I have been through the process you describe above, many times. Reason for this exercise is my wife and I both shot the wedding. Cameras were time and date synced so that we could dump the photos and sort them by creation time. Problem popped up when she went through and edited the files which resulted in new dates and times. Should have sorted and renamed files before doing any editing. Live and learn.
Thanks for your help.
