Your questions: A few notes on the upcoming “Fall Back” in North America

I had a nice chat yesterday with Michelle Kessler of USA TODAY, discussing the impact of the extension to DST this year.



“Some Americans are finding themselves behind the times thanks to a daylight saving shift that is confusing people and electronics. Daylight saving used to end on the last weekend in October. But Congress changed it to the first weekend in November this year in an effort to save power.


“That may save electricity, but it’s causing a brain drain as the country figures out what time it is. Creating confusion: Some PCs, cellphones and other electronics are still programmed to “fall back” on the old date, which was Sunday. Thousands of people in New York, Chicago, San Francisco and elsewhere have called city information lines just to ask what time it is.”


I noted in the discussion that a large number of people downloaded the update, via our website but primarily through Automatic Updates.  But there are a few instances where devices need to be more closely managed, such as products covered by mobile operators.  Some phones have been updated via over the air (aka OTA) updates.


Keep in mind that the upcoming change to DST in the States and Canada aren’t a single change, but one of a myriad of changes that have happened throughout this year.  Much like changes to the computer, we recommend that our customers make a concerted effort to keep their products up to date.


Michelle asked…



“So, if you have [Windows] Automatic Update you are fine, but if it’s turned off then you may need to [manually] update?”


Generally, that’s right. Of course, your individual case may require more attention.  For support, turn on Automatic Updates, visit Windows Update for the latest, or go to http://www.microsoft.com/time for info about Microsoft applications and services.  That will take you to the Microsoft central support site, where you can navigate to more information on products that require updates or attention.  And it’s not just about Microsoft products but many others in the ecosystem, so should contact software and hardware vendors for updates.



“Is it fair to assume that it’s because people addressed in the spring?”


I think so, as people paid attention to DST changes in the spring, and realized that it’s not just a domestic issue, but a worldwide impact with all the changes internationally (many are referenced on my blog). 


More info: see Rich’s article on Microsoft PressPass, as he discusses the second part of the Daylight Saving Time extension to come in North America, lessons learned from March’s “spring forward,” and the effects these changes have on customers around the world.

Make sure you “Fall Back” next week: Windows Mobile and Daylight Saving Time

Yesterday, October 28th, would have been the timeframe for the US Daylight Savings Time changeover under prior rules.  The new rules call for the US and Canadian DST “Fall Back” to occur in the early morning of Sunday, November 4. 

A recent update was posted to our DST & TZ hot topics page which details impacts to some users of certain Windows Mobile devices, who experienced an early changeover.   A copy of that posting is found below – please refer to the information on the page and contact your mobile operator’s customer support line if you experience any difficulties. 

Windows Mobile Devices

In observance of the various Daylight Saving Time (DST) and time zone changes, Microsoft has been working closely with customers, partners and others in the industry to help ensure a smooth and seamless transition.  Although updates have been made available for mobile devices running Windows Mobile software, some end users may not have the information needed or followed the steps necessary to apply those patches.  The correct end to DST for 2007 in North America is November 4th. 

Mobile devices for users who did not update may have experienced the “Fall Back” in North America on October 28th, as some user’s mobile devices and their calendars may be incorrectly early by one hour for the following week if the appropriate updates are not applied. Microsoft recommendations that those customers needing to update should follow the instructions on http://www.microsoft.com/windowsmobile/daylightsaving/default.mspx for updating their devices.

Generally it seems that some new devices may not have the latest update for the 2007 DST and TZ rules.  My wife has a Cingular (now AT&T) 8525 Pocket PC Phone that she received late this summer as a replacement for a unit still under warranty, and the phone came loaded with the fix already installed.

For the latest news and customer guidance, please visit Microsoft’s Hot Topics web page at http://www.microsoft.com/time.

Windows Hotfix Update now available for new Daylight Saving Time changes in Brazil

To be posted the Microsoft Daylight Saving Time & Time Zone Hot Topics page at http://support.microsoft.com/gp/dst_hottopics

Brazil 2007-2008 Daylight Saving changes: The government of Brazil announced a change on September 20, 2007, in the observance of daylight saving time in the country. The new time change will take place in Brazil on October 14th (three weeks earlier than in 2006) when clocks should move one hour forward at midnight (between Saturday and Sunday). On February 17, 2008, Brazil will move clocks one hour at midnight (again, between Saturday and Sunday), one week earlier than in 2006.

Microsoft has provided a hotfix update for customers requiring an update for this time change: for more information and to obtain the hotfix, please see Microsoft Knowledge Base article 943000.

Manual remediation has been provided for Windows as noted in KB article 914387, updated with the proper registry keys to account for the changes in Brazil; “Dynamic DST” keys are included allowing calendar rebasing with the Outlook Time Zone Data Update Tool (TZDUT).

Your questions: Is DST changing in Victoria, Australia?

A question from the Technical Deep-Dive LiveMeeting today on DST and Time Zones today…

“I believe Victoria, Australia will be extending daylight savings by a week (ending April 6, 2008 instead of end of March ’08) is this covered [in the latest Windows OS update, KB 933360]?”

No, not currently as this has not yet been passed into law. It was reported today that the daylight saving legislation will be introduced this week in Australia and propose that daylight saving be in sync across NSW, the ACT, Victoria and South Australia. More as it develops.

For our webcast, thanks today to Alon, Sophia, Beth, Joel, David, Bob, Gil, Jim and Steve, as well as our LM hostess, Tania.

As mentioned previously, later this year we expect to release the 2008 Cumulative Time Zone Update for Windows that will set the known, correct dates for 2008 (it should include changes for Brazil and any other country that changes the observance of DST entry/exit dates in 2008). Our goal is to move to a regular cadence, releasing cumulative time zone updates for Windows. We are checking on the ability to include Venezuela as well in this update.

For those in government considering changing the observance of DST or Summer Time in your country: figure on at least a year (perhaps even two) to ensure that not only vendors but those IT professionals impacted by the changes have enough time to make the appropriate decisions.
