I think Harry's got this right.=20

While we're on the topic of prtAlertTime, I had a question come to me =
about this object. As I had mentioned when we were changing this object =
to mandatory, the sysUpTime is kept in our Network Interface Card (the =
issue at the time was due to problems getting the time from the NIC, but =
I don't care to revisit that aspect). What's the printer to do when it =
has two such cards installed? One might argue that there's one power =
supply so the times start when the power is turned on, but the time =
could also be kept in an external NIC that communicates with the printer =
over the parallel port. Also, I'm not sure, but the clock drift between =
two NIC timers could be significant.

Any thoughts?

I would expect Jay or Dave to chime in here because I think they are the =
ones
who finally realized the great benefit to knowing something about the =
time
related to events. My recollection is that we simply realized timing of =
events
is essential information and should not be considered optional. The time =
is in
TICKS or something related to sysUpTime, so there's no extra burden in =
terms of
time keeping or having to put a Timex (or Rolex) in the machine.

Subject: PMP> Justification for prtAlertTime and prtAlertTimeGroup ch

I am finally getting around to gathering up the justifications
for the changes between RFC1759 and the new Printer MIB. I have
been able to collect the justification for all changes except
for one. The change that I can not find any justification for
is the move of prtAlertTime from the prtAlertTimeGroup to the
prtAlertTableGroup and the subsequent deprecation of the
prtAlertTimeGroup. I have searched both the PMP and PWG mail
archives and while I can find mail that discusses the change,
I can not find any mail that says why the change was made or
why the change was required.
Help?
