How do I save "DateTime imported" value in Digikam?

[Jens Benecke]

Hi,

I have roughly 48’000 photos which I am converting from iPhoto. (see github -> jensb/iphoto2xmp)

iPhoto saves a timestamp called „Datetime Imported“ in addition to „Date taken“ and „Date last modified“.
It’s not the „DateTimeDigitized“ flag known from EXIF, this is the date the photo was imported into iPhoto.

I would like to preserve this flag during my Digikam conversion.
What XMP flag would be most suitable for this purpose?

Thanks!
