Y2K

The general class of problems resulting from the wrapping of computers' internal date timers is given this label in honor of the most obvious occurrence: when the year changes from 1999 to 2000. Contrary to popular belief, these problems will not all manifest themselves on the first day of 2000, but will in fact happen over a range of dates extending out beyond 2075. A computer that does not have problems prior to the beginning of 2001 is considered "Y2K compliant", and a computer that does not have problems within the next ten years or so is considered for all practical purposes to be "Y2K clean".
