Update timestamp on an image when APPROVING UPLOADS

[RFANostalgia]

I recently updated a friends Gallery to 1.6 from 1.5.  The way he uses the gallery is such that all image uploads require 'APPROVAL'.
He tells me that 1.5 used to have an 'Update Timestamp' option when approving, such that he could set the uploaded date to 'today' even though the image was placed in the Approval Queue' some days ago.    Apparently this checkbox no longer exists.

Question: did it ever exist ?   If so where was it and where if anywhere is it now ?

Thanks.
