Time as a Microcosm: Was the Year 2000 Crisis Inevitable?
The widespread use of YYMMDD as the date format of choice in information systems
caused worldwide anxiety at the turn of the millennium, costing untold billions of dollars
in remediation to ensure that systems would continue to function. Once this
particular data format choice was selected, the need for remediation was inevitable.
However, were the rationales for selecting this particular format ever valid?
This presentation will use Time-of-Year formats as a microcosm of the issues
which need to be considered when deciding on architectural and data structuring,
format, and representation. Time-of-Year formats have been an ongoing source
of such problems. Issues which should be considered when making architectural
decisions will be highlighted, and their implications discussed.
This is the closing presentation of a three-presentation visit to Los Alamos by
Mr. Gezelter. On Tuesday and Wednesday evenings, Mr. Gezelter will be making
presentations on network security issues at the Mesa Public Library and the
Los Alamos Chamber of Commerce.
