Frankly I don’t get the GMT face. No matter which timezone I choose, the red hand always points at the same spot, just the number changes.
You’d assume it’s a 24hr clock where midnight is on top and 12pm is on the bottom but it does not seem to be the case.
EDIT it seems the GMT scale is rotated byt the amount of hours it representa, so if the timezone difference is 6 hrs, midnight will be 90 deg to the right 🤨
