How do I set the date time structure to the correct timezone?

I am trying to get the date modified of a file, but the date time is one hour or two hours behind the actual time modified.

FFileManagerGeneric fm;
	const TCHAR* Filepath = *Path;
	FDateTime thetime = fm.GetAccessTimeStamp(Filepath);

Didn’t do it with c++ but just used the asdatetime(UTC) node, because i only needed the text anyway
