Daylight Saving Time Changes

Addendum 2007-03-19

Regarding the recent Daylight Saving Time changes as mandated by the government, the University of Evansville is following the same deployment guides as the rest of the world. As such, we are feeling the same pain caused by the Daylight Saving Time change. As mentioned in a recent Technology Services Announcement, OST is still working on an acceptable solution to this issue.

While an acceptable solution is being developed, OTS can offer a small piece of assistance we are testing. Microsoft has released an application to assist in re-assigning time to calendar entries. The following steps may help you correct dates and times, in your Exchange mailbox.

1. Go to UEcommon\Everyone\DST Updates and double click on the application “tzmove.exe”. This will launch and install an Outlook utility that will bulk-change your calendar entries.
2. After accepting the license agreement, you will be shown a screen showing the Outlook profiles configured on your machine. Make sure your profile is selected (denoted by your name beside the mailbox), and click OK.
3. The application will then tell you how many affected calendar entries it finds. Click the details button to display the list of entries. From the list, if the new time shown is correct, leave the entry checked. If the new time shown is not correct, uncheck the entry. You can then click OK, and it will bulk change the times for those entries chosen.

Overview

Starting in 2007, Daylight Saving Time (DST) begins each year at 2:00 a.m. (local time) on the second Sunday in March in most of the United States and its territories. Clocks must be moved ahead one hour when DST goes into effect. DST is not observed in Hawaii, American Samoa, Guam, Puerto Rico, the Virgin Islands and the state of Arizona (with the exception of the Navajo Indian Reservation, which does observe DST).

Standard Time begins each year at 2:00 a.m. (local time) on the first Sunday of November. Move your clocks back one hour at the resumption of Standard Time.

• In 2007, DST begins at 2:00 a.m. (local time) on March 11, 2007.
• In 2007, DST ends at 2:00 a.m. (local time) on November 4, 2007.

The current Daylight Saving Time rules represent a change from the past. On August 8, 2005, President Bush signed the Energy Policy Act of 2005, which included the changes in Daylight Saving Time described above, effective March 1, 2007. Prior to 2007, DST began at 2:00 a.m. (local time) on the first Sunday in April, and ended at 2:00 a.m. (local time) on the last Sunday in October. The new rules for DST beginning in 2007 mean an extra four or five weeks of DST each year. There will now be a total of 238 days of DST, compared to a total of 210 days of DST in 2006 under the previous rules. Daylight Saving Time and time zones are regulated by the U. S. Department of Transportation, and not by NIST.

NIST radio broadcasts from station WWVB automatically synchronize many millions of consumer electronic products to NIST time, including wall clocks, watches, clock radios, and other timekeeping devices. These NIST radio broadcast includes information on whether or not DST is in effect, so these timekeeping products automatically correct for DST at the proper day and time. For more information, see the NIST web page on radio controlled clocks.

How Does This Affect UE and Me?

All UE-owned computers and systems require an update that will correctly set the DST according to the changes made by the government. Affected computers include Windows PCs and Macs. Affected systems include Datatel and the Exchange mail servers.

On Sunday, February 25, 2007, the Office of Technology Services will update all Windows PCs, Mac and the Exchange mail servers.

The Office of Technology Services will not apply this update to your home or personal computer.

• If you own a Windows PC, you can download a patch from Microsoft.
• If you own a Mac, you can learn more about updating your Mac for the DST changes.

What Do I Need To Do?

If you do not use the calendar in Exchange/Outlook, you do not need to do anything regarding the DST changes. If you use Exchange/Outlook to schedule meetings or appointments, please continue reading.

Prior to February 25, 2007, it is highly-recommended that you print a copy, for reference, of your Exchange/Outlook calendar. You will only need to print the calendar items for the three-week period between March 11, 2007 and April 1, 2007 and the week of October 28, 2007 and November 4, 2007.

Since OTS will need to "push" an update to your computer, please make sure that you do not shut down your computer before February 25, 2007. The computers need to be powered-on to receive the update. You should, however, save all files and log off, not shut-down, the computer.

After to February 25, 2007, you will need to ensure your calendar's existing meetings and appointments are correct. You will only need to do this once. After February 25, 2007, the Exchange mail server will correctly handle normal DST changes.
