Show absolute dates instead of relative dates in the UI
"One month ago" is not really very useful. Show the actual date and time a build was run. Maybe use relative times for things less than 24 hours ago where a relative time provides at least some precision but for anything more than a day the lack of precision and difficulty of converting to an actual date to correlate with other sources means that real dates are much more useful.
