SESSION 2 - Understanding the Problem
The
Nature of the problem, Chris Sammut, Divisional Manager Information
Technology Division, MITTS
Chris Sammut introduced
his presentation by saying that the Y2K problem was analogous
to the Titanic (your organisation), Captain (yourself), Iceberg
(1st January 2000) - some boarded the lifeboats and some drowned.
He said that the
scope of the problem was immense covering application software
(PC and server based applications), hardware (PCs, servers, network
equipment etc.) and embedded and control systems (controllers,
medical equipment etc.). The problem arose because of the two-digit
representation of the date coupled with the fact that 1700, 1800
and 1900 were not leap years but the year 2000 is. In addition,
the formatting of the date was different in the United States,
the United Kingdom and Europe; very few systems conformed to the
ISO 8601:1988 date display system of yyyy-mm-dd.
He said that, having
determined the size of the problem, there were three main solutions
- convert all dates to 4-digit year format, employ the windowing
technique or replace the equipment. Having implemented these solutions
the systems should be checked with a real time clock (RTC) rollover
test.
Referring to the
embedded and control systems, Mr Sammut said that these were the
hardest systems to track down and audit, and that these systems
affected almost everybody in their every day working and home
life. He gave a whole list of examples - domestic appliances,
traffic light control systems, air traffic control, banking and
financial systems, hospital equipment, power stations, and telecommunications
systems.
So what will happen
at the turn of the century? In many cases the Y2K problem will
result in inconvenience rather than catastrophe but in a few cases
the consequences may be severe or even fatal. Internationally,
Year 2000 work on embedded systems lags behind that of business
systems that is why Action 2000 in the UK considers tackling embedded
systems as a priority.
Mr Sammut ended on
a sombre note with a forecast of the impact on society if the
problem was not tackled professionally - 50% electricity supply
from 1 to 10 January 2000, all forms of transport disrupted for
the whole of January, hospitals on emergency service only for
four weeks, the stock market and banks closed for the first few
days of January, and the postal service in disarray.
