The name of the system field "decision date" in the code

Question

Hello! Please tell me the name of the system field "decision date", for example, "creation date" is {{issue.created}}, but I do not know the "decision date". Field {{issue.resolved}} - returns the solution field itself, but not the date. And I need a date. I will be very grateful. Thanks!

"Decision date" is not a system field, it's a custom field (added by an app or an administrator).  You'll need to use the custom field smart value.

For example, the formula {{issue.created.diff(now).minutes}} returns a value, but {{issue.created.diff(issue.decision.date).minutes}} does not work

Павел Копасов · Answer

I need to find the time to work on the task, I implement it through the mathematical formula {{[date1].diff([date2]).[unit]}} where date1 is the "creation date" field (issue.created), but date2 - there should be the value of the "decision date" field. For example (screenshot), the task was created at 7:46, and solved at 7:52 . Through this mathematical formula, I need to find these 12 minutes. Thanks!
