I was watching this video from Neil deGrasse Tyson where he explains just how rich Bill Gates is (it's a fun video to watch, check it out here: http://9gag.tv/p/a5XWnk/watch-neil-degrasse-tyson-explain-how-rich-bill-gates-is). In it, he talks about how old you will be when you've reached your billionth second (it's close to 32 years, BTW), and mentioned having taken the time to compute this, and that someone will probably write an app to do this.
So of course, I said "that should be easy enough for PowerShell!". It was. Ridiculously easy, in fact. So, for some fun, you, too, can quickly calculate when you can celebrate your billionth second! (I used some sample data not actually linked to anyone's birthday that I know)
