-----------------------------------
Summary: Document timestamp and timezone behavior for Table API &
SQL
Key: FLINK-8169
URL: https://issues.apache.org/jira/browse/FLINK-8169
Project: Flink
Issue Type: Improvement
Components: Table API & SQL
Reporter: Timo Walther
{{java.sql.Date}}, {{java.sql.Time}}, and {{java.sql.Timestamp}} are timezone
dependent. However, in Flink's Table & SQL API we remove this dependency and
work with UTC timestamps internally. It should be documented how windows use
the timestamps in different timezones for event-time. The behavior for
processing-time should be explained as well. What is the result if I cast both
timestamps to Long, String, or output them to a DataSet/DataStream?
