In a lot of old Akka examples you will see the following statements:

import akka.util.Timeout
import akka.util.duration._
implicit val askTimeout = Timeout(1 second)

This will give error ‘object duration is not a member of package akka.util’. It turns out duration is now included in Scala standard library. To fix the error use the following import statement:

import scala.concurrent.duration._
