php – Run if comment date more (+ 1hour) current time

Example:

Server date and time 04.05.2021 9:00

If comment date and time 04.05.2021 9:58 – NOT run

If comment date and time 04.05.2021 10:02 – RUN

$now = current_time( 'mysql' ); 
    
    $datacomm = strtotime( get_comment_date( 'Y-m-d h:i:s', $comment ));
    $later = strtotime( date( 'Y-m-d H:i:s', strtotime( $now ) + 7200 )); //3600 seconds = 1 hour
    
    
    if( $datacomm > $later ) {
    
    // run this
    
    }
