Logtrail : Kibana plugin to view, search and tail logs

@sivasamyk On kibana UI, I see my local time, IST against the logs.

I am using this conf

{
"es": {
"default_index": "logstash-",
"allow_url_parameter": true,
"timezone": "Asia/Kolkata"
},
"tail_interval_in_seconds": 10,
"max_buckets": 500,
"nested_objects" : false,
"default_time_range_in_days" : 2,
"fields" : {
"mapping" : {
"timestamp" : "@timestamp",
"display_timestamp" : "@timestamp",
"hostname" : "localhost",
"program": "
",
"message": "message"
}
}
}

I think I need to change display timestamp somehow or the timezone. Please help
