Working WP Cron on particular native time

The state of affairs is to run insert_post perform each midnight (00:00) of native time. Should run each day on weekday.

perform add_daily_task(){
    if((date('l', time()) != 'Saturday') || (date('l', time()) != 'Sunday')){ 
        // insert put up
    }
}

if(!wp_next_scheduled( 'add_daily_task_schedule')){
    wp_schedule_event(time(), 'each day', 'add_daily_task_schedule');
    // how ought to change time() to fulfill my native schedule?
}

add_action('add_daily_task_schedule', 'add_daily_task');
