This conversation has been merged. Please reference the main conversation: Lightroom Classic: Edit Capture Time issue - Need a way to set all photos selected to same date & time
Here are two photos that were taken in May, 1925. One of them has the wrong date.
I try to adjust the dates of both of them
and afterwards, Lightroom has marked one as having been taken in the 19th century
I have run into many issues with setting the dates for historical photos, but I thought I had figured this out. (It would be nice if Lightroom had the facility to set the XMP metadata that correspond to the date of the image vs. the date that this copy was made, but I have never been able to make that work). But at a minimum, Edit Capture Time "Adjust to a specified date and time" really should work correctly. Otherwise you have to edit each photo, and you cannot copy and paste into this dialog.
