How to get the sum of time spent on sub-tasks on the parent story

[John Bloom]

We are using a plugin that allows us to track time automatically on items that are put into the "in progress" state. Our workflow is to estimate the story but track time on the sub-tasks. Is there any way to get a sum of the time spent on all of the sub-tasks and store that on the story?

We use tshirt sizing for stories and my goal would be to build estimation reports based off of the average time a S, M, L, XL story takes. I just need to be able to roll up the time spent on sub-tasks to get a final time spent on the story.

Hi, John

Please review this thread https://community.atlassian.com/t5/Jira-Software-questions/Jira-Subtasks-do-not-update-parents-Time-Spent/qaq-p/43007

And, maybe, this https://community.atlassian.com/t5/Jira-questions/Script-to-calculate-sum-between-parent-issue-and-subtasks/qaq-p/735469

As far as I know, Jira does not have such functionality out of the box, so you need to use a custom script
