On This Day - November 27th 1998
United States nuclear weapons begin being tested for possible year 2000 problems.
As the world neared the end of its second recorded millennium, there was a growing awareness of the possibility that computers could strike a problem. The year 2000 problem, or millennium bug, was a flaw in computer program design that caused some date-related processing to operate incorrectly for dates and times on and after January 1, 2000. Due to lack of foresight by computer programmers in the preceding decades, many commands depending on date were written with a two-digit year (eg 98 for 1998) instead of a four-digit year. It was conceived as a possibility that computers might interpret 00 as 1900 instead of 2000. It was feared that critical industries such as electricity, for example, and government functions would stop working at 12:00am on 1 January 2000.
On 27 November 1998, officials from the Pentagon in the USA stated that US nuclear weapons were being tested for potential Year 2000 problems, after it was recently discovered that up to a quarter of existing nuclear weapons systems had not been tested for year 2000 (Y2K) compliance. In the end, there were no major disasters as a result of the millennium bug, and the entire turnover was seen a non-event.
