For a polygons and polylines, you'll have to transform every point in every ring/path by adding a z value or changing the current z value to whatever you like.
I don't see a Created_Date attribute, but I assume that should be fetched if outFields = ['*']. In terms of transforming a timestamp into a height, or somethign that could be used as a height, I think you could do this by scaling your total set of timestamps from 0 to X ms where X is the difference between the smallest timestamp and the largest timestamp and 0 is the smallest timestamp. Of course you could use seconds, minutes, etc instead of ms.
