Use getlocal instead of getutc.

Hi,

I have a problem in the Kibana search which don't returns the good index after midnight because of timezone.

For example : My event is created with the timestamp "2013-04-30 00:28:01 +0200". I would like to see the event in Kibana, but it search in logstash-2013-04-29 (yesterday), no in logstash-2013-04-30 (today).

I change getutc to getlocal and it works. Is there a reason to use getutc ?
