I would think that the file's timestamp is derived from the time set in 
the camera, one way or another.  Either the camera creates the file on a 
standard (probably win32) filesystem when the picture is taken, or the 
timestamp is assigned from the metadata by some special software that 
fetches images to your computer from the camera.

Sounds like some sort of bug to me, perhaps where some piece of software 
neglects to take DST into account.
