Yes, it has happened to me. It was a year or two ago so not the current OS or AP version. I seem to remember it was a problem with TIFF files, not JPEGS. I think a couple of other people had seen this, you may to search these forums to find anything. I can't find details after a quick look.
I'm sorry there is no answer. I stopped adjusting the date using Aperture. I now use PhotoMechanic which is reliable for any metadata work you need to do.

David, Thank you for sharing your experience
I'm quite shock the Aperture team ignored such obviously and seriously bug since very earlier version.
However, I’ll adjust the picture date & time by the software you suggestion.
