I love my Olympus digital camera, but it does have one annoying issue. Occasionally, it “forgets” the current time and date. This leaves me with a bunch of images with a corrupt “Date Picture Taken” field (here’s an example). Luckily, Omar’s PhotoLibrary let me hack up a little program to update the date fields in the EXIF header. I couldn’t use JPEG Hammer out-of-the-box becuase it doesn’t handle the corrupt date fields. No matter. My app is a total hack, but since I only need to use it once-in-a-great-while, it’s no big deal.
