-------------------------------------------------------------
[~mjsax] So... something like the following is needed. Right?
{{kStream}}
{{.windowedBy(TimeZone.getTimeZone("America/Los_Angeles"),
TimeWindows.of(Duration.ofDays(7)).advanceBy(Duration.ofSeconds(1)))}}
or,
{{kStream}}
{{.withTimeZone(TimeZone.getTimeZone("America/Los_Angeles"))}}
{{.windowedBy(TimeWindows.of(Duration.ofDays(7)).advanceBy(Duration.ofSeconds(1)))}}
The first approach is easy to implement, but the second one has a little bit
more clear syntax. Which one would be better?

> 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
> Priority: Minor
> Labels: needs-kip
>
> 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.
