I already thought of that one, but thanks anyway for the question.

There was no accounting entry from the first job, but that's not really
a surprise because accounting entries are either buffered before been
written to disk or there is a delay in updating the EOF marker.

You can test this for yourself.

In one session, log into a VMS box and have "$ acc/since={10 minutes ago}"
ready to run.

Now log in (and out again immediately) to a VMS box from another session
then run the $ acc command above immediately. You will see there is a
delay before the accounting entry from that session becomes visible.

This is on VMS Alpha v8.3, in case this behaviour is different in other
VMS versions.

BTW, still no reply from HP yet...

Simon.
