> We need to make sure that filters on timestamp are passed to Druid with
> correct timezone.
> After CALCITE-1617, Calcite will generate a Druid query with intervals
> without timezone specification. In Druid, these intervals will be assumed to
> be in UTC (if Druid is running in UTC, which is currently the
> recommendation). However, in Hive, those intervals should be assumed to be in
> the user timezone. Thus, we should respect Hive semantics and include the
> user timezone in the intervals passed to Druid.
