I'll take a look. Thanks!

> Right now Streams API unversally represents time as ms-since-unix-epoch.
> There's nothing wrong, per se, with this, but Duration is more ergonomic for 
> an API.
> What we don't want is to present a heterogeneous API, so we need to make sure 
> the whole Streams API is in terms of Duration.
>  
> Implementation note: Durations potentially worsen memory pressure and gc 
> performance, so internally, we will still use longMs as the representation.
