Calculate two smart values containing dates

[Tomas Slavkovsky]

I am trying to create an automation for how long an issue was in progress. I have two dates now stored as a variable. How I can now show the difference without saving those dates. Alternatively, how I can store those values in the issue without making it visible to other users?

I tried: 

1. Jira smart values - date and time / https://support.atlassian.com/cloud-automation/docs/jira-smart-values-date-and-time/

{{[date1].diff([date2]).[unit]}}

2. Jira smart values - math expressions

{{#=}}......{{/}}

Any hint?

From log you can see, I am getting the correct date values.
