Is your company Daylight Savings Time compliant?

Computer firms are alerting their customers of an impending problem related to the change in daylight savings time next month, which could throw computer clocks off by an hour.

The issue stems from the change in dates for daylight savings time. Beginning this year, DST begins on the second Sunday of March instead of the first Sunday in April, and ends on the first Sunday in November instead of the last Sunday of October.

In 2005, Congress passed and President Bush signed into law the Energy Policy Act, which amended the Uniform Time Act of 1966 to change the beginning and ending of Daylight Saving Time (DST).

The impact on hardware and software is that daylight savings time changes are programmed into their internal clocks, and systems developed before the 2005 law have the wrong dates in them. Therefore, old hardware and operating systems are still operating on the April/October date change rather than March/November.

This is a fix anyone can make. All a person needs to do is apply the patches from the vendors, or at worst alter their system clock manually. Still, research firm Gartner has sent out an advisory to its clients not to downplay the risk.

"Few IT organizations have any formalized risk assessment and remediation program in place to address the potential impact of this time modification," the research firm wrote.

There is the real risk of business damage, and liabilities could occur from applications performing their processing at the incorrect time. "Because code changes will usually not be required and most applications take their time from the underlying operating system (and hence only this needs to be patched), the overall remediation effort will pale in comparison to that of Y2K," the Gartner report concludes.
