Original document release

Beginning in March 2007, Daylight Saving Time (DST) start and end dates for the United States will transition to comply with the Energy Policy Act of 2005. Under the new law, Daylight Saving Time will begin on the second Sunday of March and end the first Sunday of November, extending the timeframe by four weeks. Previously, Daylight Saving Time began the first Sunday of April and ended on the last Sunday in October. In addition, Canada and Bermuda have made equivalent changes to their Daylight Saving Time rules in an effort to be consistent with U.S. time changes.
Most operating systems that run on ProLiant servers automatically update the system clock at the appropriate time for systems in time zones that observe Daylight Saving Time. However, due to the changes in when Daylight Saving Time takes effect, the system clock will be off by one hour if the operating system is not updated to account for the changes that take place in March of 2007. Operating system and application software vendors are providing updates to correct this situation. HP recommends that customers assess their environment and install the necessary updates on ProLiant servers to adjust for the Daylight Saving Time changes.
For comprehensive information on the Daylight Saving Time changes and HP products and services that may be affected by the Daylight Saving Time changes, visit the HP DST website located at the following URL: http://h10072.www1.hp.com/dst/
Several countries other than United States of America are also implementing the same DST change (Canada, Bermuda), and other countries are expected to make similar changes. For a complete listing of Worldwide Daylight Saving Time schedules, including countries that are changing along with the United States, refer to the Worldwide Daylight Saving reference page, available at the following URL: http://webexhibits.org/daylightsaving/g.html
This Notice answers the following questions and provides detailed information:
Businesses and individuals whose environments are sensitive to date and time transactions and utilize a local time zone may be impacted by changes in the Daylight Saving Time rules. In addition, some applications perform date and time manipulation and may make automatic decisions based on Daylight Saving Time rules. Although this situation should be rare and HP has not identified any particular applications run on x86 servers that make decisions based on Daylight Saving Time, ProLiant customers should be aware of this possibility and take corrective action if they believe they may be affected.
HP recommends customers perform a system assessment to understand what updates may still need to be installed by March 11 to allow for the automated adjustments for the Daylight Saving Time changes to occur.
ARE PROLIANT SERVERS AFFECTED BY THE NEW DST CHANGE?
You are affected by the DST change if:
This is not unique to HP products. All devices that automatically adjust Daylight Saving Time and that support operating systems or software that rely on a local time zone that observes DST will be affected by the 2007 DST change.
WHAT IS HP DOING TO HELP ME UPDATE MY PROLIANT SERVERS?
HP's number one priority is always the satisfaction of its customers. HP is committed to working with its customers to address any potential issues created by the DST change in their HP supported products. HP is providing patches and updates for HP supported products to enable customers to make an effective transition to the DST standards.The information below lists ProLiant software products and how each will be affected by the DST changes. Where applicable, links to patches and operating system updates are provided.
SOFTWARE THAT IS NOT AFFECTED (NO CUSTOMER ACTION NEEDED)
The following HP-specific or HP-supported software is not affected by the DST rules and no customer action is needed:
SOFTWARE THAT REQUIRES AN OPERATING SYSTEM UPDATE
The following HP-specific or HP-supported software utilizes date and time information from the system clock and thus requires an operating system update. These software components do not require a separate update due to the DST rules:
SPECIFIC UPDATES FOR SYSTEMS RUNNING HP SYSTEMS INSIGHT MANAGER (HP SIM)
On systems running HP Systems Insight Manager (HP SIM), in order for the system clock to be accurate when the DST changes take effect, an update to the operating system and then to HP SIM Version 5.1 is required. First update the OS, then update HP SIM to version 5.1, available at the following URL:
http://h18013.www1.hp.com/products/servers/management/hpsim/index.html
SOFTWARE THAT REQUIRES AN OPERATING SYSTEM UPDATE AND AN HP SIM UPDATE
The following HP-Specific or HP-supported software is affected by the DST rules and requires an operating system update and an HP SIM update to version 5.1 (or later) in order for the system clock to be accurate. These software components do not require any additional updates other than updating HP SIM and the operating system:
SOFTWARE THAT REQUIRES AN UPDATE OTHER THAN THE UPDATES DESCRIBED ABOVE
The following HP-specific or HP-supported software is affected by the DST rules and requires an update other than the updates described above:
SOFTWARE THAT WILL BE UPDATED AUTOMATICALLY
The HP Service Essentials Remote Support Software Manager will automatically perform a self-update before March 11, 2007 to patch the version of Java it uses on the CMS.
