We've used the 1970 window since at least as far : back as 1994. It was "intented" and patented in Feb 1995: : http://www.washingtonpost.com/wp-srv/WPlate/1999-12/17/081l-121799-idx.html I saw the window prior art as far back as the 1970s when reading about the 2 digit date problem, as it was know at the time. And I know my professors in college in the mid 80's mentioned it as well. If anybody hassles us, I'll dig up my notes. Also, NPR had a story of an old Cobol programmer talking about using this in the late 60s/early 70s when the first 30 year bonds to cross the centry line... Even if this person had patented the technique at the time, that patent would have long expired by now. And they couldn't patent it at the time.
