Daylight Saving Time Changes & Your Computer

In 2005, the United States government passed the Energy Policy Act of 2005, which changes the start and end dates for Daylight Saving Time (DST) as of Spring 2007.

Starting this year, DST will begin on the second Sunday in March (11 March 2007) and end on the first Sunday in November (4 November 2007).

Please review the appropriate sections of this document to ensure that your own system settings have been corrected to reflect the DST change.

Macintosh OS

The 2007 time zone and Daylight Saving Time rule changes for the United States and most of Canada are already available in Mac OS X 10.4.5 (released February 2006) or later.

Apple is also providing software updates for Mac OS X 10.3, 10.4 and later based on worldwide time zone information available as of January 8, 2007.

To make sure that your clock maintains the proper time, simply install the updates that are shown for your computer in Software Update. You should install these updates even if your computer is used in a time zone that is not affected.

For more details about the available updates, or if you have an earlier Mac OS version, see: http://docs.info.apple.com/article.html?artnum=305056

Faculty and Staff:  If your Mac OS version is earlier than 10.3, please contact Kate Etzel.

Java-based Applications

The Java Runtime Environment (JRE) stores rules about DST observance all around the globe. Older JREs have outdated rules that will be superseded by the Energy Policy Act of 2005. As a result, applications running on an older JRE may report incorrect time from March 11, 2007 through April 2, 2007, and from October 29, 2007 through November 4, 2007.

If you are concerned about application failures that may result from these DST changes, you should update your Java Runtime Environment. For more information, see: http://java.sun.com/developer/technicalArticles/Intl/USDST/

Mobile Devices

If you own a brand of PDA that is not covered by this section, we recommend that you check the vendor's website for information about any necessary DST-related updates.


BlackBerry

1. First, determine which software version you have on your BlackBerry:
   
   
   1. On the main page, open Options.
      
      
   2. If you see 2007 DST Patch, you're all set and can ignore the rest of these instructions.  (BlackBerry enterprise users should all be in this category.)
      
      
   3. If you don't see the patch listed, open About. You will see something like this:
      
      BlackBerry [model number]
      Wireless Handheld [carrier id]
      v [version number] Platform [platform number]
      
      
2. If your BlackBerry version number is older than 3.6, your update will come out later.
   
   
3. If your BlackBerry is version 4.x, check to see if your full version number is listed on this web page.
   
   
4. If your full 4.x version number is listed on the web page, follow these steps:
   
   
   1. Close the BlackBerry Desktop Software if it is running on your PC.
   2. Disconnect your BlackBerry Device from your PC. You'll be prompted to reconnect it with the USB cable.
   3. Click here to download the required patch.
      Note: If Internet Explorer or your device stops responding, please view this article.
   4. A reset may be required, and will take 15-20 minutes.
   5. Once the patch is applied, you can view the status of the patch in Options / 2007 DST Patch.
   
   
5. If your version number is not on the web page, your update will come out later.

Palm Pilot & Handspring

Palm devices, both smartphones and handhelds, need to be updated so that they reflect the correct time when the new DST changes take effect. Without the Daylight Saving Time Updates, calendar events and email messages will indicate an hour off the actual time in locations that observe DST. For more information, visit the Palm update site:
