The timezone in ES is UTC, how to set it to local time?

Here is my code:

with Elasticsearch(hosts=hosts, timeout=300) as es:
    if not es.indices.exists(index=index_name):
        es.indices.create(index=index_name)

    doc = {
        "timestamp": timestamp,
        "hostname": hostname,
        "dbname": dbname,
        "result": result
    }

    doc_id = "{}-{}-{}".format(dbname, hostname, timestamp)
    es.index(index=index_name, body=doc, id=doc_id)

and the sdk doc:

Elasticsearch only stores data in UTC, you cannot change that and all you can do is store the UTC offset in the timestamp.
