Russian Standard Time bug

Hello, tooltip for "Russian Standard time" says GMT+3 and it's correct, but when i choose it, it's actually GMT+4. For example "(GMT+3) GBT Standard time" works fine for me

Similar issue. My real time zone is GMT+3 now (Eastern Europe), which by the way is not even on the list to choose. This way when Europe rotates clock 2 time a year, we also need to change time zone.
Secondly when I choose other GMT+3 zone, then it shows 1h difference.

P.S. After going to settings and saving same time zone again, it now shows correct time.
