Public bug reported:

In my environment, the neutron-server (on the controller) and the
neutron agent (OVS agent - on the compute host) had a timestamp offset.

The date command shows the following:

Mon Mar 16 02:50:36 UTC 2015  --> On the compute.
Mon Mar 16 09:28:52 UTC 2015 --> On the controller.

The neutron agent in the openvswitch-agent.log says connected to AMQP server on <IP>:5672
However, the neutron server doesn't seem to register the agent.

Upon switching on debug - the server.log on the neutron-server shows:

 Message with invalid timestamp received report_state /usr/lib/python2.7
/site-packages/neutron/db/agents_db.py:232

There's no way to detect this problem from the compute node - since it
gives an illusion that the service is connected to AMQP - however, only
when debugged on the neutron-server, the actual error is determined.

In agents_db.py, report_state should throw back an exception to the
agent - saying the reporting state failed with the appropriate message.
This can be achieved by  bubbling an exception from the report_state
method on a timestamp miss match to the OVS agent.
