He has that because Dr Mills has just told him he needs it.

I don't think he meant that.  I think he meant that it should settle on 
a common time regardless of how far off the individual clocks were hen 
the system started.  (I'm not sure what happens if you introduce a new 
machine.  The existing orphans do need to use intersection rules here, 
even though starting orphans mustn't.)

I think the machines are dual homed, for redundancy.
