How to adjust or change duration of a task under an epic in the timeline

[Themiya Dharmathilake]

When creating a time line, jira provides editing or changing the time of the Epics. but when a child issue is added to a relevant epic in the timeline, jira does not allow to change the time. it is automatically set to the sprint time line which the issue is included. 

Tried out by adding "Start Date" and "End date" configurations to the issues. but still the gantt chart is not changing and also the expandable icon appear when the mouse pointer hovers in the end of the pillar in epics are not appearing for child issues. 

can I know that is there any change in settings or a permission to be granted to enable this feature to create timelines.

Hello @Themiya Dharmathilake 

Welcome to the Atlassian community.

In the Timeline associated with a Scrum board the issues can be scheduled either automatically based on the sprint(s) to which they get assigned or based on Start and Due dates. You can change this setting by clicking the ... button in the upper right corner of the Timeline view and selecting Configure Timeline.
