event.get("@timestamp").to\_f returns the number of seconds since the epoch (.to\_f includes fractional seconds). You can format number of second since epoch as a date using strftime

```
    ruby {
        code => '
            t = Time.at(event.get("@timestamp").to_f)
            event.set("someField", t.strftime("%Y-%m-%d"))
        '
    }
```
