To avoid any appearance of conflict of interest, I let this through 
the moderation filter. Now, while I'm technical director for 
certzone, I haven't had anything to do with setting up the e-commerce 
part. You may have discovered an outright bug, and customer service, 
I'm sure, could help.  I can't speak for the financial people either, 
but if you ask, they'll probably refund the prorated time -- about 9 
1/2 hours of a one year subscription.

But there is a lesson here relevant to router operations. As I say, I 
don't know the details of the e-commerce server that handles 
membership.  As a consequence, I don't know exactly how its clock is 
set. While the certzone servers are physically in US Eastern time, 
they might be set to Zulu time. Look at any email message; the time 
is usually Zulu with an offset.

When debugging router interactions, just being on the same time zone 
is something to check, and then, depending on how tight the 
interactions are, you may very well want to turn on NTP 
synchronization.  Otherwise, you won't be sure about whether the 
chicken or the egg crossed the road first, or something like that.

In the ongoing IETF BMWG work on routing convergence, we are hoping 
that NTP will be good enough to track protocol behavior, but some of 
the more statistically-minded researchers are worried that it will 
not. I'm hoping that most of our basic measurements can be done using 
NTP-synchronized routers as the source and sink of data, but other 
workers are pressing for GPS or other, more accurate time 
synchronization.

But really...isn't the term ripoff a little strong? Or, should I say,

             no router rip

:-)

Happy new year.
