time sync ?  only one needs to tell time :-) ... the rest just need to 
display
the remainder of the digits...

Either use messages over the appletalk of what to display... or treat each
computer 'up' the chain like a dumb mechanical counter....

call the boxes H1, H2, M1, M2, S1, S2.... S2 tells the time... when it 
rolls over to
zero it sends a 'tick' to S1...  S1 knows its 'position', so when it 
rolls over from 5
to 0, it sends a tick to M2.... and up the 'ticking' goes.

Either way would be 'fun' :-)
