I posted about a problem over in the Lightroom forums, but seeing as I found a solution, I figured I'd post about both here on Digital Media Thoughts in case anyone runs across the same issue. Here's my original post:
"After a lot of testing I've nailed down a serious flaw with Lightroom, and I'm wondering if people have any sort of solution, either from within Lightroom or externally. When Lightroom is used to export JPEGs, the exported files have the correct Image EXIF data stamped in the Date/Time Original and Date/Time Digitized fields - it matches the date/time of the RAW file, which is exactly what you'd want and expect.
What it doesn't set correctly though is the JPEG file Created, and file Modified dates - they are set as the date/time the JPEG export was done from Lightroom. There are many applications that sort based on the last modified date of the JPEG, and it's illogical that Lightroom wouldn't have the JPEG file metadata match up with the EXIF data. I can't think of a single scenario where you'd want to have two different time/data stamps in the image that you just exported.
Using ACDSee I can batch change the JPEG file Created and file Modified dates to match the EXIF data. It's an added step I shouldn't have to do, but I can do it. What I *can't* change in batch mode with ACDSee is the Camera Date/Time time - which, you guessed it, is stamped with the time that the JPEG was *created* during the export, not the time that the camera was set for when the RAW file was captured, which is what it SHOULD be set to. It should be stamped with the EXIF date/time original data. I think I already know the answer to this, but is there any setting in Lightroom that addresses this issue? I've seen others recommend EXIFtool but using a command line tool isn't what I consider a reasonable suggestion. Are there any other tools that might help me here?"
And then, 32 minutes later, I had it figured out. ;-)
"I'll answer my own question: for some bizarre reason, ACDSee has a way to change the Camera Date/Time metadata field but it's not found under the Batch Adjust Time Stamp function. Idiotic. The way to fix the problem I'm describing is to use ACDSee 9, select all your images, select Tools > Batch Set Information, then set the Date/Time (this is actually Camera Date/Time) to map to EXIF Date/Time Original, and let it rip. I tried Microsoft Photo Info and it didn't change the camera date/time stamp, and I also tried AttributeMagic Pro, and it was clearly designed by a programmer and not a normal human being - it was impossible to quickly figure out."
