  | `target_field`         | no        | @timestamp          | The field that will hold the parsed date.
  | `formats`              | yes       | -                   | An array of the expected date formats. Can be a Joda pattern or one of the following formats: ISO8601, UNIX, UNIX_MS, or TAI64N.
  | `timezone`             | no        | UTC                 | The timezone to use when parsing the date.
  | `locale`               | no        | ENGLISH             | The locale to use when parsing the date, relevant when parsing month names or week days.

  | `ignore_missing` | no        | `false`  | If `true` and `field` does not exist or is `null`, the processor quietly exits without modifying the document
