Hi ,  
Is there a way to change the mapping field to timestamp ?

This is my input "Time :2022-11-21 12:01:30.85"

I'm using "dissect \> mapping" to map this field, but the output data type is "text" and I want it as a timestamp .

my conf ..

```auto
filter {
  dissect {
    mapping => {
      "message" => "Time :%{TIMESTAMP_ISO8601}
    }
  }
}

```

Use a [date filter](https://www.elastic.co/guide/en/logstash/current/plugins-filters-date.html) to parse it.
