The "Last Commit" and "Added"-Columns in the forensics table show the date relative to the date of the build (e.g. 2 days ago). But when viewing the build information, I would expect the date to be relative to the current time. Otherwise one has to calculate the time of the commit by adding the time that has passed since the build, which I find to be quite cumbersome.
