Do you aware of Y2K38?

Okay let me first tell what is the term Y2K38 or Unix Millennium bug or year 2038 problem: Well it is a some kind of computer programming problem with date (something similar like Y2K), says that all programs and software are going to crash on near or after 2038. You will find a Wikipedia definition here. Okay look at some php code and its output:

$timestamp=mktime(0, 0, 0, 01 , 01, 2009);
echo date("F j, Y, g:i a",$timestamp);   // January 1, 2009, 12:00 am

Well output shows expected result. But notice this code now:

$timestamp=mktime(0, 0, 0, 01 , 01, 2039);
echo date("F j, Y, g:i a",$timestamp);  //January 1, 1970, 7:00 am

Yes output is little shocking. This is what they are calling Y2K38. I think we don’t need to worry about it too much. We still have enough time to solve this.  The code above is tested in php(5.2.9) language. I also tested the same thing in java and there is no such problem i found yet (yes java is great!!! ).

what could happen on 21 december 2012?

According to Mayan calender, Chinese ancient prediction, The Bible and lots of fortune tellers, the world is going to an end on 21 december 2012. According to NASA This date (December 21, 2012), is the day of the Winter Solstice, that means, In 2012 the next polar reversal will take place on earth. This means that the North Pole will be changed into the South Pole. Scientifically this can only be explained by the fact that the earth will start rotating in the opposite direction, together with a huge disaster of unknown proportions. To understand what i want to say here take a look at these video footage taken from History Channel.
