Daylight Savings Time (DST) Patch Info


Overview


On August 8, 2005, President George W. Bush signed the Energy Policy Act of 2005.  This Act extends the transition dates for Daylight Saving Time (DST) in the United States.   Beginning in 2007, DST will now begin three weeks earlier (2:00 A.M. on the second Sunday in March) and will end one week later (2:00 A.M. on the first Sunday in November).  As a result, all operating systems will require an update to reflect the new DST rules. 


CS&T

CS&T has successfully applied the DST patches released for Windows XP and Windows Server 2003, Exchange 2003 SP2, SUN, and VMware systems.  In addition, we have successfully updated the DST parameters on our Windows 2000 systems using the instructions found in KB article 914387 (see below).

Product Update Requirements

Apple OS X
Apple has posted a document on their support site detailing the OS X patches for DST - http://docs.info.apple.com/article.html?artnum=305056

Java

OS X 10.4 (Tiger) Install Java for Mac OS X 10.4, Release 5
OS X 10.3 (Panther) Install Java for Max OS X 10.3, Update 5

BlackBerry
When the DST dates change in March 2007, BlackBerry® devices will not update their clocks for the affected time zones, if no patches for impacted BlackBerry software and third party software are applied. As a result, your BlackBerry devices might not display correct time zone information for certain time periods during the year.

The UCF BlackBerry® Enterprise Server has been patched and is ready for the new Daylight Savings Time changes. All BlackBerry® devices activated on the UCF BES will be upgraded from the BlackBerry® Enterprise Server via a patch deployment utility directly to each device once the patch is tested on our test lab. We will provide information on upgrade dates as soon as we can approve the patch.

Any BlackBerry® devices NOT activated on the UCF BlackBerry® Enterprise Server will need to be upgraded via download the patch from http://www.blackberry.com/select/dst2007/

If you have further questions regarding your BlackBerry® device you can contact Edwin Benitez at 407-823-3941 or ebenitez@mail.ucf.edu.

Microsoft Exchange Server 2007
If you are running Exchange Server 2007, no update is needed.

Microsoft Exchange Server 2003 SP2
A DST Patch for Exchange 2003 SP2 is available on Microsoft’s website via Microsoft Update, the Microsoft Download Center, and through KB article 926666

Microsoft Outlook
A Time Zone Data Update Tool is available to help Outlook users. More information can be found in KB article 931667.

Microsoft Windows Vista
No update needed.  All versions of Windows Vista will ship with updated time zone definitions.

Microsoft Windows XP and 2003
Microsoft released a patch to modify the DST parameters in all Windows XP and 2003 operating systems.  This patch was released in late 2006 and was not considered a critical update.  Please check the optional software updates on Microsoft’s update website to install the patch.

Microsoft Windows 2000
Operating systems running Windows 2000 have passed the end of Mainstream Support by Microsoft and will therefore not receive an update without Extended Hotfix Support.  If you do not have an Extended Hotfix Support Agreement, Microsoft has offered a patch alternative.  Please refer to Microsoft knowledgebase article 914387 for detailed instructions on patching Windows 2000 Systems.      

NetWare
For more information on DST patches for Novell's Netware OS, please go to http://www.novell.com/coolsolutions/feature/18578.html

Novell GroupWise Client
The GroupWise Client depends on the workstation’s operating system for time zone information and as a result, it is not necessary to update GroupWise clients.  Please refer to the ‘GroupWise Clients’ section of Novell document 3802376 for more details.

SUN
Please refer to these articles for information on updating the Operating System and Java Run Time Environment software:
http://java.sun.com/developer/technicalArticles/Intl/USDST.  Please also refer to http://www.sun.com/bigadmin/hubs/dst/ for additional details.

No update needed.  The DST patch has been incorporated into ESX Server versions 2.5.4 build 32233 and later.   If you are running an earlier version of ESX Server, please see VMware article 8695824 for patching details.
