Updating Windows Mobile-powered devices for the new Daylight Saving Time
Updated March 5, 2007
Congress has changed the dates for Daylight Saving Time (DST) in the United States starting in 2007. Canada has adopted similar DST dates. These changes could cause clocks and Microsoft Outlook calendar appointments on Windows Mobile-powered devices to display incorrect times for March 11 – April 1, 2007 and October 28 – November 4, 2007 and again in subsequent years. You can find more information about the exact dates and potential impact in the Changes in DST section.
To make sure your appointments on your Windows Mobile devices are accurate, you’ll need to update your device. If you regularly synchronize your device with your PC, you’ll need to update Microsoft Windows and Microsoft Outlook as well.
We have three tools that will help your make these updates:
2007 Time Zone Update for Microsoft Windows Operating Systems
Outlook Time Zone Update Tool
Daylight Saving Time 2007 Update Tool for Windows Mobile
Note: All users in the United States, Canada and Mexico should immediately install these updates. Users in other countries should install these updates if they travel to the United States, Canada and/or Mexico or if they make calendar appointments that include attendees that are based in the United States, Canada and/or Mexico.

IMPORTANT
Please be sure to follow all steps below completely and in order. And be sure to complete ALL steps.
Follow only one set of instructions below, depending on if you synchronize your device to a PC:
If you connect your device directly to a PC with a USB cable or cradle, follow the instructions for Windows Mobile users who connect to a PC to synchronize.
If do not synchronize your device or phone with your PC or you only synchronize your phone or device wirelessly with a Microsoft Exchange Server or, other e-mail and calendar systems, follow the instructions for Windows Mobile users who do not connect to their PC.
For Windows Mobile users who connect to a PC
First make sure your PC is up-to-date.
(see http://www.microsoft.com/dst2007 for more details)
NOTE: Make sure you update all PCs that you may connect to your Windows Mobile device.
For Windows XP SP2 and Windows Server 2003, the update has already been deployed using Automatic Updates and should be installed if you have Automatic Updates enabled. If you want to verify that it is installed, you can visit Windows Update and make sure all High Priority items are installed.
For Windows 2000 or earlier versions of Windows XP, see the 2007 time zone update for Microsoft Windows operating systems to the clock on your PC.
First make sure to update your PC by installing the 2007 time zone update for Microsoft Windows operating systems; which can be found here. This will update the clock on your PC.
If you use Microsoft Outlook to synchronize your calendar, download and run the Outlook Time Zone Update Tool which can be found here. If you do not use Microsoft Outlook, proceed to step 4.
Check to make sure you have the latest version of ActiveSync, which is ActiveSync 4.5.
Next, connect your Windows Mobile device to your PC, then download and run the Daylight Saving Time 2007 Update Tool for Windows Mobile which can be found here.
For Windows Mobile users who do not connect to their PC
For users that do not connect to PCs, there is an update file (CAB) available to make this update. (Note: there are a number of ways to install a CAB file and below outlines a popular method). Also, Microsoft Exchange users should contact your system administrator to make sure your Exchange Server has been updated as well.
Using the Microsoft Internet Explorer Mobile browser on your device, go to http://www.microsoft.com/windowsmobile/ and download the Daylight Saving Time 2007 Update your Windows Mobile device. This file will install the update directly on the device. On your device, navigate to the file you downloaded, and then click on it to install the update. If you are unable to download the link proceed to step 2.
If you are unable to access the link in step 1 on your device, open Windows Internet Explorer on your PC and click here to start the download process. After downloading the file, attach it to an e-mail and send it to an account you can access on your device. On your device, open the e-mail and save the attached file; on some devices, you may need to synchronize your e-mail a second time to download the attached file. Then navigate to the file on your device and click on it to install the update.
NOTE: After you install this update, your device will automatically restart to ensure that the update is complete.
Installation tips
Rapid succession of steps is important
Run the Outlook Time Zone Update Tool on your PC as soon as possible after the DST update is applied to all of your PCs. If meetings between March 11, 2007 and April 1, 2007 are scheduled after the DST files are installed but before the tool is run, meetings will erroneously be moved one hour earlier. To correct such calendar items, organizers should manually update such meetings to ensure they are scheduled accurately for themselves and all invitees.
All connected devices must be updated
Even if you correctly update your PC with the DST 2007 update, when you view your calendar from a non-updated mobile device running Windows Mobile, your meetings during the extended DST period will be shifted by one hour. Meetings created on your non-updated device will need to be updated on your PC by running the Outlook Time Zone Update Tool again.
If some users have not updated their Outlook, it will affect other users
The Outlook Time Zone Update Tool only updates meetings for which the user is the organizer, and then automatically sends updates for those meetings to attendees. Meetings that you are invited to but did not organize will not be updated until the organizer updates the meeting and prompts you to change to the correct time. Additionally, meetings created by a delegate on your behalf from an non-updated PC will need to be updated on your PC by running the Outlook Time Zone Update Tool again.
What you can do to ease the transition
All Windows Mobile powered device users affected by the time change should give extra attention to meetings and appointments scheduled between March 11 and April 1, 2007, and between October 28 and November 4, 2007. View any appointments that fall into these date ranges as suspect until you communicate with all meeting invitees to make sure that the item shows up correctly on everyone’s calendar.
Include the time of the meeting in the e-mail request so that invitees can double check the correct meeting time. Example: “Project brainstorming - 11:00 a.m. Central Time.”
When in doubt, verify the correct time with the organizer.
Prior to applying the DST files, print out your weekly calendars for the affected time periods so that you can keep track of which meetings were scheduled before and after you run the tool.
Changes in Daylight Saving Time
Daylight Saving Time (DST) will now start three weeks earlier (2:00 a.m. on the second Sunday in March) and will end one week later (2:00 a.m. on the first Sunday in November).
Change in Daylight Saving Time:

Updating your device
Your device stores the pre-2007 DST dates in a table in its memory. Installing an update to the stored DST dates will prevent the problems described above.
