You need to use the date filter - [https://www.elastic.co/guide/en/logstash/current/plugins-filters-date.html](https://www.elastic.co/guide/en/logstash/current/plugins-filters-date.html)
A match pattern like `MMM dd HH:mm:ss` would work, then when you integrate that into the filter it'll add the date and make it ISO8601 format.

i tried to add the date filter
```
date {
locale => "en"
match => ["received_at",
"MMM d HH:mm:ss YYYY",
"MMM dd HH:mm:ss YYYY","ISO8601"
]
add_field => ["time" , "%{YYYY-MM-dd HH:mm:ss}" ---> how to get the receive_at and convert the format ?
}
```

with my date filter
```
date {
locale => "en"
match => ["timestamp",
"MMM d HH:mm:ss.SSS YYYY",
"MMM dd HH:mm:ss.SSS YYYY",
"ISO8601"]
}
```
it's didn't get any error
but the timestamp didn't convert the format
from
```
May 4 11:49:19.701 2016
```
to
```
2016-05-04 11:43:19.701
```

The date filter by default populates the `@timestamp` field with the parsed date, and does not update the field that was parsed. You can change this by specifying a target field.
