I was hoping for something more automated. Where I could either search for pics where the iPhoto time does not match the EXIF time, or a something where I could batch reset the time on a large group of pics. The problem is that I suspect I have this problem elsewhere in my library, but I have too many pics to be manually clicking around to see if the time is right.
I'm not sure how you have changed the date/time in iPhoto - but using smart albums you can identify photos form a specific camera - or many other attributes
in Events view the default sore is by date/time so I would expect the problem photos to be grouped together -- and in Photo view you can select several different sorts and by truning off show event titles you can view all of your photos as a single group
I'm not clear on whart you found or what you are expecting but the way to modify the contents of the iPhoto database is to only use iPhoto to do it - never make any changes of any sort directly to the files in the database
