Created attachment 5489 Screenshot of Thunar context menu's EXIF Info and Bulk-Rename's output Thunar 1.6.3 on Xubuntu 13.10 Bulk-Renamer reads out (and sets) the wrong EXIF Taken Time of Images. Example: Photo was taken on 29/08/2010 at 10:00:10 Thunar shows this Information correctly. Renaming this pictures "image.jpg" via Bull-Renamer by "Date / Time" and "Taken Time" "%H%M%S" should rename it to "100010.jpg" but renames it to "102540.jpg"!
Moving to the correct product.
This works correctly here. Maybe this is a problem with your libexif (http://libexif.sourceforge.net/)? Using 0.6.21 here.
No more info, closing.
