function wpb_last_updated_date( $content ) {

$u_modified_time = get_the_modified_time('U'); 
$custom_content = ''; 
if ($u_modified_time >= $u_time + 86400) { 
$updated_date = get_the_modified_time('F jS, Y');
$updated_time = get_the_modified_time('h:i a'); 
$custom_content .= '
Last updated on '. $updated_date . ' at '. $updated_time .'
';  
} 
 
    $custom_content .= $content;
    return $custom_content;
}
add_filter( 'the_content', 'wpb_last_updated_date' );

Then, set the display style for the last updated time. Below is the style currently used by Naibabiji. Add it to your theme's CSS.

.last-updated {

overflow: hidden;
margin: 10px 0;
padding: 15px 15px 15px 35px;
font-size: 14px;
