@natevw @wezm It’s interesting to see the Amiga Workbench one (from v2.0 onwards, but the attached screenshot is from WB 3.1) where they just got you to select how many hours past GMT you were on the map, and your country / language were in different fields on the screen. You had to use the map though, there was no dropdown listing all the timezones.
Sucks if you were in an Anglophone country not represented in the list (eg. Ireland, New Zealand), you had to choose Great Britain or Australia, or leave the default as United States. Switzerland got a good representation though, having Schweiz, Suisse and Svizzera represented in the Country field.
