Perhaps you're Right! But I find it Hard to Imagine how Rush could have it So Wrong! (After All, -He Always says!, -that he is Hardly Ever Wrong!)(Smile Emoticon).
I do know from my Longtime Astronomy Interest and Hobby, -that there are 86,400 seconds in a Day. So 10 days would make for 864,000 Seconds. 100 days, 8 Million and 640,000 seconds. This is now the Better Part of a Third of a Year. Three times that, -or 300 Days, -would, -roughly Rounding now, -be some 25 million Seconds. Now so Adding into Account the Additional 65 days of a Year, -I Ruffly Round to some 30 Million Seconds. In a Year. So 10 Years thereabouts would be Roughly some 300 Million Seconds. 30 Years = some 900 Million Seconds. Just a Little More would make for your Billion! 31.7 Years would BE that Little More!
And so!, -YOU are Right! And Rush, -I am Sorry to Say, -is Wrong! As well as whereever he Got that from!
