liwei li commented on FLINK-20443:
----------------------------------
this is happening in our environment when using the continuous processing time
trigger. When I searched on JIRA, I found this issuse, but it hasn't been
updated for a long time, so I resubmitted a PR, including the trigger window
and some test code. Can give me this ticket and help revicew code?
thx.

> 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.
