Hello guys. Hope you are doing well.
Im having a little problem trying to convert an event time in epoch to a readable timestamp, per example in UTC.
So, the log that i have is something like this:
```auto
event_time=1613523594666851230
```
So, i did apply a filter like this to my logstash config:
```auto
mutate {
convert => { "event_time" => "string"}
}
date {
match => ["event_time","UNIX_MS"]
target => "event_time"
timezone => "UTC"
tag_on_failure => [" "]
}
```
And then im getting the event time showing up like this, completely wrong:
```auto
event_time : 51132497-04-06T22:34:11.230Z
```
Hopefully you can help me, thank you for your time 🙂 .

Your timestamp is in nanoseconds, not milliseconds. You could try
```
ruby { code => 'event.set("event_time", event.get("event_time").to_f/1000000)' }
```
