Hi,

import scala.async.Async.{async, await}


  val fiveSeccond = async {
    val start = new java.util.Date()
    
    await { future { Thread.sleep(5000) } }
    
    val t = new java.util.Date()
    s"> ${start.getSeconds} - ${t.getSeconds}"
  }                                               //> fiveSeccond  :  = scala.concurrent.impl.Promise$DefaultPromise@1cb237
                                                  //| 8
  Await.result(fiveSeccond, 10 second)            //> res1:  = > 16 - 21
