What was Y2K problem? How was it solved?

Question

Thanks for all the answers.

Answer 1

Problem was about because of some mal-programming all dates after 31st january,1999 was becoming wrong or wiered and that is why all code with that regards needed a change. The major issue was to do it in timely manner before 1st jan,2000. SO it was called year 2000 problem (Y2k) problem. You can find more information about this on http://en.wikipedia.org/wiki/Year_2000_problem

Answer 2

Earlier in the early 50- 60 s computer memories were very expensive , so programmers tried to save as much as they could on memory and hence for all programs using date generally only 2 fields were allocated to the year. eg. 1965 was entered as 65 , so a program in use in 1966 , which is say calculating interest for one year will subtract 66-65 and credit one year interest. It worked great until year 2000 came , when 00 will be lesser than all preceding nos. So they had to switch over to a four digit format for year.
Most of the problem was solved by re-writing the code to support the 4 digit format and some through patches and fixes.

Answer 3

It was a problem with how computers stored the year. Because RAM used to be prohibitively expensive the year was only saved as a two digit number ie 1995 would be 95 but with the turn of the century all of a sudden that 95 could be 2095. It was thought that some critical safety systems might crash or go to an unsafe configuration because of the changeover to 20XX dates. Many pieces of equipment were not able to roll over to 20XX dates but registered them as 19XX. Now dates are kept in a fuller form.
