Windows Mobile My Phone (no, it’s not “MyPhone”) beta site debuts. Sign up soon available soon?

I just saw that the new Microsoft Windows Mobile "My Phone" site (or is it myPhone? 😉 went live…

My Phone"Coming soon… Microsoft My Phone syncs information between your mobile phone and the web, enabling you to:

  • Back up and restore your phone’s information to a password-protected web site
  • Access and update your contacts and appointments through your web account
  • Share photos on your phone with family and friends"

You can find out more here, but no word yet that I’ve seen publicly on when you can register for the beta.

Should be interesting.  With 200 MB of free storage available on the Microsoft My Phone web site, I wonder if you’ll be able to tap into LiveMesh and online storage via SkyDrive. If a phone synchronization results in exceeding the My Phone limit, it would be handy to enable "overdraft protection" on SkyDrive.

Advisory: Information on daylight saving time changes for Mauritius and Egypt in 2008

Coming soon to our Hot Topics for Daylight Saving Time changes page, information on changes accommodating Mauritius and Egypt.

Guidance for Mauritius on Upcoming Daylight Saving Time Implementation for 2008-2009

As noted at on July 23, 2008 and in L’Express newspaper, the government of Mauritius has decided to adopt Summer Time (as it’s known in Europe, aka daylight saving time) in the island nation of over 1 million.   According to published government announcements, the country will begin recognizing Summer Time in October of this year. Official reports note that DST will begin on October 26, 2008 and end on March 27, 2009.

The post on our Technet blog summarizes the actions recommended for customers in Mauritius to address the implementation of daylight saving time and mitigate its impacts. These are the impacts primarily anticipated at the time this document was written, and the effects that customers may face are not restricted to them.

Windows Hotfix Available for Egypt 2008 Daylight Savings Time Change

The government of Egypt announced that due to the observance of Ramadan,  it has changed the end of Daylight Savings Time to August 28, 2008 at midnight.  

Microsoft has created upon request, out of band release packages for Windows Vista, Windows Server 2008, Windows XP and Windows Server 2003 for the Egypt  DST update, Knowledge Base Article 953732, “A hotfix is available to update the ” (GMT+02:00) Cairo” time zone for 2008 in Windows XP, Windows Server 2003, Windows Vista and Windows Server 2008.” Click here to view and request hotfix downloads.

Please note that these packages are call-in/request only packages and will not be released to the Microsoft Download Center or via Microsoft Update Services.  This change will be included in the next DST Windows cumulative package released for all currently supported operating systems in December 2008 (Windows XP, Windows Server 2003, Windows Server 2008 and Windows Vista).

What time is it Down Under? Daylight Saving Time comes to much of Australia on October 5

A quick quick Tweet as the Register’s James Sherwood reports that the Daylight savings shift to cause phone havoc Down Under (that’s Australia…):

“Unsuspecting Aussies could be in for a spot of time travel this weekend, because Australian network operator Telstra has warned that some Down Under phones won’t support the country’s upcoming daylight savings time adjustment.”

Well, if you read this blog and visit our sites, you’re likely prepared for this change.

As noted here, on October 5th, much of Australia — Eastern (New South Wales, Victoria, Australian Capital Territory and Tasmania) and Central (South Australia) time zones — will begin daylight saving time. The Australia Eastern & Central 2008 Daylight Saving Changes page and the official Australian Government Time web site provide more information to prepare and educate end users and businesses on the changes in Australia. 

Daylight Saving Time is observed in New South Wales, Victoria, South Australia, Tasmania, and the Australian Capital Territory and has been synchronised across these states. Western Australia began a three year trial of daylight saving on 3 December 2006. Queensland and the Northern Territory do not observe daylight saving.

Across the south-eastern states and the ACT, daylight saving for future summers begins at 2am Eastern Standard Time on the first Sunday in October and ends at 2am Eastern Standard Time (3am summer time) on the first Sunday in April.

