Relevant manual page is here: https://docs.digikam.org/en/post_processing/metadata_editor.html#date-and-time On Edit Metadata -> Time&Date, there are checkboxes "sync XMP Creation Date" and "Sync IPTC Creation Date". It is unclear what is synced towards what. Even the documentation does not explain this. 2 questions: 1) If I check the box, is the Exif-date synced TOWARDS the XMP-date or FROM it? 2) If the corresponding box is checked in the XMP tab and the dates are different, what happens? Who wins? The first can be solved by one single word: "Sync Creation date TO XMP" or "Sync Creation date FROM XMP". When boxes are checked on multiple tabs, I do not know a quick solution. I could imagine that checking the box on one tab unchecks the boxes on other tabs but that is unfriendly - the user does not see this happening. Perhaps a warning? "You have checked the same box on the other tab, choose only one" ?
