I have a SharePoint list with different items containing a start & enddate.

If I connect PowerApps to this SPlist and fill a gallery with the same items I get the times +9hours.

I checked the site language settings, language settings in my O365-profile & PC language settings. It is all UTC+1 (Belgium is where I am). I then tried to change it in PA to Text(ThisItem.Startdate;DateTimeFormat.ShortDateTime;"nl") but that doesn't help either.
Anyone any other explanations or solutions?
