The default configuration for the time zone “(GMT-04:00) Santiago” in Windows Operating Systems does not reflect the new final date for the daylight saving time defined by the government. This bulletin summarizes the actions recommended for customers in Chile to address the extension of daylight saving time and mitigate its impacts.

Windows Mobile: Preventing Devices from "Falling Back" Early

atsim — Tue, 30 Oct 2007 01:32:50 GMT

A recent update was posted to the Microsoft Daylight Saving Time & Time Zone hot topics page which details impacts to some users of certain Windows Mobile devices, who may have 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.
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. The correct end to DST for 2007 in North America is November 4, 2007. 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.

Calendar appointments showing 1 hour later on recipients' calendar appointments

atsim — Mon, 12 Mar 2007 22:06:00 GMT

Symptom: Any calendaring client may show 1 hour later on a recipients' calendar appointment (Outlook, OWA, Blackberry or Goode devices etc.). The recipient will appear to not follow DST2007 rules. This is true even with OS patches are successfully applied even with rebasing successfully executed. Warning: If the system is not OS-patched or rebased successfully, the symptoms will appear similar to this issue (and the unpatched OS is much more common).

· Explanation: This is caused due to multiple copies of CDO.dll or CDOEX.dll existing on the Exchange and/or BES/Goode servers , and the copy of CDO.dll or CDOEX.dll is not being updated, but the applications (Outlook, OWA, Blackberry, Goode, etc) are using the older version of the dll. This can be created by several applications (unrelated to messaging potentially) which install or copy CDO.dll or CDOEX.dll to a separate directory, then register that rough dll.

· Solution:

o Determine if you have this specific issue,

§ please verify all patches and rebasing issues are successfully applied (for example is the OS clock correct, are meetings the user organized being rebased successfully). If the systems are not properly patched or rebased, the symptoms may appear similar.

§ Verify that if a user who is patched sends an appointment to another user who is patched, that the recipient user is showing that appointment one hour later than originator’s.

§ Search the Exchange server (and BES server etc) for multiple copies of CDO.dll or CDOEX.dll.

1 - Run this: C:\>dir /s cdo.dll

2 - Repeat for all drives.

3 - If there's more than one cdo.dll, you have a problem

Same for cdoex.dll

o Fix:

Exchange 5.5 (CDO.dll only - 5.5 does not use/ship CDOEX.dll)

(note - path to system32 may vary)

1 - c:\winnt\system32\cdo.dll is the correct CDO.dll. Delete all other copies of CDO.dll.

2 - regsvr32 "c:\winnt\system32\cdo.dll"

Exchange 2000/2003 CDO.dll

(again - paths may vary slightly depending on installation)

1 - c:\program files\exchsrvr\bin\cdo.dll is the correct CDO.dll. Delete all other copies of CDO.dll.

2 - regsvr32 "c:\program files\exchsrvr\bin\cdo.dll"

Exchange 2000/2003 CDOEX.dll

1 - c:\Program Files\Common Files\Microsoft Shared\CDO\CDOEX.dll is the correct CDOEX.dll. Delete all other copies of CDOEX.dll.

2 - regsvr32 "c:\Program Files\Common Files\Microsoft Shared\CDO\CDOEX.dll"

How can I tell if the Windows Mobile MSI has been installed and applied correctly?

atsim — Thu, 08 Mar 2007 07:01:00 GMT

Q: What is the best way to determine if the MSI installation of the Windows Mobile patch for DST 07 has been applied? When using a cab file the patch shows up under Remove Programs, however with the MSI it does not.

A: Quick and dirty, do Start, Settings, Clock and Alarms, check to see if you have a GMT-8 Tijuana, Baja California timezone. Make sure that you change the timezone to some other time zone, close the applet, open it again and change it back to make sure the device is actually using the DST2007 rules.

That's new with the update available at http://www.microsoft.com/windowsmobile/daylightsaving.
