Hmmm, thinking about it, this sounds very much like Y2K...where all the computers were gunna explode because they couldn't compute 1/1/2000 and they'd just go to 1/1/19001 :L
It was a binary error. Several computers didn't understand that after 1999 came 2000 instead they went 19100 don't ask me..binary is not my thing lol. But this will be similar as long as we know how to fix it quickly we'll be fine.
