HI,
  
 I run nova-manage service list on n1 which is the contoller node, and the output is below
 nova-conductor   n1                                   internal         enabled    :-)   2013-06-27 07:13:12
nova-cert        n1                                   internal         enabled    :-)   2013-06-27 07:13:12
nova-compute     n1                                   nova             enabled    :-)   2013-06-27 07:13:10
nova-scheduler   n1                                   internal         enabled    :-)   2013-06-27 07:13:12
nova-consoleauth n1                                   internal         enabled    :-)   2013-06-27 07:13:11
nova-compute     n2                                   xzone            enabled    :-)   2013-06-27 07:13:17
nova-compute     n3                                   nova             enabled    :-)   2013-06-27 07:13:17

 however, the n1's time is
 date
 Thu Jun 27 15:13:25 CST 2013
  
 why the time got from date is different from that from nova-manage?
  
 BTW, the mysql time zone related setting is
 system_time_zone                                  | CST
 time_zone                                         | SYSTEM   
  
 Thanks.
