How do I get a locale or timezone used on Venus?

In this answer , Stéphane Chazelas uses a UVC timezone and vs_VS locale. When I asked about them, the reply was that these are the timezone and locale used on ... Venus. I'm not entirely sure whether the response was tongue-in-cheek, and it might well be something bespoke. But I'm interested in trying out these settings, so I how can I do that on Arch Linux or a recent Ubuntu release, without having a friend from Venus?
