I use iPhoto to manage my pictures. Unfortunately I have many pictures from the 80s. These pictures are actually slides that I have scanned in during 2008. So my problem is that the creation date of all these pictures is set to the date when I scanned it in. Now I want to set the real date of these pictures. Unfortunately I don't know the exact date, but at least the year.
So is there any function available to only set the year field of a date without a specific date?
