There's no way to have it display on the pictures, but the date and time (and lots of other data) is recorded with the picture. If you want it to display when you print, you can setup most softwares to do this. If you print from the camera, there is a way to have it print date/time on the pictures, but I've never found anyone who actually prints directly from a camera. If you take it to a lab or retail store, ask them to help you get it on your printed photos. The photo kiosks can read the date from the file and print it out. Sometimes they print it on the back also.
