}

**LastUpdatedTimestamp** is not returned.

## Expected behavior

Trying to use Localstack with some dependencies which expects the field LastUpdatedTimestamp. I saw in few older posts the field was being returned.

    cs_name = req_params.get('ChangeSetName')
    change_set = find_change_set(cs_name, stack_name=stack_name)
    if not change_set:
        return error_response('Unable to find change set "%s" for stack "%s"' % (cs_name, stack_name))
    LOG.debug('Executing change set "%s" for stack "%s" with %s resources ...' % (
        cs_name, stack_name, len(change_set.template_resources)))
    deployer = template_deployer.TemplateDeployer(change_set.stack)
    deployer.apply_change_set(change_set)
    change_set.stack.metadata['ChangeSetId'] = change_set.change_set_id
    return {}
