Cron/Plugin error

I am currently making a cron that is supposed to run once a day and adds a 1 to the post meta. I have tested the function to run on a page load and it does this correctly. However, when I tie it to a cron event, every time the page loads it adds 4 to the total. I do not understand why this is happening. I called my hosting site and they say it should only be running once a day. Here is the code:

/*Adds a day to paused days meta.*/

$time = rand(1000, 1200);

if ( ! wp_next_scheduled( 'update_pused' ) ) {
  wp_schedule_event( time()+$time, 'daily', 'update_paused' );
}

add_action( 'update_paused', 'add_day_to_paused' );

function add_day_to_paused() {
	global $woocommerce;
    $args = array(
		'post_type'			=> 'shop_order',
		'post_status' 		=> 'publish',
                'posts_per_page' => -1,
		'tax_query' => array(
                    array(
                        'taxonomy' => 'shop_order_status',
                        'field' => 'slug',
                        'terms' => array('paused')
                    )
                )
	);
	$loop = new WP_Query( $args );

	while ( $loop->have_posts() ) : $loop->the_post();

		$order_id = $loop->post->ID;

  		$order = new WC_Order($order_id);

  			$getdays = get_post_meta($order_id,'paused_days', true);
        	$totaldays = 1 + $getdays;
        	update_post_meta($order_id,'paused_days',$totaldays);

  endwhile;

}
