Related to this issue , I've been struggling with time zone issues in Power BI. I've tried many solutions and have also involved other PBI specialists - all has failed so far.
In my case, PBI service adjusts to UTC 0 time columns originating from Outlook emails as data source. Time columns that do not originate from Outlook (text based), are untouched by PBI service and are displayed correctly (unaltered). This is clearly a pesky issue that I think should be configurable in Service: "use x timezone and observe daylight saving time for that time zone". Much like Outlook itself can handle.
Has anyone else come accross this problem of time data altered depending on data sources and has a fix for it?
