Beginning this year, the start and end dates for Daylight Saving Time (DST) for the U.S. will change to comply with the Energy Policy Act of 2005, as well as parts of other countries such as Canada, Mexico, and Bermuda.
Under the new law, DST will begin the second Sunday of March and end the first Sunday of November, extending DST by four weeks.
The objective is to move an hour of daylight from the morning to the evening to provide more natural light in the evening hours when energy consumption and the demand for lighting is at its highest.
HP and non-HP computing devices that adjust DST automatically, support operating systems or rely on local time zones that observe DST could be affected by the DST change.
For example, you may be affected if you run a computer system in the U.S., Canada or Bermuda particularly if the system runs applications that perform time-sensitive functions, such as scheduling or validating time or date stamps. You may also be affected if your systems interact or integrate with systems that have transitioned to the new DST change.
In these cases, operating system and application software updates may be required to ensure that the system clocks on your HP products are accurate.
The latest information on the impact to HP supported products can be found at http://www.hp.com/go/DST. Use this information to perform an assessment of your HP products to determine if you need to install the updates as a result of the DST change or if they already reside on your systems. Check this website regularly for the most up-to-date information.
If you determine that operating system and application software updates are required, visit http://www.hp.com/go/DST for the patches, updates or workarounds you need for affected HP products.
HP is also actively working with our third-party vendors to understand whether they need to make changes to their products to support the new DST rules. Contact your third party vendor for the latest status.
If you choose to take no action, you increase the risk that your systems will not perform time-sensitive functions correctly. This could result in applications not launching at the expected time or invalid date stamps.
Based on your particular configuration and applications, you may encounter a DST issue that HP or your third-party software vendor has not addressed. In that case, use your normal process for problem reporting to HP and/or refer to the DST web page for information on product support.
