---------------------------------------

Is there any reason not to do the automatic conversion ? This is mildly confusing

> Both the website and the JavaDoc promotes ".window(TumblingEventTimeWindows.of(Time.days(1), Time.hours(-8))) For example, in China you would have to specify an offset of Time.hours(-8)". But both the sliding and tumbling event time assigners do not allow offset to be negative.
