Daylight Saving Time Issues at NC State

Recommendations for Calendar Users:

We strongly recommend that users of calendaring applications include the scheduled time in meeting titles for all events occurring during the 4-weeks of extended Daylight Saving Time (DST), 3/11-4/1/2007 and 10/28-11/4/2007. Meetings occurring during the extended DST time period may appear at the incorrect time under certain circumstances. For details and recommendations, please review DST information about Oracle Calendar solutions or ETSS Novell Groupwise.

This web site will provide information on patches, known problems and ways to fix or mitigate the problems. Please send any questions concerning DST issues to help@ncsu.edu .

Expansion of Daylight Saving Time

Daylight Saving Time (DST) is being extended by 4 weeks starting this year. It starts 3 weeks earlier and ends one week later under provisions of the U.S. Energy Policy Act of 2005. This is the first nationwide change to the DST schedule in approximately 20 years. The new and former DST dates for 2007 follow:

DST Begins (advance 1 hour): Sun., 3/11/2007, 2 a.m. (formerly 4/1/2007)
DST Ends (back 1 hour): Sunday, 11/4/2007, 2 a.m. (formerly 10/28/2007)

All computers and time-dependent systems which have been designed to automatically adjust for DST must be patched to properly reflect the changes in Daylight Saving Time effective in 2007. Patching is typically done at the Operating System (OS) level and is essential to do since many applications rely on time/date accuracy.

Calendaring systems are already being adversely impacted by the 4-week expansion of Day light Saving Time (DST) this year. Users of group calendaring systems, including Oracle Calendar, as well as standalone calendaring software such as Microsoft Outlook, should take steps to ease the transition as soon as possible.

All Oracle Calendar account holders were sent email with additional details regarding DST changes on Friday, 2 February 2007.
