Idiomatic way to timeout websocket.Dial in go?

I have code like the following:

_, err := websocket.Dial("wss://remote-server", "", "http://localhost")

if (err == nil) {
  fmt.Println("Worked!")
} else {
  fmt.Println("Fail")
}

When remote-server is down, it takes 60s to timeout. I found websocket.SetDeadline (http://godoc.org/code.google.com/p/go.net/websocket#Conn.SetDeadline), but I don't have a connection yet to apply it to. I can pass a Config to DialConfig, but I can't see where to specify a timeout doing that.

I found https://code.google.com/p/go-wiki/wiki/Timeouts, is this how I have to do it? How do I correctly pass the error code back from the goroutine?

I havent used the go websocket package yet but from what I can infer from the documentation one should probably use net.DialTimeout(...) coupled with websocket.NewClient(...)

The source of DialConfig uses the same method but limited to net.Dial.
