It seems to be unclear for them, that the time unit of timestamps and watermarks is milliseconds.
> They just see TimeWindow.seconds(...) or something similar and assume the timestamps
to be of the same unit (seconds) which is obviously not the case.
> I just checked the documentation and there is no explicit specification of the time unit
used for timestamps.
> After short talk with [~aljoscha], I'll open a mini-PR to address this issue.
