Have you seen Biff? It can do this and it will use your system's tzdb, unlike chrono. https://github.com/BurntSushi/biff

Thanks for sharing! I hadn't seen Biff – it's way more comprehensive than what I built.

nanji was just a quick scratch-my-own-itch tool for checking "what time is it in Tokyo/Dallas right now", but I can see Biff handles that and much more.

I'll definitely look into jiff for the system tzdb approach.

Appreciate the pointer!
