Your camera may not have that feature, not many do any more.
Looking at the User Manual I can not determine if it does.
You can print the date/time on the face of the photo by using a Picture Bridge Photo Printer.
See page 75 of the User Manual for details.
All digital cameras do include EXIF information in the picture file.
The date and time the picture was taken is in the EXIF information along with much more information about the photo.
