Daniel Mills commented on BEAM-7642:
------------------------------------
There's at least one example pipeline in the beam repo that relies on this bug:
[https://github.com/apache/beam/blob/master/sdks/python/apache_beam/examples/flink/flink_streaming_impulse.py#L85].
This indicates we may run into problems where fixing this breaks existing
users, unfortunately
> (Dataflow) Python AfterProcessingTime fires before defined time

>
> User on StackOverflow has a problem that AfterProcessingTime on global window
> fires before allocated time (10h). It dumps events within first
> minutes/seconds and then drops the rest due to window closed.
> Code user provided seems valid. I tried to verify time units accepted by the
> method, but I couldn't track it all the way through the code.
