The date filter does not parse named zone, you should change your match to the one shared in the previous answer.

```auto
date { match => ["event_timestamp", "EEE MMM dd HH:mm:ss 'IST' yyyy"] }

```

Also, you will need to specify your timezone to the filter and you can't use named timezone as well because they can be ambigous, in your case, _IST_ can mean 3 completely different timezones, as explained in this [another question](https://discuss.elastic.co/t/logstash-mapping-logfile-time-to-timestamp/278772/4)

You will need something like this:

```auto
date { 
    match => ["event_timestamp", "EEE MMM dd HH:mm:ss 'IST' yyyy"] 
    timezone => "Asia/Kolkata"
}

```

Assuming that by _IST_, you mean `India Standard Time`, so you should use _Asia/Kolkata_ as the timezone.
