I have net flow data that's DateTime is in local timezone (GMT+10). However when elastic search creates the index it assumes that the data is in UTC, therefore all my times are skewed. Just wondering if there is a way to say to elastic search that the data is in local and not UTC?
The `@timestamp` is in the correct format and timezone, however the field `tm` is completely skewed.

ES assumes UTC by default and then Kibana converts to the local browser TZ. If you are using Logstash then you can tell it how to ensure the [ES encoded timestamp contains the TZ](https://www.elastic.co/guide/en/logstash/current/plugins-filters-date.html), otherwise just make sure you [pass it in so that ES can handle it appropriately](https://www.elastic.co/guide/en/elasticsearch/reference/2.3/date.html).
