"You're seeing some bad, bad reporting here. [...] I don't have access to the latest Hawkins paper, but what he does not do is look at a particular feature (e.g. a SN light curve) and show it does not appear more slowly in distant QSO's, but he lumps together all optical variations, does a Fourier transform and shows that the ensemble appears independent of distance. This is a much more complicated measurement, and it is much more difficult to interpret easily. [...] Any sort of one line conclusion like "QSOs don't exhibit time dilation" is oversimplistic."
This, plus my impression that every time I've seen a PhysOrg link on HN it's been sensationalized at best, inclines me to wait for more detailed information from more obviously-reliable sources before jumping to any conclusions.
