code: @Deprecated
    public PersistentEntityRef<Command> withAskTimeout(FiniteDuration timeout) {
      return new PersistentEntityRef<>(entityId, region, timeout);
    }
docs: The timeout for {@link #ask(Object)}. The timeout is by default defined in configuration
  but it can be adjusted for a specific <code>PersistentEntityRef</code> using this method.
  Note that this returns a new <code>PersistentEntityRef</code> instance with the given timeout
  (<code>PersistentEntityRef</code> is immutable).
  
  @deprecated As of Lagom 1.5. Use {@link #withAskTimeout(Duration)} instead.
