Q: how to define timezone in logstash timestamp Below is my code, I'm parsing event_date to timestamp.
date {
    match => [ "event_date" ,"yyyy-MM-dd HH:mm:ss"]
    target => "@timestamp"
}

I have also tried below code
date {
    match => [ "event_date" ,"yyyy-MM-dd HH:mm:ss"]
    timezone => "Europe/Istanbul"
    target => "@timestamp"
}

But none of them worked fine.
event_date is

2018-10-20 12:23:46

but timestamp returns

2018-10-20T09:23:46.000Z

The difference is about timezone. Turkey timezone is

GMT+03:00

How can i set it ?
Thanks for answering.

A: I have tried to change timezone as Istanbul but not working fine. Instead of giving Timezone area we can also define time difference like below

timezone => "-0000"

That solved my question.
