It’s Time To Fall Back An Hour in the US and Canada: Daylight Saving Time Ends This Sunday

Microsoft Office Clip ArtYes, it’s that time again if you’ll pardon the pun, to fall back in much of the Northern Hemisphere.

Daylight saving time ends at 2:00AM local time on Sunday, November 7, 2010, in much of the U.S and Canada, except in parts of the countries (including Hawaii and Arizona). You can read more than you’ll ever want to know about DST here and on our official Microsoft Daylight Saving Time Help and Support Center at http://www.microsoft.com/time.

This year, DST in much of the US and Canada ends in accordance with the US Department of Energy’s Energy Policy Act of 2005 that was passed into law. DST will end later than it did prior to 2007, on the first Sunday of November (in 2010, November 7); more details on the new DST start and end times can be found here). This results in a new DST period that is approximately three to four weeks longer than in previous years.

The switch to daylight saving time also means the time zone suffix changes, now using Daylight Time: for example, Pacific Standard Time is now Pacific Daylight Time (aka PDT). The other time zones move to Mountain Daylight Time (MDT), Central Daylight Time (CDT), and Eastern Daylight Time (EDT).

As I noted in this article, Microsoft strongly recommends that DST and time zone updates be installed on all affected systems, devices and applications to ensure consistency with current DST rules and time zone settings worldwide. Customers should review the product updates available and posted on this site and at http://support.microsoft.com/gp/dst_prodlist for the latest and updated information of Microsoft products affected by daylight saving time.

Fox News offers this commentary on DST, for your viewing pleasure.

It’s Time To Spring Forward An Hour in the US and Canada: Daylight Saving Time Arrives Sunday

Microsoft Office Clip ArtOMG… what time is it? what time is it? I have a webcast to do… Beth? Paul? Rich? Where’s the post on the updates? 


Oh, sorry… flashback to 2007.


I’m reminded that next time you’ll change your clocks for daylight saving time (aka DST) is this Sunday, March 14, 2010, as we will Spring Forward in much of the States and Canada on Sunday at 2:00AM, as noted in more than 3,100 news articles today.


I can imagine that a few people at SXSW and Mix10 will remember.


This year, DST in much of the US and Canada begins on March 14, several weeks earlier than in years prior to 2007. In 2007, most of the US and Canada “sprang forward” a few weeks earlier than in past years in accordance with the US Department of Energy’s Energy Policy Act of 2005 that was passed into law. DST will end later than it did prior to 2007, on the first Sunday of November (in 2010, November 7); more details on the new DST start and end times can be found here). This results in a new DST period that is approximately three to four weeks longer than in previous years.


The switch to daylight saving time also means the time zone suffix changes, now using Daylight Time: for example, Pacific Standard Time is now Pacific Daylight Time (aka PDT). The other time zones move to Mountain Daylight Time (MDT), Central Daylight Time (CDT), and Eastern Daylight Time (EDT).


By the way, when I say , I mean “”, there are a few exeptions to the DST rules. Jason Foster – The Herald notes in his piece



“Hawaii and Arizona are the only two U.S. states that don’t observe daylight saving time. The Navajo Indian Reservation in Arizona does observe daylight saving time. The part of Indiana that falls in the Eastern Time Zone also does not follow DST.”


Hawaii not on DST I understand – it’s off teh grid and who wants to worry about changing their watches on vacation? (Seriously, it does mess with small details like television programming and flight schedules from the mainland.) Arizona? Something to do with the weather, as


Chris Kline covered for  the ABC affiliate in his article “Weird? Why Arizona doesn’t observe Daylight Saving Time



“The history of daylight saving is tied to energy conservation. Switching to DST in the summer means more sunlight at night, which in turn means homes don’t have to turn on lights as early. According to the U.S. Government, that leads to energy and fuel savings.”


And Indiana. Ah, yes… Indiana. You’ll find everything you need to know about this in articles like this one for Indiana. Salon notes in their article Please end Daylight Saving Time



“In fact, farmers generally oppose daylight saving time. In Indiana, where part of the state observes DST and part does not, farmers have opposed a move to DST.”


As noted in the Examiner, Summer Time begins and ends for the European Union at 1:00AM Universal Time (aka Greenwich Mean Time). “The Europeans turn their clock forward on the third Sunday in March and ends the last Sunday in October. In the EU, all time zones change at the same moment.”



What to do


So what should you do to make sure that your computers are ready for the change?  If you use Microsoft Update on your PC at home, chances are you’re already covered.  The December Cumulative Daylight Saving Time and Time Zone Update for Windows should already be installed on your PC.  If you’re not sure, visit Microsoft Windows Update to check your PC and install important updates.  At work, if an IT Pro (aka ‘hero’) manages your network, chances are good that the needed updates have already been installed on your computers and devices automagically.


Recently, I received a question similar to one I answered last year on daylight saving time and time zone updates to Windows:



“We updated our systems earlier this year for daylight saving time [the rules for the US and Canada].  Is there anything we need to do?  Should we also update our systems with the last DST update?”


Generally, the answer is yes.  As I noted earlier here, it depends.


If you manage servers and a host of Microsoft software, visit http://www.microsoft.com/time for more details.  And visit the support web sites of any other software companies to see if you need to apply any updates – it’s not just Microsoft software that may require updates.  Keep in mind that it’s not just the US and Canada that made changes to DST and time zones: we have an upcoming change in Australia and others noted on the DST and Time Zone Hot Topics page.


And remember: time is a precious thing. Never waste it.
