### Description When importing issues from JIRA I would like to set the closed at date on an issue so the burndown chart is accurate. ### Proposal Edit Issue API should have a closed_at parameter or honor the updated_at parameter when doing a state_event: 'close' I was hoping that doing a state_event: 'close' with updated_at: 'some time in the past' would set the closed_at date so my burndown chart would look good but closed_at is always set to the current time. ### Links / references [Edit Issue](https://docs.gitlab.com/ee/api/issues.html#edit-issue)
