How to change timestamp adding by logstash while sending logs to output plugin

[aksshm]

Hi, I'm running logstash with kafka as input plugin and syslog as output plugin.
For kafka , all the messages are with local timezone/required timezone but while sending to syslog logstash is adding a timestamp in front of each message(i.e in UTC). How can i change those timestamp?

ex:

Aug 13 05:43:41 REDIS-LOG {"kubernetes":{"pod":{"uid":"ac360b5a-2dc5-459f-8c3b-e0eb236d31fc","name":"redis-master-67c9ffcd9f-tvmvb"}},"ecs":{"version":"1.1.0"},"agent":{"hostname":"filebeat-z7z6r","version":"7.5.1","ephemeral_id":"8f1310ba-4512-40f3-9406-0672fb8bd63f","type":"filebeat","id":"21f6b5b4-71d5-4a19-8341-996a66cef946"}

The syslog output unconditionally (in both the if and the else branches) adds a timestamp based on @timestamp, which is normally UTC. If you want the syslog timestamp to be in a different timezone you will have to change the timezone of @timestamp.

You will need to change the filter configuration. You cannot do it in the yml.

filter configuration you mean filter plugin? if yes, then we can add filter plugin in yaml right?
or can we remove this parameter completely, anyways we have timestamp in the messages so we don't need this @timestamp parameter..

@timestamp is required.
