Is anyone else having problems with Apertures Date fields?

Question

After experiencing a sysems failure I began restoring my images from backups.  I have had no end of problems with Image dates.  I have come to the determination that Aperture is NOT using either the "Create Date" or "DateTimeOriginal" as the image "Date" or "Date Created" data if other fields have other dates.
Here is a clip from my image metadata using exiftool:
File Modification Date/Time     : 2012:09:23 19:53:15-04:00
File Access Date/Time           : 2013:01:16 11:34:38-05:00
File Inode Change Date/Time     : 2013:01:16 11:31:32-05:00
Create Date                          : 2006:02:20 11:51:12.10
Date/Time Original              : 2006:02:20 16:51:12.10
Modify Date                          : 2006:02:20 11:51:12.10
And here is what Aperture utilized on import
Date:                               9/23/12 7:53:15 PM EDT
Date Created                         9/23/2012 7:53:15 PM
So Aperture utlized the File Modification Date/Time as the Create Date despite that the fact that the Create Date field is present and is properly formatted in the original image.
According to the Aperture mapping table, this shouldn't be happening.
Now, before someone recommends that I use Aperture's Date Adjust utility - I'm talking about  slightly over 30,000 images.  Editing images one at a time, or in blocks when you don't know what field Aperture is using as the Create Date would require individual inspection of each image followed by manual adjustment of each image.  That approach isn't acceptable.

Answer 1

Hmm ok, let me restate the issue then, I thought I was clear.  I could have pointed out in my original post however, that only the EXIF and IPTC date fields were displayed from the metadata dump.
The data set presented in my first post is the EXIF dataset from the file which clearly shows the image was captured by digital camera at
Create Date                          : 2006:02:20 11:51:12.10
Date/Time Original              : 2006:02:20 16:51:12.10
(The delta of 5 hours is the result of Zulu versus local time offset)
But, when I ingested it into Aperture, the import routine utilized the IPTC field
File Modification Date/Time     : 2012:09:23 19:53:15-04:00
which is updated by the OS whenever you move the file around outside of Aperture. (a number of image data fields are updated by the OS - filename for example is another.).  This resulted in the image date fields being stamped in Aperture as:
Date:                               9/23/12 7:53:15 PM EDT
Date Created                         9/23/2012 7:53:15 PM
Which obviously came form the File Modification Date/Time field and not (either) the Create Date or Date/Time Original fields.
