I get log messages like this one:

```auto
Jul 20 14:15:29 ...
```

and I want to use grok filter (INGEST NODE in ElasticSearch) to extract timestamp (time and date) from this log in format like @timestamp (not string) . It necessary for me because I want to sort logs. Please, write down this filter.  
NOTE: This variant does not work:

```auto
%{TIMESTAMP_ISO8601:timestamp}
```
