Maybe try this program. You need to have the camera set to the correct date and time (not trying to be funny there but it is the part needed if want everything right). It is Nakood and the program is Y.A. Photos Date Stamper (can't remember if just googled Nakood and downloaded it and then picked the Y.A. Photos Date Stamper out of its drop down menu or not. Basically you would choose your picture you wanted and enter it and then you can select size, color, etc. of the date/time to be printed on it (can akso choose location to print it). All this is kinda fuzzy trying to remember as haven't used it in a bit. I don't have my data set to show but by having everything correct on the camera it will just take it from the settings (I guess) that are ingrained(?) to each picture. Believe you can even do this to ones years old.
If need more help with it just yell and I can see if can find it. Was a thread on here or hags about it.
