This bug is reproducible.
Again I am referring to the 13 images I imported using the admin control panel "Check New Images".
From the 4images_images table, image_date = 1022222283
From 4images/details.php, the date displayed is: 05.24.2002 01:38
From Admin CP, "Edit Images", date displayed is: 2002-05-24 06:38:03
From ls -l at a Linux prompt, the file date is: May 24 01:28
I don't think the date displayed in the Admin>Edit Images is correct.
