Hi there  
I have 2 Date fields **Field1** and **Field2** and **LABEL**. I need to have a visualization which is a list which shows the difference in seconds for all the items:

| **Items| timeTakeninSeconds** |  
|LABEL1| (Field2-Field1).seconds|  
|LABEL2| (Field2-Field1).seconds|  
|LABEL3| (Field2-Field1).seconds|  
....  
....

I tried with scripted field but come with error:  
Discover: class\_cast\_exception: Cannot apply [-] operation to types [org.joda.time.MutableDateTime] and [org.joda.time.MutableDateTime].

Can you please help me with this.

Regards,  
Ginu

Can you provide a copy of the script that you tried?

What version of kibana are you using?

Try adding [getMillis](http://www.joda.org/joda-time/apidocs/org/joda/time/base/BaseDateTime.html#getMillis--) to convert `MutableDateTime` to milliseconds

Hi  
I am using Version: 6.3.1  
my Script :  
doc['LastHeartbeatCheck'].value - doc['currentTimesStamp'].value

`type: number`  
`Format: Duration`  
`InputFormat: seconds`  
`OutputFormat: Human Readable`

the 2 fields (LastHeartbeatCheck, currentTimesStamp) are date fields... with value for eg  
LastHeartbeatCheck = August 9th 2018, 15:00:12.000  
currentTimesStamp=August 9th 2018, 15:00:12.000

Thanks Nathan for the idea of using .getMillis()

I update dthe script as follows and it worked:  
`doc['LastHeartbeatCheck'].value.getMillis() - doc['LastHeartbeatCheck'].value.getMillis()`

> doc['LastHeartbeatCheck'].value - doc['currentTimesStamp'].value
