**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 = find_stack(stack_name)
    deployer = template_deployer.TemplateDeployer(stack)
    deployer.delete_stack()
    return {}
def update_stack(req_params):
    stack_name = req_params.get('StackName')
    stack = find_stack(stack_name)
    if not stack:
        return error_response('Unable to update non-existing stack "%s"' % stack_name,
            code=404, code_string='ValidationError')
    template_preparer.prepare_template_body(req_params)
    template = template_preparer.parse_template(req_params['TemplateBody'])
    new_stack = Stack(req_params, template)
    deployer = template_deployer.TemplateDeployer(stack)
    try:
        deployer.update_stack(new_stack)
    except Exception as e:
        stack.set_stack_status('UPDATE_FAILED')
        msg = 'Unable to update stack "%s": %s' % (stack_name, e)
        LOG.debug('%s %s' % (msg, traceback.format_exc()))
        return error_response(msg, code=400, code_string='ValidationError')
    result = {'StackId': stack.stack_id}
    return result
