I’ve set up a local Grafana instance on a Windows server. The server’s time is CEST, Windows Server 2016 time is CEST, database (SQL Server) time is CEST and browser time is CEST. Grafana is set to “Local Browser Time”, but the generated Unix timestamp in SQL is UTC and not CEST.
You need to explain in more detail exactly what problem you are seeing. Often such problems are caused by data in the database (assuming you have one) being stored with local time instead of UTC. The data should be stored with UTC and then the browser will apply the local correction as appropriate.