So, what do you need to do?  Nothing, most likely if you have installed the cumulative update for Windows OS in December 2007 from late last year (or the latest cumulative update from August 2008) – these updates include the revisions for…

Central Australia Standard Time
Australia Eastern Standard Time
Tasmania Standard Time
Adjusts DST start times and end times for these time zones so that they start and end on the same day. This was changed after the prior cumulative time zone update was created (August 2007).

Such changes can have a significant impact on business performance if not dealt with proactively.  As we note on the Australian site above, impacts can range from the incorrect time displayed on a clock to calendaring problems. For IT Pros and SysAdmins, we recommend that you review the Australia 2008 Daylight Saving Planning Guide, which provides detailed guidance on preparing Microsoft solutions in complex environments for changes in daylight saving.  You can click on the links below to download the document in your preferred format:

Announcement: Coming in December: Microsoft Updates to Daylight Saving Time and Time Zones

Clip art from Office Online First off, I want to welcome Lourdes to the DST blog over at  She is coordinating the efforts on our daylight saving time and time zone updates and releases for current products across the various product groups at Microsoft.  A tough job, to say the least.  She will also help coordinate messaging and communications with many other folks you may remember across our product groups, field sales and technical account teams, customer support and execs.  It’s great to have her on board.

I wanted to provide some insight as to the effort we just kicked off the planning for our December 2008 cumulative time zone update for Microsoft Windows operating systems and other products. (You may recall that the Windows Sustained Engineering team completed and released KB 951072, the August 2008 cumulative time zone update for Microsoft Windows operating systems.)  I also posted this to Twitter as it appears on my various social networking updates – we’ll see how effective these updates are for folks.

As we update the Microsoft daylight saving time and time zone help and support pages at, I expect that other product teams at Microsoft will also provide information on their products and publish the associated documentation (KBs, blog posts) in the November and early December time frame.  Groups will note any changes and updates in their documentation, products and services, and guidance for their support teams and the field.

So, back to the December 2008 release.

Coming soon are updates to the list of Microsoft products affected by DST and time zone changes.  We also have a number of new update notices on the DST Hot Topics and Latest News page, namely updates on the countries noted below; as noted, we’re still waiting for a confirmation on changes proposed for Iran and Argentina.  In some cases, Windows will release hotfixes for specific regions (including Brazil, Egypt) prior to the changes in those countries: watch the DST Hot Topics page and our blogs for more information.

Here’s a list of the DST and TZ updates planned for the December release: thanks to Joel, Steve, Jennifer, Shay and Sophia for helping collect and review the information (and to Clarence for reminding me today that countries really should implement time changes at 2:00AM rather than midnight):

Please note that where we have heard that changes may be coming to a territory but have yet to receive an official confirmation from a government, we indicate that the changes are "not yet confirmed."

As a reminder on our annual cadence (outlined here) and in a prior post, our product teams are moving to an annual product update cadence (with provisions for semi-annual as needed).  Following the Windows regular cadence for publishing newly legislated DST rules and time zone updates, our "Cumulative DST and Time Zone Updates" will be released in November/ December (to the Download Centre and via Windows Update respectively) for the coming calendar year; we’ll also provide for a semi-annual update in the July/August timeframe when needed. 

For each, the window closes for additional updates a few months (generally four to six) prior to the release date. 

As I originally posted here, most Windows applications (and some services) reference the underlying OS for DST and time zone information, but some do not. The product and service groups with offerings that have internal DST or TZ references have agreed to follow the regular schedule for cumulative Windows OS DST & TZ updates. The regular Windows release provide a regular schedule for other product groups to follow, as noted in the DST & TZ Product Update Cadence policy. We hope that this will provide a more predictable way for our customers to anticipate and plan for our cumulative updates

This year (as in 2006 and 2007) the Windows team plans to release the packages to the Microsoft Download Center in November and then to Windows Update in early December.  They will also publish the new or modified TZI keys in an update to Microsoft KB article 914387 for IT professionals and sysadmins who may need that information.  Our goal is that our customers and partners can plan on rolling out and installing/ deploying these regular, scheduled cumulative update roll-ups as they are published.

Let us know if you have questions.
