I figured out what's going on here: changing the timezone requires poking two systemd services:
- org.freedesktop.timedate1.set-ntp
- org.freedesktop.timedate1.set-timezone

Both require authentication, so you're asked twice. The only practical way to improve this is to ask distros to ship polkit rules that suppress one or both of these by allowing them to proceed without authentication. I've written about this in https://community.kde.org/Distributions/Packaging_Recommendations#Polkit_configuration and notified distros about it.
