following are code analysis, only FYI
not sure fully understand the question, but I think
servicegroup/drivers/db.py might be a good place to look at
a timer function _report_state is called periodically ,when its updated,
the field will be updated
class TimestampMixin(object):
created_at = Column(DateTime, default=lambda: timeutils.utcnow())
updated_at = Column(DateTime, onupdate=lambda: timeutils.utcnow())

Subject: [openstack-dev] [nova] How does Nova update time for compute
nodes?
Hi, Nova guys
I know that 'nova-manage service list' will output 'XXX' for compute nodes
is the time between api node and compute node are larger than
service_down_time. At the same time Nova update db cyclically. So my
question is how does Nova update that data? via crontab or something else?
