Comment (by arthuredelstein):

 Replying to [comment:5 gk]:
 > The values in the description are explained by https://hg.mozilla.org
 /mozilla-central/rev/a5679c8bc3fe. The changes (`return 0` -> `return
 mZeroTime`) in nsPerformance.cpp are causing this. What bothers me is the
 example in comment:1 as it shows the behavior for `dom.enable_performance`
 = `false` looking at the last 5 values...

 Yeah, it's weird. Unfortunately I don't know how I did it! :P Anyhow,
 seems like it's probably best to set everything to 0?
