Hi , jochendecraene 

It usually occurs when  user has different time zone other than SharePoint Time Zone

It seems that powerbi currently returns dates from SharePoint items in UTC, unless you apply a transformation.

I will suggest you to converted the date time values to your home time zone  by adding offset  hours to UTC date time values.
