Comment(by MMN-o):

 Great that someone woke this ticket to life. I had no means whatsoever
 when I posted it to delve into the issue, but I'll give it a shot now if
 miqrogroove doesn't make it first :)

 It seems DateTimeDigitized tells us when an image was digitized, as
 opposed to DateTimeOriginal which tells us when it was originally
 _created_. That is, an analog picture which was scanned should have
 different DateTimeOriginal and DateTimeDigitized, whereas a digital still
 image reasonably has identical timestamps.

 The priority list for Wordpress to interpret EXIF timestamp should be:

 1. DateTimeOriginal (This is when the image was first created. Should
 override everything.)
 2. DateTime (I'm guessing this is most common, and more likely to
 represent correct time than digitization)
 3. DateTimeDigitized (if no other data is available, assume digitization
 equals time of creation)
