en tout cas, all the network refers to one time, and only
one at a time. that's the point i'm trying to make. if it
doesn't come over when i put it like this i should take a
few weeks off and brush up on my english.

the thing is
that you need to keep time well-defined
and controllable at one point, for the whole network.
if you don't, things like synchronization and transport
control are tough to get right.
yet earlier, you wrote:
yes, because you are confusing things yourself.
there is
only one time within one system. if you sync this system
to external, the flow of this time sways somewhat, but
it's still one integral time.
so, there isn't just one time! this is the whole issue with positional
versus rate synchronization. positional references provide one kind of
time ("transport" or "virtual" time). its not monotonic, not
invariant
and not continous. rate synchronization controls a continuous, but not
necessarily monotonic or invariant flow of time.
