FWIW, I'm used to the way it's shown and would not like a change, so
if this can be made user-settable as Magnus suggests, that would be
better IMO.

The real problem with that column though is that it relies on run start
times that are self-reported by the buildfarm clients, and some of them
have system clocks that are many hours off reality.  What *I'd* like to
see is for the column to contain time of receipt of the buildfarm report
at the server, less the measured runtime of the test.
