Hi Team

getting below error in parsing the date in logstash. Kindly suggest how this can be resolved.

```auto
"error"=>{"type"=>"mapper_parsing_exception", "reason"=>"failed to parse field [ResponseTime] of type [date] in document with id '32KUH4gB96hGxKLH90gP'. Preview of field's value: '15/05/2023 18:52:60.000'", "caused_by"=>{"type"=>"illegal_argument_exception", "reason"=>"failed to parse date field [15/05/2023 18:52:60.000] with format [strict_date_optional_time||epoch_millis]", "caused_by"=>{"type"=>"date_time_parse_exception", "reason"=>"Failed to parse with all enclosed parsers"}}}

```

Below is the config for conversion

```auto
    date {

        match => ["RequestTime", "dd/MM/yyyy HH:mm:ss.SSS"]

        target => "RequestTime"

    }

    date {

        match => ["ResponseTime", "dd/MM/yyyy HH:mm:ss.SSS"]

        target => "ResponseTime"

    }

```

Each occurrence is at 000 millisecond and failing with above error.

18:52:60 with 60 seconds should have rolled over to 18:53:00 unless there was a leap second in that minute. A leap second would only occur at the end of the month, so that time appears to be invalid.
