Probably Completed, Processed, and Pending I guess. I don't know why you want to log a Pending basket though. It may never get paid depending on what happens.

$date = cbFormatDate( $variables['var2']->time_initiated, 1, false );

function extract_basket_item($item)
{
    return $item->renderColumn();
}
