You can manipulate that too. EXIF is just text in the 'header' region of the file over the image data payload. I edit EXIF most every day when working with scanned film JPEGs to create images that have the rich EXIF as if from a digital camera, adding shooting dates, film ISO, camera and lens data, etc.
I know that, but the OP has access to the date & time if he so chooses to add it to the image area. As long as it is only in his possession he has the knowledge that it has not been manipulated.
