Gee created FLINK-20443:
---------------------------

             Summary: ContinuousProcessingTimeTrigger lost data in last interval in per window
                 Key: FLINK-20443
                 URL: https://issues.apache.org/jira/browse/FLINK-20443
             Project: Flink
          Issue Type: Improvement
          Components: API / DataStream
            Reporter: Gee


 
{code:java}
srcStream
.timeWindowAll(Time.seconds(60))
.trigger(ContinuousProcessingTimeTrigger.of(Time.seconds(10)))...
{code}
 

 This can correctly calculate the following interval result : 0-10s 10-20s 20-30s 30-40s 40-50s

But this lost data which was send in 50-60s.

Because when the first window ends, the time is 59.9999s, it is not equal to window-end-time(60s).So it will not enter the if judgment.
