So I goofed....I got a 40D several months ago and realized a couple of days ago that when I first set the date/time I set if off by one month.

It's not a huge deal but I like to have accurate info on when a shot was taken. Anyone have any suggestions as to how to bulk change the date on about 5000 images?

I assume I can only change the data in the .jpg's and not the RAW files, or can I adjust RAW also and leave that data in the .xmp sidecar?

(I have CS3)......

Thanks
