Check with your Local Support Provider (LSP) regarding recommendations and plans for patching the applications and systems in use within your department or office.Make sure that under TimeZone Support the same settings are used as you found at step A. Many newer electronic devices (computers, PDAs, cell phones, etc.) and recent versions of software will handle the change automatically however, older devices and software programmed to gain or lose an hour according to the traditional DST schedule will need to be вЂњpatchedвЂќ or have the time adjusted manually on the new DST dates. This yearвЂ™s actual start date is Sunday, March 11, 2007, at 2 a.m., and the end date is Sunday, November 4, 2007, at 2 a.m. DST will start on the second Sunday in March, three weeks earlier than previously, and end on the first Sunday in November, one week later than previously. Some countries may not observe daylight saving time (DST), whereas other countries may change the start dates and end dates for daylight saving time Beginning this year, Daylight Saving Time (DST) will be in effect for four extra weeks, as mandated in the 2005 Energy Policy Act. Daylight saving time implementation varies from country to country.

Systems running OS 10.3.9 through 10.4.5 will also change to and from DST on the new dates automatically, provided they have been вЂњpatchedвЂќ recently using AppleвЂ™s Software Update Service. For instructions on adjusting your computerвЂ™s clock, please see the information at Mac OS desktops and laptops: Systems running Mac OS 10.4.6 and later will change to and from DST on the new dates automatically. However, on systems running older versions of Windows, the time will need to be adjusted manually on the new DST dates. New Windows Vista systems will also change time automatically on the new dates. Most University-owned Windows systems fall into this category.

To be safe, all repeat meetings/appointments as well as those scheduled for the date ranges above should be considered suspect until confirmed via email with all meeting participants. Users who synchronize their calendar between two or more devices may also see inconsistencies. Repeat meetings scheduled throughout the year may also be problematic. Please see for details.Calendaring Software: Users of calendaring software such as Meeting Maker and Microsoft Office Outlook/Exchange need to pay special attention to meetings scheduled between March 11 and April 1 and those scheduled between October 28 and November 4, when some participantsвЂ™ calendars may be out of synch. Some vendors are providing operating system patches that users can install and others are requiring manual updates. To change the time, go to the System Preferences for Date & Time, accessible from the Apple menu, reset the time and be sure to deselect the option to set date and time automatically.Mobile devices: The system clocks of PDAs, smartphones, and other mobile devices also need to be adjusted for the new DST rules.

Microsoft Office Outlook 2007 handles the new DST dates correctly. To be safe, Meeting Maker users should heed the general advice in the previous paragraph. However, meetings that are proposed or accepted across certain time zones (Arizona, Indiana, and international time zones), for example, by traveling faculty and staff, may show incorrectly, as may repeat meetings that occur during the DST period and beyond. The version of Meeting Maker calendar software currently used at Penn will work correctly for meetings that are proposed and accepted within the same time zone.
