Changes to Daylight Saving Time in 2007

Background information
A provision of the Energy Policy Act of 2005, extends Daylight Saving Time (DST) by four weeks, beginning in 2007. Systems and applications that process dates and times will be affected by this change.

How do I know if my systems could be affected?
Date and time processing functions in systems and applications in countries implementing the new DST rules (U.S., Canada, Bermuda) are affected. Systems and applications in countries not implementing the DST changes could be affected if they support users, transactions, or applications involving countries that are implementing the new DST rules. For example, scheduling or synchronizing problems may arise where systems make or check date or time stamps relating to transactions in other countries, or there may be difficulty in applications that perform scheduling calculations. Any time-sensitive functions could be impacted by this change.

What do I need to do to protect my systems and applications?
Many systems and applications can be changed now. This site will help you find the necessary information for affected products, so that you can plan updates to help reduce the risk of application and system failure resulting from this change.
