I don't understand what you are trying to do here.
Is this call to 'set_enginetime' in the agent, or in the manager?
You shouldn't need to touch the engine boot information in the agent.
The boot count and time values are handled automatically by the
Net-SNMP library.
They will be updated when the agent re-started, and maintained as the
agent runs.
You shouldn't need to meddle with them.
I'm also not entirely sure why you are trying to re-implement an agent
in the first place?
Why not simply use the standard Net-SNMP agent - which we know works!

Yes - that should be what happens.
It's probably worth checking this - try running the agent with packet
dumps turned on
(either '-d' or '-Ddump'), and compare the values in the (first) Report packet
with those in the (second) Request packet

And which one is right?
What are the two values, and how do they compare with the value in the
Report message
(and with the engineBoot value from before the agent was restarted) ?

No - it's maintained by the library code, and updated automatically
when the agent restarts. You shouldn't need to change it directly.
I'm actually wondering whether the manager software is updating
the boot count value correctly - or whether it's using the same value
for both requests?
