Have you ever had one of them say "I'm in Beijing, but you're only offering me Shanghai"?

Nothing obliges you to use the tzdb identifiers rather than, say, names that might not require knowing how tzdb region IDs are chosen, e.g. "China" as the name for Asia/Shanghai (and something else, such as Xinjiang or Urumqi, for Xinjiang time), other than your platform being *so* small that even a mapping from "names we offer to the user" to "tzdb region IDs" won't fit.
