the class ESTimeHandler method doCreateAggregation.

@Nonnull
@Override
public Optional<AggregationBuilder> doCreateAggregation(String name, Pivot pivot, Time timeSpec, ESPivot searchTypeHandler, ESGeneratedQueryContext esGeneratedQueryContext, Query query) {
    final DateHistogramInterval dateHistogramInterval = new DateHistogramInterval(timeSpec.interval().toDateInterval(query.effectiveTimeRange(pivot)).toString());
    final Optional<BucketOrder> ordering = orderForPivot(pivot, timeSpec, esGeneratedQueryContext);
    final DateHistogramAggregationBuilder builder = AggregationBuilders.dateHistogram(name).dateHistogramInterval(dateHistogramInterval).field(timeSpec.field()).order(ordering.orElse(BucketOrder.key(true))).format("date_time");
    record(esGeneratedQueryContext, pivot, timeSpec, name, DateHistogramAggregation.class);
