						hosts => localhost	  	
						index => "logstash(%{+yyyy.MM.dd})"  
						document_type =>"logstash"
		}   
		stdout {  
            codec => rubydebug

The `%{+yyyy.MM.dd}` notation always uses UTC. You can use a ruby filter to store whatever date format you want in a `@metadata` field and reference that instead. This has been discussed many times before so please search the archives.
