Time of Last Status Change
Use this built-in script field to display the date and time an issue's status was last changed. For example, if an issue's status was last changed from To-do to Done, this field will display when this change occurred.
Note: This script field will display a status change if the status of an issue is transitioned to the same status, for example from To-do to To-do.
Using this build-in script field
Note: This built-in script field is automatically applied globally, however, you can configure the context and screens as you like.
