an increasing number like in SVN, which makes it very hard to determine at a
glance if a particular test pre- or postdates a revision one's interested in.

I see also that the reported timestamp, which looks like

 "Sun, 19 Jan 2014 06:08:04 +0000"

seems to indicate the time where the result file was generated, which is
of little use.

It is used to tell if the report generation is stalled.
