This is the way to do it. One would think that batch photos would be the logical thing to use, but that sets the images at certain intervals apart which is pretty useless.
I tried the above method and even though it seems like you can only change one photo at a time, if you highlight more than one photo and use this method, it will shift all photo times accordingly.
There is also a helpful indicator that shows you how much the photo date/time will be shifted so you can double check that the time shift is correct (say you know that your vacation photos were taken in a time zone that is 15 hours ahead your home time).
