See step 1, bullet 3 in the docs for setting up a compute node:

compute.html

"Synchronize from the controller node. Follow the instructions in the
section called “Network Time Protocol (NTP)”."

Title:
  Weak service state probe algorithm

Status in OpenStack Compute (Nova):
  Opinion

Bug description:
  I've faced with problem when service state of compute node got from
  nova-manage service list command was XXX most time and some times it
  was ok, despite in fact compute was ok all time. I found that it
  coused by time shift between controller and compute node. I think that
  is the bug to treat node as down basing only on update time, because
  if we try to ping, probe tcp port or any other real ways to conversate
  with node we will found it ok.
