I just looked at your last post in more detail and noticed the IFD0/ExifIFD inconsistency. By the specification, DateTimeOriginal should be written to the ExifIFD, not IFD0. However, it seems that the IFD0 value is correct. To fix this, you could move IFD0:DateTimeOriginal to the properl location:

This will write the proper value to the proper location (ExifIFD in this case), and remove the value from the improper location (IFD0).
