A funny thing about the people who think that 2016 blocks per difficulty adjustment is only a veiled reference to the law that the US government used to claim all gold from its citizens for the Bretton Woods agreement.
If you count time forward from midnight, the beginning of January 1st, 1970, the official unix timestamp zero value, in fact, an anagram of this number also will appear:
60x60x24 = 86400 (one day)
86400*365.25 = 31557600 (one year, normally one day added on every 4)
2^32/31557600 = 136.099300834
This works out to the year 2106. To be strictly precise, it would be approximately 36 days and ~6 hours, so it would be somewhere very close to 6am on February 5th, 2106
Anyway, 2106. By this date, the Bitcoin block must increase its timestamp precision by at least 1 bit to get us to 2242.
