2^47/33e6 = 49.36 days. The value is so much off that makes me suspect that this is not the correct analysis, or at least that there are additional factors at play
exactly. you could find a plausible clock rate that rolls over in ~51 days with any number of assumed counter widths. this is not indicative of anything but guessing.
and there is no margin at all or negative margin, so clearly this is wrong. is the rollover period 52 days? 60? 90?
the whole article is a bunch of unsubstantiated speculation dressed up with lots of facts and details to distract ones attention.
