There is a minimum granularity for the timeout.  Keep in mind that 
this involves IPC to another process, which may have to be launched, 
then become active, and display the dialog to the user, who will then 
have to respond to it.  You should be thinking in terms of minutes 
rather than seconds.  If you need finer control, you can use one of 
the asynchronous calls and cancel the notification yourself.
