Hello!

I have a `@timestamp` field that is created from two other fields. That works fine.

Kibana also updates the timezone automatically (from what I read). That also works fine.

I have a new field `HOUR` that has been created from the @timestamp field using strftime. That works fine as well.

Here's my issue: The `HOUR` field is using the UTC time. How can I change it to America/Chicago?

Here's my code:

```
ruby {
	code => "event.set('[DAY]',event.get('@timestamp').time.strftime('%a'))
	event.set('[DAY_OF_MONTH]',event.get('@timestamp').time.strftime('%d').to_i)
	event.set('[HOUR]',(event.get('@timestamp').time.strftime('%H').to_i))"
}
if [source] =~ "table" {
    mutate{ add_field => {
        "[@metadata][timestamp]" => "%{SMF30DTE} %{SMF30TME}"
    }}
    date{
		match => ["[@metadata][timestamp]", "yyyy-MM-dd HH:mm:ss:SS"]
		timezone => "America/Chicago"
		target => "@timestamp"
	}
}

```

Here's the output in Kibana:

```
Time DAY_OF_MONTH HOUR @timestamp   
13:58:23.430 4 20 November 4th 2019, 13:58:23.430

```

^^ The HOUR field should contain 13, not 20.

(I've gone through the documentation but it's really not that detailed, nor does it provide any examples.)
