about this ! Cheers, Edouard.
