aws cloudformation list-stack-resources --stack-name "mystack" 
{
    "StackResourceSummaries": [
        {
            "LogicalResourceId": "MyS3Bucket",

            "ResourceType": "AWS::S3::Bucket",
            "ResourceStatus": "CREATE_COMPLETE"
        }
    ]
}

**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')
    stacks = [s.describe_details() for s in state.stacks.values() if stack_name in [None, s.stack_name, s.stack_id]]
    if stack_name and not stacks:
        return error_response('Stack with id %s does not exist' % stack_name,
            code=400, code_string='ValidationError')
    result = {'Stacks': {'member': stacks}}
    return result
