   * Configures the current validator.

   *

   * Available options:

   *

   *  * date_format:             A regular expression that dates must match

   *                             Note that the regular expression must use named subpatterns like (?P<year>)

   *                             Working example: ~(?P<day>\d{2})/(?P<month>\d{2})/(?P<year>\d{4})~

   *  * with_time:               true if the validator must return a time, false otherwise

   *  * date_output:             The format to use when returning a date (default to Y-m-d)

   *  * datetime_output:         The format to use when returning a date with time (default to Y-m-d H:i:s)

   *  * date_format_error:       The date format to use when displaying an error for a bad_format error (use date_format if not provided)

   *  * max:                     The maximum date allowed (as a timestamp or accecpted date() format)

   *  * min:                     The minimum date allowed (as a timestamp or accecpted date() format)

   *  * date_format_range_error: The date format to use when displaying an error for min/max (default to d/m/Y H:i:s)

   *

   * Available error codes:

   *

   *  * bad_format

   *  * min

   *  * max

   *

   * @param array $options    An array of options

   * @param array $messages   An array of error messages
