- How can I change the @timestamp match my timestamp?
Please don't. Store the timestamps in UTC and leave the timezone adjustments to presentation layers. You are spending time on solving a problem that doesn't exist.
- Can I set timezone in the Kibana?
I believe Kibana always adjusts the UTC time to the browser's timezone. In Kibana 3 this is optional but in Kibana 4 I don't think you can turn it off.
