[jira] [Created] (KAFKA-7911) Add Timezone Support for Windowed Aggregations

Matthias J. Sax created KAFKA-7911:

             Summary: Add Timezone Support for Windowed Aggregations
                 Key: KAFKA-7911
                 URL: https://issues.apache.org/jira/browse/KAFKA-7911
             Project: Kafka
          Issue Type: New Feature
          Components: streams
            Reporter: Matthias J. Sax


Currently, Kafka Streams only support UTC timestamps. The impact is, that `TimeWindows` are based on UTC time only. This is problematic for 24h windows, because windows are build aligned to UTC-days, but not your local time zone.

While it's possible to "shift" timestamps as a workaround, it would be better to allow native timezone support.
