Hello,

Is there a way for me to assign the timestamp value to an add\_field? Like for example:

```auto
processors:
- add_fields:
    fields:
      collectiontime: "@timestamp"

```

This example doesn't work because when I check the debug log I see a:

"collectiontime":"@timestamp"

and I really want:

"collectiontime":2022-01-29T05:36:14.656+0530"

ie, the actual time.

or maybe there is a way to call a Linux command, like:

collectiontime: %{date}

where 'date' is the Linux command (I am sure I have the format wrong)

Thanks!
