go - Specifically check for timeout error

Question

I use the following to check for timeouts when calling a webservice, but I would like to check specifically if there is a timeout error returned. How do I do that :S

I have this:

// Timeout
type Timeout struct {
    Connect   time.Duration
    ReadWrite time.Duration
}

// TimeoutDialer
func TimeoutDialer(timeout *Timeout) func(net, addr string) (c net.Conn, err error) {
    return func(netw, addr string) (net.Conn, error) {    
        conn, err := net.DialTimeout(netw, addr, timeout.Connect)
        if err != nil {
            return nil, err
        }
        conn.SetDeadline(time.Now().Add(timeout.ReadWrite))
        return conn, nil
    }
}

// HttpClient
func HttpClient(config Config) *http.Client {
    to := &Timeout{
        Connect:   time.Duration(config.MaxWait) * time.Second,
        ReadWrite: time.Duration(config.MaxWait) * time.Second,
    }

    return &http.Client{
        Transport: &http.Transport{
            Dial: TimeoutDialer(to),
        },
    }
}
