The same happens with a SQL query
> Integrate time indicators for Table API & SQL
> ---------------------------------------------
>
> Key: FLINK-5884
> URL: https://issues.apache.org/jira/browse/FLINK-5884
> Project: Flink
> Issue Type: New Feature
> Components: Table API & SQL
> Reporter: Timo Walther
> Assignee: Timo Walther
> Priority: Blocker
> Fix For: 1.3.0
>
>
> We already discussed the need for a proper integration of time indicators
> (event-time or processing-time) for both the Table API & SQL on the ML:
> http://apache-flink-mailing-list-archive.1008284.n3.nabble.com/DISCUSS-Table-API-SQL-indicators-for-event-and-processing-time-tp15927.html
> This issue will track the progress. I will work on a design document how we
> can solve this issue.
