FWIW, that's NOT true on OS X. At least when downloading images using  
Image Capture, iPhoto or Aperture, the creation date allocated to the  
file is the time that the file was saved to the memory card.

The time it was downloaded does not appear in the file info in any  
way. The creation date sometimes gets altered as you describe when  
uploaded and downloading, but copying and/or saving doesn't alter it.

I've not tested it to be sure, but suspect that OS X is keeping the  
proper creation date as long as the file is on an HFS volume.
