Hello,

I have a time field like this:  
"time\_local" =\> "23/Nov/2017:18:54:31 +0800"

And i want to use date filter to extract it to field @timestamp, so i have the filter pattern like this:  
date {  
match =\> ["time\_local", "dd/MMM/yyyy:HH:mm:ss Z"]  
}

But what i got the result looks like this:  
"time\_local" =\> "23/Nov/2017:18:54:31 +0800",  
"@timestamp" =\> 2017-11-23T10:54:31.000Z,

The letter Z does not recongized by date filter?

Thanks guys.

No, this is fine. The "Z" at the end of the `@timestamp` value just indicates that the timezone of the timestamp is UTC.

`@timestamp` is always UTC. This is not configurable. This topic has been discussed many times before, please check the archives.
