The date filter's timezone offset match not working?

[helloEson]

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.

@magnusbaeck Thanks for your response. What should i do if i want to reserve the original timezone?

[magnusbaeck (Magnus Bäck)]

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