Hi,

I am using ELK GA 5.0.0. I am taking input from Kafka and I have a date field like `2018-03-23T13:14:33.419Z`. In my date filter, I am using the format;

```
date {
	match => ["log_time", "yyyy-MM-ddTHH:mm:ss.SSSZ"]
	timezone => "UTC"
	target => "@timestamp"
}

```

In the Logsash [date documentation](https://www.elastic.co/guide/en/logstash/5.0/plugins-filters-date.html), it is provided that Z is for Timezone offset structured as HHmm. How can I parse the date in this situation, or am I doing it right?

Thanks in advance.

Hi,

Try just matching with the standard ISO8601.

```
date {
    match => ["log_time", "ISO8601"]
  }

```

Hope this helps.
