I am a QA and am constantly having to go to the developers asking them to guesstimate the time that their changes were merged in from the day before. It would be great if I could just see the times so that I could compare with Bamboo. 

DateUpdated_Yesterday shows that the column only says Yesterday.

DateMerged_Yesterday shows that the merged time only shows as Yesterday.

DateBuilt_RealTime shows that Bamboo tells you the exact time the last build was completed and how long it took.
