I don't think we need to create a builder here anymore. These tests don't currently set the time zone in the builder anyway so aggregationBuilder.timeZone() will always be null which implicitly means the time zone will be treated as UTC. As mentioned before we should add a test that does set the time zone to test its treated correctly but that doesn't need to be part of this PR so I think we can remove this line and just pass in null below?

roundingInfos = AutoDateHistogramAggregationBuilder.buildRoundings(aggregationBuilder.timeZone());

int nbBuckets = randomNumberOfBuckets();
int targetBuckets = randomIntBetween(1, nbBuckets * 2 + 1);
List<InternalAutoDateHistogram.Bucket> buckets = new ArrayList<>(nbBuckets);
