We have just changed what is stored in the updated_at field; it now
represents the time that the stack had an update operation performed on
it. This means that updated_time will often be None.

Horizon needs to expect a None updated_time, and its probably not
appropriate to even have an Updated column on displayed tables.

Title:
  stack.updated_time is None

Status in Orchestration API (Heat):

Status in OpenStack Dashboard (Horizon):

Bug description:
  I did a DevStack install, around 22:42 on 2 March 2013 UTC.  I used
  horizon to create a stack.  The creation eventually finished
  successfully, but the stack's "updated_time" field always held None.
  I suppose this is pretty bad for lots of reasons.  The one I noticed
  is that it crashes horizon's page for listing stacks.  I captured the
  crash output at http://paste.openstack.org/show/71561/.  Here is an
  excerpt:

  /opt/stack/horizon/openstack_dashboard/wsgi/../../horizon/tables/base.py
  in get_data

                                   self.display_choices

                                   if value.lower() == (data or
  '').lower()]

              if display_value:

                  data = display_value[0]

              else:

                  for filter_func in self.filters:

                      data = filter_func(data)

      ...

              if data and self.truncate:

                  data = truncatechars(data, self.truncate)

              self.table._data_cache[self][datum_id] = data
