Hi,

I am using ELK GA 5.0.0. I am consuming from Kafka and I have a message in which has date like `05-Feb-2018:10:39:33 +0000`. I used grok filter to parse date like;

```
date {
	match => ["datetime", "dd-MM-YYYY:HH:mm:ss Z"]
	timezone => "GMT"
	target => "@timestamp"
}

```

but it is creating `_dateparsefailure`. I refered this page [https://github.com/logstash-plugins/logstash-patterns-core/blob/master/patterns/grok-patterns](https://github.com/logstash-plugins/logstash-patterns-core/blob/master/patterns/grok-patterns) to create the pattern. Why is this error happening and how can I fix this?

Thanks.

Use MMM to match the name of a month, not MM.

Really? Grok patterns have nothing to do with date patterns.
