php - Wordpress - Format a post meta (date) -

i want display date of event on revolution slider. managed display date using meta slug, don't format.

i have no idea start ! thought of, maybe creating post meta desired date format, update when first date meta updated, seems bit overkill ?

i have code add meta , update desired format : but there better way ?

function kia_convert_content(){     $events = get_posts(array('numberposts'=>-1,'post_type'=>'pec_events'));      foreach( $events $post ) : setup_postdata($post);       // old meta     $mauvais_format = get_post_meta($post->id,'pec_date', true);       // format date     date_format($mauvais_format, 'j f y');      //add or update new meta     if(metadata_exists('post', $post_id, 'l2v_pec_date')){         update_post_meta($post->id,'new_pec_date',$bon_format);     }else{         add_post_meta($post->id, 'new_pec_date', $bon_format, true)     }      endforeach;  }
