this is my code, and the result shows always the total number of comments instead of number of comments after 12 february 2020.

I don’t know why it does not working.

    #!/usr/bin/php

    <?php
    if ( ! defined('ABSPATH') ) {
        /** Set up WordPress environment */
        require_once( dirname( __FILE__ ) . '/wp-load.php' );
    }

    $args1 = array(
            'status' => 'approve',
            'date_query' => array(
                array (
                   'after' => '2020-02-12 10:00:00',
                ),
             ),
          );

    $comments = new WP_Comment_Query( $args1 );

    $comms = get_comments( $comments );

    $nbr = count( $comms );


    echo "$nbr"
    ?>

thank you for your help
