Convert timestamp into date

No, the fact that the timestamp has a Z at the end signifies that it is UTC. You can convert the timestamp into a local time using any Java-based method. For example:

            "timestamp_utc": {
              "script": {
                  "lang": "painless",
                  "source": """doc["timestamp"]"""
                }
            },
            "timestamp_local": {
              "script": {
                  "lang": "painless",
                  "source": """Instant.ofEpochMilli(doc["timestamp"].value.millis).atZone(ZoneOffset.ofHours(-5))"""
                }
            },

would yield:

          "timestamp_local" : [
            "2017-02-09T11:00:00.000-05:00"
          ],
          "timestamp_utc" : [
            "2017-02-09T16:00:00.000Z"
          ],
