[jira] [Comment Edited] (FLINK-27774) Window Agg doesn't work when used in Batch Table API
[ https://issues.apache.org/jira/browse/FLINK-27774?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17555372#comment-17555372 ]

I looked at it and from the documentation [https://nightlies.apache.org/flink/flink-docs-release-1.15/docs/dev/table/concepts/time_attributes/] I see that
"During the conversion, Flink always derives rowtime attribute as TIMESTAMP WITHOUT TIME ZONE, because DataStream doesn’t have time zone notion, and treats all event time values as in UTC."
I don't see it explicitly defined as LocalDateTime. Can you point me to the documentation? I can make the change if that's the case.
