Qué (quién) es year 2000 - definición

<programming> (Y2K, or "millennium bug") A common name for all the difficulties the turn of the century, or dates in general, bring to computer users. Back in the 1970s and 1980s, the turn of the century looked so remote and memory/disk was so expensive that most programs stored only the last two digits of the year. These produce surprising results when dealing with dates after 1999. They may believe that 1 January 2000 is before 31 December 1999 (00 < 99), they may miscalculate the day of week, etc. Some programs used the year 99 as a special marker; there are rumours that some car insurance policies were cancelled because a year of 99 was used to mark deleted records. Complete testing of date-dependent code is virtually impossible, especially where the system under test relies on other systems such as customers' or suppliers' computers. Despite this, the predicted "millennium meltdown" never occurred. Various fixes and work-arounds were successfully applied, e.g. time shifting. And yes, the year 2000 was a leap year (multiples of 100 aren't leap years unless they're also multiples of 400). {PPR Corp Y2K FAQ (http://pprcorp.com/y2k/y2kfaq_j97.html)}. (2003-08-15)

The 2000 Year Old Man is a comedy sketch, created by Carl Reiner and Mel Brooks in the 1950s and first publicly performed in the 1960s. Brooks plays a 2000-year-old man, interviewed by Reiner in a series of comedy routines that were turned into a collection of records and also performed on television.

The year 2000 problem, also known as the Y2K problem, Y2K scare, millennium bug, Y2K bug, Y2K glitch, Y2K error, or simply Y2K refers to potential computer errors related to the formatting and storage of calendar data for dates in and after the year 2000. Many programs represented four-digit years with only the final two digits, making the year 2000 indistinguishable from 1900.
