"Do not import duplicates" IS importing duplicates

I just stumbled upon this Aperture bug after switching the time zone on my macbook pro on a flight back home from vacation. As with Shaun, switching the time zone back to the previous time zone allowed Aperture to detect duplicated again. As someone who travels a lot, I'd love to see this issue addressed in the next update.

Apple are aware of the issue, as I filed a bugreport that was marked as a duplicate. I have not other info.

I am seeing the same behavior, I just did a transatlantic cruise, and after changing timezones as we proceeded westward, the issue showed up. I hope it gets fixed in the next update. Now if I can just figure out how to get my .mov files to import as they have before the 3.2.1 update, I will be a happy user again.
