We have two months of history in our backlog, the dates issues closed etc. Accidentally every issue got opened so we had to close again, BUT our history now shows a huge spike of work to do in the charts and then it shows them all closed today, as we re-closed them. Resolved shows Today 4:30. We need to show Aug 29, 2012 as the closed issue date. I see no way to back date the closed. This is fairly important as our charts show the burn down rates, the velocity and are presented to our customer. Thanks.
