xueyumusic opened a new pull request #7695: Add TIMESTAMPDIFF sql support
URL: https://github.com/apache/incubator-druid/pull/7695
Current sql support TIMESTAMPADD, it would be nice if sql could support TIMESTAMPDIFF which is a common used time function and supported by Calcite. It returns the (signed) number of unit between timepoint1 and timepoint2. The grammar is `TIMESTAMPDIFF(unit, timestamp1, timestamp2)`. Unit can be SECOND, MINUTE, HOUR, DAY, WEEK, MONTH, QUARTER, or YEAR.
