That's in 64.3k blocks, so at 6*24 = 144 blocks/day, we'll be there in about 450 days or ~15 months.

That is estimating the probability distribution for the change and throttle the hashrate collectively (the more people participate the more accurate it will be) by a few fractions of a percent so that the probability we will hit 21.dec.2012 23:59:59,999999 will be maximized

Why
