Scala + Play, how to get a duration from the HOCON configuration?

Question

Imagine I have a Duration value defined in my application.conf file. The documentation says it can parse Durations, but I can't see how.

timeout = 60 milliseconds

Can I parse it directly as a duration value? Ideally I would like to do something like this

val timeout = current.configuration.getMilliseconds("timeout")
(myActor ? GiveMeSomething)(timeout).mapTo[...]

but timeout is an Option[Long]. Thanks for any tips.

Play's configuration does support Duration, FiniteDuration and other Scala types. Use: configuration.get[FiniteDuration]("path.to.duration") The Configuration.get function takes an implicit ConfigLoader[A]. Play comes with a lot of implementations and easy to add additional ones.
