Microsoft Office Outlook Tool: Time Zone Data Update Tool for Microsoft Office Outlook

At last!  This slipped out over night.  All we need now is the Exchange version. Source:

In order to address time zone changes, this tool will help adjust calendar items in Outlook after the operating system has been updated with new time zone definitions. While this tool is being released in advance of the U.S. Daylight saving time rules change in 2007, it can be used for general adjustments of calendar items based on changes in time zone definitions saved in Windows or by the user making a permanent move to another time zone.


  • In existing recurring appointments, Outlook has encoded the current DST rules: Instances of recurring appointments that occur during the delta period will appear one hour earlier than they should.
  • For existing single-instance appointments and reminders, Outlook already calculated the universal time coordinate (UTC) value upon appointment creation: If a user creates an appointment while Windows is configured for the old DST rules and the appointment itself occurs during the “new” DST weeks, the appointment will appear one hour earlier than it should.
  • Existing all-day events are associated with 24 specific hours instead of a given date: For the reasons described above, all-day events will appear to shift and thus span two days during the “new” DST weeks.

DST 2007

Okay some more information for you.  Interesting how this coule be a one off as “Congress retains the right to resume the 2005 Daylight Saving Time schedule once the Department of Energy study is complete”

UPDATE #1: Just found this too. it would seem that TWO calendar update tool are going to be avaialble.  It looks like the Outlook Tool will run against a user, so I suspect the Exchange Tool will just do a batch conversion for ALL the users on a server.  One for users and one for administrators to run. To modify a users mailbox, the Exchange Tool is going to need “god” access to all the mailboxes, so you will need an account setup with the right permissions. What will be interesting is how the tool works?  Will it just update the meeting request or will it update and then send out a change to all the attendees?  If it does the later and you batch the messages on the server, make sure you have enough log disk space and you do it out of hours.  We will have to wait and see what the tool does. Check out:  Right down the bottom. Q: How does the Exchange tool compare to the Time Zone Data Update Tool?
A: The Exchange tool will allow you to apply the time zone update in ‘silent mode’ to a set of chosen mailboxes on the Exchange server. This will mean the user will not have a chance to uncheck appointments that do not need updating.
The Exchange tool only works on server-side calendars. This means that any local Calendars that a user might have, such as in PST stores, can only be updated by the client-side Time Zone Data Update Tool.

and in under “Steps you need to take” #4 Run the Time Zone Data Update Tool to update Outlook calendars that are saved on servers running Exchange and on individual computers. End users use the Time Zone Data Update Tool. IT administrators use the Exchange version of the update tool.



Rationales for DST: One of the major reasons given for observing DST is energy conservation. Theoretically, the amount of residential electricity needed in evening hours is dependent both on when the sun sets and when people go to bed. Because people tend to observe the same bedtime year-round, by artificially moving sunset one hour later, the amount of energy used is theoretically reduced. A 1975 United States Department of Transportation study showed that DST would theoretically reduce the country’s electricity usage by 1% from March to April, if implemented during these months. These numbers have been supported in Mexico, which began implementing daylight saving time in 1996. Evaluations show national savings of 0.7% of national electric consumption (1.3 billion kWh (TWh)) and reduction of peak load by 500 MW.

Part of the reason that it is normally observed only in the early spring, summer, and early autumn instead of the winter months is that the amount of energy saved by experiencing sunset one hour later would be negated by the increased need for artificial morning lighting due to a later sunrise. During the summer most people would wake up after the sun rises, regardless of whether daylight saving time is in effect or not, so there is no increased need for morning lighting to offset the afternoon drop in energy usage. Another reason for not observing daylight saving time in the winter is concern about children walking to school in the dark.

Another argued benefit of DST is increased opportunities for outdoor activities. Most people plan outdoor activities during sunlight hours. Other benefits cited include prevention of traffic injuries (by allowing more people to return home from work or school in daylight), and crime reduction (by reducing people’s risk of being targets of crimes that are more common in dark areas).

When the U.S. went on extended DST in 1974 and 1975 in response to the 1973 energy crisis, Department of Transportation studies found that observing DST in March and April saved 10,000 barrels of oil a day, and prevented about 2,000 traffic injuries and 50 fatalities saving about U.S. $28 million in traffic costs.

DST 2007 changes for US, Canada and Bermuda
This information applies to users in the areas of the United States and Canada that observe daylight saving time.

