What format should I be using?

Hello @savvy

On 7.x, the date formats must be converted to Java Time as detailed here

You can use the following tool to convert the formats from Joda to Java time: https://esddd.herokuapp.com/

DELETE timenanos
PUT timenanos
{
  "settings": {
    "index": {
      "refresh_interval": "5s"
    }
  },
  "mappings": {
    "properties": {
      "abc": {
        "properties": {
          "timestamp": {
            "format": "uuuu-MM-dd HH:mm:ss.SSSSSSSSS X||yyyy-MM-dd'T'HH:mm:ss.SSSSSSSSSX",
            "type": "date_nanos"
          }
        }
      }
    }
  }
}

POST timenanos/_doc/1
{
  "abc": {
    "timestamp": "2020-05-06T01:46:37.357884414Z"
  }
}
POST timenanos/_doc/2
