How can one find the delivered date of a change set
Accepted answer
If you show the history of a component in the Eclipse based RTC, you can hover over the change set icon and get a hover that shows both the modify date and the date the change set was added to the change history. This may not be quite what you want since change histories can be shared across workspaces and streams so the date may not apply to all streams (see https://jazz.net/jazz/resource/itemName/com.ibm.team.workitem.WorkItem/113130 for the details).
Note: Read David's comment below for a summary of a feature that was added in RTC 5.0.1 that also provides this information.
