---------------------------------------------------------------
I made some initial analysis on this more than year ago (MNG-5729). I would
involve to change a lot of spots. This should not happen before 3.4 or even 4.0
and how critical is this? Given that Maven is not a long-running process and
this has been reported only once, I'd say this is low priority. We have other
important issues. I am currently loaded with Doxia Sitetools 1.7 preparations
anyway.
If you have some spare time, give it a try in a branch 'MNG-5729'. More
interestingly, how can we create a proper IT for that?

> Reporter: Christian Jung
> Priority: Minor

> In issue MNG-5623 we reported an exception when printing the reactor summary
> if one of the times was negative.
> I saw in one case, that the overall maven build time, as measured from
> outside (i.e. by our QuickBuild system) was -10.8 seconds. The corresponding
> reactor summary was:
> {code}
> 13:55:25,184 INFO - Reactor Summary:

> The thing is quite hard to reproduce, the machines were virtual machines that
> have been running for quite a long time.
> Our administrators suspected that just at this point, the local clock was
> synchronized with some outer source.
> We should check if such negative durations can be avoided, and if not, they
> should be handled correctly.
