Problem:
How to modify the format of the date shown on a backend post listing page?

Solution:
Toolset does not influence that.

Here is one generic solution from a Stack Overflow answer:

add_filter( 'post_date_column_time' , 'my_post_date_column_time' , 10 , 2 );
function my_post_date_column_time( $h_time, $post ) {
    $h_time = get_post_time( 'd/m/Y', false, $post );
    return $h_time;
}
