How to get the time it took to connect on a request basis using Jetty Client

I want to compute per request the time between the begining of request and time connection is established (TCP connection establishment).

I asked this question question but it was ambiguous.

I had a look at proposed answer, maybe I misunderstood, but I understand that Connection.Listener works on a global basis at least (Overall connect time)

So I tried the approach based on SocketAddressResolver:

    private static class CustomSocketAddressResolver implements SocketAddressResolver {
        private StopWatch stopWatch = new StopWatch();
        
        private SocketAddressResolver adaptee;
        
        public CustomSocketAddressResolver(SocketAddressResolver adaptee) {
            this.adaptee = adaptee;
        }
        
        public long getConnectTime() {
            return stopWatch.getTime();
        }


        @Override
        public void resolve(String host, int port, Promise<List<InetSocketAddress>> promise) {
            stopWatch.reset();
            stopWatch.start();          
            adaptee.resolve(host, port, new Promise<List<InetSocketAddress>>() {

                @Override
                public void succeeded(List<InetSocketAddress> result) {
                    // Add as first address an invalid address so that we test
                    // that the connect operation iterates over the addresses.
                    stopWatch.stop();
                    promise.succeeded(result);
                }

                @Override
                public void failed(Throwable x) {
                    stopWatch.stop();
                    promise.failed(x);
                }
            });
        }
    }

Then I can get connect time like this:

 ((CustomSocketAddressResolver) httpClient.getSocketAddressResolver()).getConnectTime()

It works but is there a better way ?
