</div>

my json log is :

> {  
> "fileid": 203936363,  
> "timestamp": 1464187170,  
> "pubTime": 1464172574,  
> "reads": 111  
> }

my current filter is:  
filter{  
date {  
match =\> ["timestamp", "UNIX"]  
}  
}

now i wish copy the "pubTime" to new field "pubTime\_new" , look like "May 25th 2016, 18:36:14.000" in kibana, and my timezone is +08:00 "Asia/Shanghai"

hope show results in kibana：

@timestamp May 25th 2016, 22:39:30.000  
pubTime 1464172574  
pubTime\_new May 25th 2016, 18:36:14.000  
reads 111

Per [https://www.elastic.co/guide/en/logstash/current/plugins-filters-date.html](https://www.elastic.co/guide/en/logstash/current/plugins-filters-date.html)

```auto
filter{
date {
match => ["pubTime", "UNIX"]
target => "pubTime_new"
}
}

```
