Exiftool works on any image file.
One thing that might be interesting (as in it could make life difficult) is if you have the NEF file and on occasion simply extract the embedded JPEG for use. That embedded JPEG will have the original date/time stamps. If you really want to do it... I'll show you how to extract the embedded JPEG, modify the dates, and then put it back into the NEF file with the new dates. It's a tedious task...
I have taken a quick look at Exiftool. It looks like it will be the one that works for my situation. I will report back how it works out. Thanks