For the latest information on DST 2007 check out:

On August 8, 2005, President George W. Bush signed the Energy Policy Act of 2005. This Act changed the time change dates for Daylight Saving Time in the U.S. Beginning in 2007, DST will begin on the second Sunday in March and end the first Sunday in November. The Secretary of Energy will report the impact of this change to Congress.
Congress retains the right to resume the 2005 Daylight Saving Time schedule once the Department of Energy study is complete.

Canada and Bermuda made similar changes to their DST rules to be consistent with the U.S. time changes.
The 2007 daylight saving time implementation is as follows:
Clocks change at 02:00 A.M. local time.

On March 11, 2007, clocks will move forward one hour from 01:59 A.M. to 03:00 A.M. On November 4, 2007, clocks will move back one hour from 01:59 A.M. to 01:00 A.M.

This change affects the following time zones:

GMT-3:30 Newfoundland
GMT-4 Atlantic
GMT-5 Eastern US
GMT-6 Central US
GMT-7 Mountain US
GMT-8 Pacific US
GMT-9 Alaska

How do DST changes affect I
T systems worldwide?


Date and time processing functions in systems and applications in countries implementing the new DST rules (U.S., Canada, Bermuda) are affected. Systems and applications in countries not implementing the DST changes could be affected if they support users, transactions, or applications involving countries that are implementing the new DST rules. For example, scheduling or synchronizing problems may arise where systems make or check date or time stamps relating to transactions in other countries, or there may be difficulty in applications that perform scheduling calculations. Any time-sensitive functions could be impacted by this change.

DST rules affect date and time processing functions in computers and applications. If not set properly, depending upon how uniformly updates are applied, the time could be incorrect by one hour for four weeks each year.

More DST 2007

This is turning into a REALLY REALLY BIG issue. 

To be clear the new DST change periods are: March 11, 2007 to April 1, 2007 and from October 28, 2007 to November 4, 2007.

New DST Start

March 11, 2007
(three weeks earlier)

Previous DST Start

April 1, 2007

Previous DST End

October 28, 2007

New DST End

November 4, 2007
(one week later)

 So Microsoft Articles to date are:

Blackberry Articles: US Daylight Saving Time Changes and Blackberry

IBM Articles: Lotus software- Daylight Saving Time (DST) changes for 2007 will affect Lotus software products

Also remember that any other Application that uses CDO will need to be updated.  Check with your Application vendor first.

Outlook is looking like it’s going to be a pain in the butt.  The problem is that when you apply the Windows Operating System Update for DST 2007 you will have Outlook calendar appointments off by 1 hour during the DST Change periods.

The solution requires three things to be in place for Outlook calendar items to be updated properly.

  1. The Operating System update to change the time zone information.  928388 or 914387 (available now).
  2. The Exchange Server 2003 Update for CDO.  926666 (available now).
  3. The Outlook Time Zone Data update Tool and the Exchange Time Zone Update Tool. (not released yet).

If all of these patches and tools are not used together, then there will be calendar inconsistencies.  If you install update 928388 or 914387 for the operating system without doing anything else, users are notice that the meetings during the DST change periods are ahead by 1 hour.  This is expected behavior without installing the Exchange server hotfix 926666 patch and using the Outlook or Exchange tool to rebase the appointments that are in the DST change period. 

The Outlook tool is due to be released in January 2007 through the Microsoft Download Center that can update calendar items in Outlook to accommodate the changes in DST during the Extended DST period. This program is called the Time Zone Data Update Tool for Microsoft® Office Outlook® (Time Zone Data Update Tool).
Microsoft Office Outlook 2007, the newest version of Outlook, has the ability to automatically detect the DST change and prompt the process that updates a person’s calendar to conform to the new daylight saving time rules. However, the Time Zone Data Update Tool contains enhancements that improve upon what is available in Outlook 2007and should be run instead of the out-of-the-box Outlook 2007 experience.

The Time Zone Data Update Tool is necessary to update calendar items that occur during the Extended DST periods for the following earlier versions of Microsoft Outlook:

  • Microsoft Office Outlook 2003
  • Microsoft Outlook 2002
  • Microsoft Outlook 2000

The following table describes the situations when you should download and run the Time Zone Data Update Tool:


Outlook 2007 Outlook 2003, Outlook 2002, Outlook 2000
Not required to use the Time Zone Data Update Tool. But it is highly recommended because it includes numerous improvements. Run the Time Zone Data Update Tool.
In environments running Microsoft Exchange, a special version of the Time Zone Data Update Tool may be used to update multiple Exchange mailboxes on the server. In environments running Microsoft Exchange, a special version of the Time Zone Data Update Tool may be used to update multiple Exchange mailboxes on the server.
