Beginning in 2007, daylight saving time (DST) will be extended in the United States. This results in a new DST period that is four weeks longer than previously observed. Unless certain updates are applied to your computer, it is possible that the time zone settings for your computer's system clock may be incorrect during this four week period. In particular, you must make sure that both your Windows operating system and your calendar programs are updated.
The U.S. Energy Policy Act of 2005, passed by the U.S. Congress July, 2005, extended Daylight Saving Time (DST) in the U.S. by approximately four weeks. As a result, beginning in 2007, DST will start three weeks earlier on March 11, 2007, and end one week later on November 4, 2007, resulting in a new DST period that is four weeks longer than previously observed. These four weeks are referred to in this article as the "extended DST period".
By March 11th, 2007 all systems need to be updated both from an Operating Systems (Windows/Apple) side, as well as each application installed. The effect of this enforcement of an early DST means that all time and/or date stamp functions of a computer will be incorrect by one hour. This will be especially problematic for those students, staff and faculty who rely on Microsoft Outlook or some type of mobile version of Windows for calendaring functionality.
The change in DST will have an effect on many automated and technology reliant products. Individual consumers, small to medium size businesses, and large enterprises may be affected by the new change in time. Computer-system related issues include, for example:
- Calendar / scheduling applications
- Date / time calculations (current and historical)
- Transaction logging (UTC vs. Local Time)
- Tariff billing applications
In many cases, making the necessary changes to accommodate the new DST legislation will be a relatively minor task. Users may need to manually adjust the time on their devices when the change occurs. In other cases, more substantial efforts may be required. In some cases, systems and applications may need to be updated directly, while in others, the application may simply inherit or "read" the date and time information from the underlying system that it resides on so the changes need only be made to that underlying system. Given the broad range of technology in use today-and the integration of systems between customers, vendors, and partners-business and IT managers should determine what actions should be taken to mitigate the affects of DST 2007 on their organizations.
