For the Unix geeks in the crowd….
As of 6:31:30PM ET this afternoon it will officially be 1234567890 Unix time, which started at zero and has been counting seconds since the stroke of midnight on January 1, 1970, not counting leap seconds. In case you’ve got other plans and can’t celebrate the milestone, I’ll see you December 22, 2282 at 3:13:30PM ET for the celebration of 9876543210.
