Lease Plan took nine months to complete the conversion project, which ensured all its computer systems were year 2000 compliant. The year 2000 creates major problems for some older computer systems, and the prospect of an IT crash at midnight on December 31, 1999 are possible. The issue arises from the failure of some IT systems, whether software or hardware, to identify a date in more than a two-digit form.
As a result only the last two digits of a date are recognised, which means that when 1999 becomes the year 2000, the computer will be unable to adjust to a system which has apparently gone back in time, i.e. from 99 to 00.
