<p>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). <br>
</p>
<p> 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.</p>
<p>I'll take another look at the code and see if I can't come up
with a workaround.</p>
<p>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?<br>

<div>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?<br>
