@andrewg: You can achieve this by combining window with something else, e.g.:

yourObservalble
                .window(1, TimeUnit.SECONDS)
                .flatMap { it.firstElement().toObservable() }

But I wonder why do you need the first element at the end of time window? throttleFirst seems like a useful thing.
Also, if you don't need it to be exactly at the end of time window, you could use a workaround like this:

yourObservable
                .throttleFirst(1, TimeUnit.SECONDS)
                .delay(500, TimeUnit.MILLISECONDS)

This will give you first element "on average" at the end of time window.
