If I'm understanding this correctly, it would seem to indicate that
there is no reason for Tops-10 to crash because of a Julian half day
roll over.? I had verified that there is no problem with the internal
time for system logging (I.E., the records that SPEAR gets out of
ERROR.SYS).
Tops-10 and Tops-20 share the same internal time format (a significant
difference between Tops-20 and TENEX), even if Tops-10 doesn't handle it
properly as an unsigned word, it will still handle events up to
27-Sep-2217.? Since that's over 196 years from now, I would assume this
is adequate time to really address the problem.
I'll take another look at the code and see if I can't come up with a
workaround.
Meanwhile, I wanted to make sure I understood what was going on where
with the output below.? Which OPCOM is running where?? Is this only
OPCOM output from APOLLO as HERMES comes up and sends a circuit up
message?? The START /NETWORK DECNET is issued on HERMES?

That doesn't fully answer the question. ?What
you see is the system
log, which presumably uses VMS time stamps. ?Those have a wide range.
?The question is what the DECnet events would show, when encoded in
the NICE protocol. ?If you configure it to send events (like node
reachable or circuit up) to another node, what do the timestamps look
like on that other node?
