Aperture EXIF shows incorrect time zone

I'm having an issue with photos from multiple cameras.

I bring them into Aperture and format the file name as date-hours-min-sec.

The titles all work out fine, but when I look at the EXIF information, the time zone in the "Date" field (when I select 'EXIF Info' and then look at the 'Date' field from the 'Info' tab) is always PDT (my home time zone).

The EXIF time is actually correct in the local time zone (which is say in Africa, for example UTC+2 (CAT) instead of PDT), but Aperture continues to show PDT. So for example it will show 9PM, but it is 9PM in CAT, not 9PM in PDT.

If there something simple I am doing incorrect here?

When moving between time zones, I take all my cameras and adjust the time zone to the correct local time zone. So I would think every file "knows" that it is in the proper time zone, and I assume this would carry over when importing into Aperture. But I guess not?

Any tips would be great! Thanks!
