Track response time of simple Action

Global.scala

import play.api._
import play.api.mvc._

object Global extends GlobalSettings {

	def ResponseTime[A](action: Action[A]): Action[A] = Action(action.parser) { request =>
		val start = System.currentTimeMillis
		val result = action(request)
		println( request + " -> " + (System.currentTimeMillis - start) + " ms.")
		result
	}

	override def onRouteRequest(request: RequestHeader): Option[Handler] = {
		super.onRouteRequest(request).map {
			case action: Action[_] => ResponseTime(action)
			case other => other
		}
	}

}

Will this work with Async Actions?
