All the nodes report the same grandmasterIdentity.  I guess that one
of your BCs is introducing the currentUtcOffsetValid flag, as Jake
said.  You can sniff the announce messages between BC1 and BC2 to find
out who is at fault.

Maybe the BCs are also NTP cleints and therefore feel that they know
the correct offset?

Thanks,
