Can someone help me with the following?

I have a timestamp like this, and want to create it in Elasticsearch in a datefield.  
Apr 25, 2019 12:21:19,783 AM CEST

I keep getting errors with unrecognized date format and tried many formats.  
The 783 in this case are milliseconds.

Steps that I tried with the following:

```
PUT _template/template_testindex
{
  "index_patterns": ["testindex"],
  "settings": {
    "number_of_shards": 1
    },
    "mappings" : {
      "doc" : {
         "properties" : {
          "timestamp" : {
            "type" : "date",
            "format": "MMM d, yyyy K:m:s,S a z"
          }
      }
    }
  }
}
 
PUT testindex/_doc/1
{
  "timestamp": "Apr 25, 2019 12:21:19,783 AM CEST"
}
```

Hey Peter,

Try

```auto
DELETE foo

PUT foo
{
  "mappings": {
    "properties": {
      "date": {
        "type": "date",
        "format": "MMM dd, yyyy HH:mm:ss,SSS a z"
      }
    }
  }
}

PUT foo/_doc/1?refresh
{
  "date": "Apr 25, 2019 12:21:19,783 PM CEST"
}

GET foo/_search
{
  "query": {
    "range": {
      "date": {
        "gte": "2019-04-25",
        "format": "strict_date_optional_time"
      }
    }
  }
}

```

Note, I don't think your AM date in combination with `12:something` is valid.

Note 2, tested under Elasticsearch 7.0.

Hope this helps!

Thanks Alexander. I will try this in a bit. Will try it with the real data. I created this string online with a pattern generator.

The production data will be oke I assume at this time.
