Detection/handling notInTimeWindow

I saw this in the archives, related to an issue I am seeing...
http://lists.agentpp.org/pipermail/snmp4j/2008-April/002833.html
Does anyone has a code snippit of this being detected (ideally both from a normal request and a
TreeUtils.getSubtree()) and how it is handled?
For me, between the two, I would be notifying the user of the app about the issue, but need an encompassing
method of both accurately detecting it and handling it...
