>             Project: Flink
>          Issue Type: New Feature

> For supporting different timezones, it might be necessary to offset windows 
> by some hours (e.g., -8). The DataStream API allows to define 
> [offsets|https://ci.apache.org/projects/flink/flink-docs-release-1.3/dev/windows.html#tumbling-windows].
>  Flink SQLs group windows should also support such a behavior. It might be 
> necessary to introduce the semantics to Apache Calcite first before we can 
> implement it in Flink.
