I have done some calculations and found that us humans have been counting leap years wrong in the past whatever years. It is not the year 2010 but instead 2509. The proof - check out the below php script which should display 2009 using timestamp ratios but instead displays a time in the future.
<?php $time=mktime(0,0,0,1,1,2020); $ratio=1980/40; $time=$ratio*$time; $year=floor($time/(360.25*24*60*60)); echo $year; ?>
So what are your opinions on this. I believe history is wrong and somebody has forgotten to add those leap years. Enjoy...;)
