> Timezone not passed as part of granularity when passing
> TimeExtractionFunction to Druid
> ---------------------------------------------------------------------------------------

> Key: CALCITE-2107
> URL: https://issues.apache.org/jira/browse/CALCITE-2107
> Project: Calcite
> Issue Type: Bug
> Components: druid
> Reporter: Nishant Bangarwa
> Assignee: Nishant Bangarwa
> Priority: Major
>
> When sending granularity to TimeFormatExtractionFunction we need to add
> timezone to the granularity to align it with the timezone specified in
> calcite connection. If no timezone is specified in granularity, It is
> considered as UTC timezone by druid.
> Note the return value in is as per granularity UTC and not IST as expected -
> {code}
> @Test
> public void testTmeWithFilterOnFloorOnTimeWithTimezoneConversion() {
> final String sql = "Select cast(floor(\"timestamp\" to MONTH) as
> timestamp) as t from "
> + "\"foodmart\" where floor(\"timestamp\" to MONTH) >= '1997-04-30
> 18:30:00 UTC' order by t"
> + " limit 1";
> final String druidQueryPart1 =
> "filter\":{\"type\":\"bound\",\"dimension\":\"__time\","
> + "\"lower\":\"1997-05-01T00:00:00.000Z\",\"lowerStrict\":false,"

> "\"ordering\":\"lexicographic\",\"extractionFn\":{\"type\":\"timeFormat\","

> final String druidQueryPart2 =
> "\"granularity\":\"month\",\"timeZone\":\"IST\","
