When you transfer the pictures from your camera to your PC, the date and time are saved on your computer as a part of the information that is stored with each image. You can't configure the photos through Sony Picture Utility to display the date, but you can use a picture editor from Software Informer database and add a watermark on each photo. In order to find out the date a picture was taken, right-click the file, select Properties and click the Details tab. The date is displayed below the Authors next to Date taken.
