So, after tinkering with setting and fresh install of Libreelec this is what i found.
EPG will show correct time, when EIT is on UTC. Which is kinda wrong, Slovakia and a majority of EU has right now +2 zone. If i try to set this to match server (local) time, it will show everything 2 hours back.
So you can mark this as resolved with a lot of question marks... srsly what the hell
