Hi 😄
## TL;DR
## logstash won't parse date field; date field parsed as string...
I'm trying to parse my date field using logstash date filter
> **[Date filter plugin | Logstash Plugins](https://www.elastic.co/docs/reference/logstash/plugins/plugins-filters-date)**
>
> Plugin version: v3.1.15 (Other versions), Released on: 2022-06-29, Changelog. For questions about the plugin, open a topic in the Discuss forums. For...
but with no success...
looks like it is not override the @timestamp field and also when using other target field it is written as a string field and not a date field.
my input + filter looks like this:
> input {
> beats {
> port =\> 5044
> codec =\> "json"
> }
> }
> filter {
>
> date {
> match =\> ["time" , "ISO8601"]
> #target =\> "parsed\_date" # when using this the "parsed\_date" field creates as type of string
> }
> }
and my log line (fired by filebeat) looks something like this:
{ "time":"2017-06-20T16:22:24.4233978Z","id":"025c4c1c65","type":"Error","message":"some message" }
when looking in logstash logs there is no errors at all relating to this plugin.
also there is nothing in the tag of the indexed document telling there was a parsing error or something like that.
am I missing something ?
thanks in advance for any help 🙂

Please show what you get in ES for the sample log line above. Copy/paste from the JSON tab of Kibana's Discover view.

That's expected. It's mostly ES that determines the type of fields.

Hmm, this looks correct. I don't know what's going on.

OK I think I get it, Kibana adjust the timezone to the browser timezone does it ?
there is a way to change that ?
