Daylight Savings Time Changes

To: UCSC Faculty, Staff, and Students

From: Information Technology Services (ITS)

Daylight Savings Time will begin three weeks earlier this year on March 11, 2007, and end one week later on November 4, 2007, as a result of the Energy Policy Act passed by Congress in 2005.

This change will impact the way electronic devices, including computers, report the correct time. Operating systems, servers, mobile devices, e-mail, calendaring programs, and office telephones implement Daylight Savings Time in different ways. They may require patches or updates to ensure that the correct time is displayed.

To help the campus prepare for this change, ITS has updated the campus phone, calendar, and e-mail systems to ensure accurate date and time settings. This is happening behind the scenes throughout this week.

Individual workstation operating systems require updates to correctly apply the new DST rules. For Windows XP Pro, Windows Vista, and Mac OS X 10.3/10.4 these updates are downloaded and installed automatically if your workstation is configured for auto-updates. If not, you may need to update your computer. Please refer to this Web site for information on updates and patches that are available for various operating systems, platforms, databases, and mobile devices:
