I'm trying to fire an event when the Attack button is held down for 4 seconds.
How can I do this?

client_PreThink(id)
{
    if(!is_user_alive(id))
        return PLUGIN_HANDLED
    
    if(pev(id,pev_button) & IN_ATTACK))
    {
              RunEvent(); // I want this called 4 seconds after holding the attack button.
    }
}
