> 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.
