I am trying to find the elapsed time  
**elapsed time** : duration of time b/w `now` and `createdTime`

To pass the current\_time (ie `now`) I have added it to the `params`, and I can access that in the `source` field by writing `params['now']`  
The problem is that this value of `params['now']` is a string and not of type date

The below example works as I have added `doc['updatedTime']`, in place of `params['now']`  
how can I get it to work with `params['now']`

WORKING

```auto
GET entity.incident_action_item/_search
{
  "script_fields": {
    "timeElapsed": {
      "script": {
        "source": "doc['updatedTime'].value.toInstant().getEpochSecond() - doc['createdTime'].value.toInstant().getEpochSecond()",
        "params": {
          "now": "2022-03-31T17:18:28.153+0530"
        }
      }
    }
  }
}

```

NOT WORKING

```auto
GET entity.incident_action_item/_search
{
  "script_fields": {
    "timeElapsed": {
      "script": {
        "source": "params['now'].value.toInstant().getEpochSecond() - doc['createdTime'].value.toInstant().getEpochSecond()",
        "params": {
          "now": "2022-03-31T17:18:28.153+0530"
        }
      }
    }
  }
}

```

I have tried multiple combinations and tried different methods supported by the painless langauge, I was not able to get it work

I faced one or the other exception

This example below returns the difference of days between dates, you can edit to achieve your goal.  
The difference is that the currentdate is already in the millis.

```auto
GET index_002/_search
{
  "_source": [
    "name", "create_date"
  ],
  "query": {
    "match_all": {}
  },
  "script_fields": {
    "diff_dates": {
      "script": {
        "source": """
        Instant instant = Instant.ofEpochMilli(params.current_date);
        ZonedDateTime now = ZonedDateTime.ofInstant(instant, ZoneId.of('Z'));
        return doc['create_date'].value.until(now, ChronoUnit.DAYS);
        """,       
        "params": {
          "current_date": 1650516960000
        }
      }
    }
  }
}

```
