> Processing time timers should use outputTimestamp rather than input watermark

> Key: BEAM-14244
> URL: https://issues.apache.org/jira/browse/BEAM-14244
> Project: Beam
> Issue Type: Bug
> Components: runner-core, sdk-java-core
> Reporter: Steve Niemitz
> Assignee: Steve Niemitz
> Priority: P1
>
> Currently processing time timers ignore the outputTimestamp and instead use
> the input watermark at the time they fire. This is wrong because the input
> watermark can have advanced arbitrarily far past the actual output timestamp
> when it fires.
> The correct behavior should be to instead use the outputTimestamp the timer
> was configured to fire with.
