I scanned quite some old (before 1970) film negatives.
The scann tools add the date of scanning as exif-meta data to the file.

As a result picture catalog apps sort these pictures according to their stored meta dates (kMDItemContentCreationDate).

In a naive approach I used "touch" or "SetFile" with the "real" date when the original picture was taken (e.g. 01.01.1967)

Both commands create weird results with dates far into future or do nothing.

Any solution to solve my problem?
