> 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.
