[Bug 1579631] [NEW] Node time changed，resulting in abnormal state of neutron agent.
Public bug reported:
Bug performance
1）compute node without L3 agent and DHCP agent，But in the control node can see the compute node’s L3 agent and DHCP agent work normally

Bug reason
2）After check，the agent is down,so heartbeat_timestamp is not updated.
However,for some reason,the controller node's current time changed(Earlier than heartbeat_timestamp) ,The controller node 's current time minus the agent' s heartbeat_timestamp negative,So the controlerr node executing “ neutron agent-list” command, we can see the aegnt status is :-)
