The client-side command doesn't have any say in that. On the server 
side, it depends. There is an image property "os_shutdown_timeout" which 
can override the server-side configured graceful shutdown timeout - 
which defaults to 60 seconds. So if you want to control that timeout in 
your images you can use the image property. See [1] for details.
