Though it's not explicitly documented, I'm guessing that this is the expected behavior. The date refers to when the asset was created and when you're modifying the image, you're probably implicitly creating a new asset. Nothing in the ALAsset documentation suggests that its properties correspond to the image's EXIF data.

To access the EXIF data, you could use the Image I/O framework (available since iOS 4.0), specifically the CGImageSourceCopyProperties function.
