Your relative visual as you said is refer to the relative data slicer visual showing below picture?
Data models in Power BI do not include time zone information. The slicer and filter are always based on the time in UTC, so if you configure a filter in a report and send it to a colleague in a different time zone, you'll both see the same data. However, if you aren't in the UTC time zone, you might see data for a different time offset than you expect.
