On that first link is a date, it displays for me

"February 3 19122"

Took a look to see what's up with that (I'm not familiar with javascript) but it looks like he was using a function that returned the number of years since 1900, with the "19" hardcoded. So for 1995-1999 it would've worked fine, but since 2000 it has been 19100, 19101, etc.
