I've no experience with satellites, but is it guaranteed that the
node which provides boot service also provides the system time ?

If the time zone logicals have changed format in 8.4, and if the
system time is being picked up from the upgraded system, then how
do you know the 7.3-2 satellite isn't wrongly interpreting the 8.4
format timezone rules ?

Yes, but are the logicals on the satellite in 8.4 format or 7.3-2 format ?

What does show time say on each of the nodes ?

But that doesn't stop there being a problem due to the current DST
settings; see above.

Note once again that I have no satellite experience however.
