        }
    ]
}

**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.



stack_name = req_params.get('StackName')
    stack = None
    if stack_name:
        stack = find_stack(stack_name)
        if not stack:
            return stack_not_found_error(stack_name)
    else:
        template_deployer.prepare_template_body(req_params)
        template = template_preparer.parse_template(req_params['TemplateBody'])
        req_params['StackName'] = 'tmp-stack'
        stack = Stack(req_params, template)
    result = stack.describe_details()
    id_summaries = {}
    for resource_id, resource in stack.template_resources.items():
        res_type = resource['Type']
        id_summaries[res_type] = id_summaries.get(res_type) or []
        id_summaries[res_type].append(resource_id)
    result['ResourceTypes'] = list(id_summaries.keys())
    result['ResourceIdentifierSummaries'] = [
        {'ResourceType': key, 'LogicalResourceIds': {'member': values}} for key, values in id_summaries.items()]
    return result
