The "Posted Time" should be the time of publish
Review Request #3753 — Created Jan. 18, 2013 and submitted
Currently, the time_added of a review request is setup when a new record is added. If there is a time difference between the creation time and the time of actually publishing the review request, the field is not updated and it shows the time of creation as the "Posted" time. This is fixed by updating the "time_added" field to current time when a review request is published.
