インデックス作成APIを実行する際、タイムスタンプ型のフィールドに現在時刻を設定する方法があればご教示頂けないでしょうか？

以下の例でいうと、@timestampフィールドに現在時刻を設定したいです

```auto
PUT my-index-000001/_doc/1?timeout=5m
{
  "@timestamp": "2099-11-15T13:12:00",
  "message": "GET /search HTTP/1.1 200 1070000",
  "user": {
    "id": "kimchy"
  }
}

```

Ingest Pipelineと組み合わせて使うのではどうでしょうか？

### Ingest Pipelineの作成

```auto
PUT _ingest/pipeline/ingest_timestamp
{
  "processors" : [
    {
      "set": {
        "field": "@timestamp",
        "value": "{{_ingest.timestamp}}"
      }
    }
  ]
}

```

### PUT

Ingest Pipelineを指定してPUTしています。

```auto
PUT my-index-000001/_doc/1?pipeline=ingest_timestamp
{
  "message": "GET /search HTTP/1.1 200 1070000",
  "user": {
    "id": "kimchy"
  }
}

```

### 得られる結果

> GET my-index-000001/\_doc/1

```auto
{
  "_index" : "my-index-000001",
  "_type" : "_doc",
  "_id" : "1",
  "_version" : 1,
  "_seq_no" : 0,
  "_primary_term" : 1,
  "found" : true,
  "_source" : {
    "@timestamp" : "2021-06-13T13:58:04.669824600Z",
    "message" : "GET /search HTTP/1.1 200 1070000",
    "user" : {
      "id" : "kimchy"
    }
  }
}

```

@timestampにUTCの時間が入っていることが確認できました。
