The date you are looking at "IS" the File Creation Date, IE the date the exported file was created. That will always be the Date the File Was Created.
It is not the Capture date which doesn't change. Two Totally different things.
It should be working the same way in Lightroom 6 as in Lightroom 4. In both versions, whether the original Camera EXIF Capture Date is exported depends on how you set up the Export dialog box:
If you want the original Capture Date to be included in the export, set Metadata to "All Metadata" or "All Except Camera & Camera Raw Info".
If you don't want the original Capture Date to be included in the export, set Metadata to "Copyright Only" or "Copyright & Contact Info Only".
Thank you! That pretty much worked. Odd though, the minutes were off by 8 minutes (ahead) in the export, than the raw file. Any thoughts on that?
