comment_date and comment_date_gmt get set in the wp_new_comment()
function. You can't override them before the comment gets inserted
into the database, but you can change them after the fact.

You would need to hook a function to wp_insert_comment and get the ID
of the comment. Then you could call wp_update_comment with your
changes to the dates and the ID and it would update the comment.
