  return $columns; 
}

add_action(\'manage_post_posts_columns\',\'manage_columns_for_post\');

// populate custom columns for `post` post type
function populate_post_custom_columns($column,$post_id){

  //local date column
  if($column == \'local_date\'){
    // convert date to local by $post_id
    echo \'Published <br> 2020/12/12 at 6:30 am\'; // dynamically get date of each post and display it 
  }
