Why (or why not) add a time-date stamp?
The most obvious purpose of a time-date stamp is as a memory aid, a perfectly valid purpose. However, many photographers point out that this is also easily accessible via the EXIF data—that is, the digital documentation of not only when the picture was taken, but also the settings with which it was taken, including ISO, exposure and more. There are numerous programs out there for looking over EXIF programs without anything nearly as intrusive as a time-date stamp, including most popular digital editing software and viewing browsers.
Some photographers enjoy time-date stamps because they function as a watermark, a stamp that proves that they took this photo and that they're the ones with the right to it. In the digital age, it is very easy to steal photos and claim them as your own on the Internet, and this is one way to prevent that. However, time-date stamps do not actually include your name as the photographer. If you are adding a time-date stamp for the specific purposes of a watermark, it might be better to create one with your name on it instead.
Other photographers find them incredibly distasteful, seeing them as intrusive, usually a ruining a perfectly beautiful photograph. If you don't have a version of the photo saved without the time-date stamp, you will probably have difficulty fully removing it later, even with the aid of powerful digital image editing programs—a real problem if you want to print it out and frame it.
