Calculate lifetime of a product



I would like to calculate the lifetime of a product based on the difference between when the product has been released (custom field Launch date) and now.

I was trying to do it with the duration scripted field in scriptrunner but I have an issue : 

((System.currentTimeMillis() - customField[14311].getTime())/1000).toLong() 


Here is the error message :

 groovy.lang.MissingMethodException: No signature of method: com.atlassian.jira.issue.fields.ImmutableCustomField.getAt() is applicable for argument types: (Integer) values: [14311] Possible solutions: getAt(java.lang.String), getId(), getName(), putAt(java.lang.String, java.lang.Object), wait(), grep() at



Can anyone help ?

Thank you

I figured it out, here is the final code :

((System.currentTimeMillis() - getCustomFieldValue('Launch Date').getTime())/1000).toLong()

Thanks for your time Ravi :)

Hi @Arthur S 

There are few ways of doing it.

The snippet below has a method which I use a lot for date calculation.

def duration = TimeCategory.minus(
new Date(),

However the script on the page match closely to your requirements.


Hi @Ravi Sagar _Sparxsys_ ,


What I am trying to do is to create a custom scripted field on "Duration" template.

When I do it this way :

((System.currentTimeMillis() - issue.created.getTime())/1000).toLong()

I have the following result :

48 weeks, 13 hours, 36 minutes 


But instead of comparing it to the created date, I would like to compare it to my custom field "Launch Date". 

For my understanding, this is giving me the field value : 


but I am not sure how to convert it to the right type to compare it to System.currentTimeMillis()
