True GMT / UTC timezone

Is it possible to get a true GMT / UTC timezone added ?

All the GMT+0, including the one labelled GMT,GMT+0 seem to be affected by daylight savings, or am I missing something ?

I did not know the dedicated GMT+0 would follow daylight saving shift.
I also think most African countries do not change time, so I would guess picking some of the first options like Abidjan or Accra should work well too.

Yep you are right, I think Galaxy Watch Studio bugged out, I was using the sliders on the right to skim through the months and it was definitely changing +1hr / -1hr, however, after restarting the program, “GMT, GMT+0” behaves as I would expect.
