Seems like we are experiencing this too -> http://forum.piwik.org/t/update-to-2-15-changed-average-visit-duration-and-time-on-page/16744 

@tsteur : from 2.14.3 to 2.15.0 And this is just one of 800 Sites tracked in one Piwik instance. (it has effect on the other 799 too)

Main Question is: which counting is correct?
