Paraguay DST 2014 Fallback                                   

The government of Paraguay announced in 2013 that DST period was going to be reduced.  With this, DST would be ending fourth Saturday of March at 23:59:59. In order to address this change, we released a hotfix. You can find more information on this blog https://blogs.technet.com/b/latam/archive/2013/03/21/paraguay-dst-2013-fallback-update.aspx.

 Last year hotfix only was covering previous year change. In order to make this change consistent for the rest of the years, we released hotfix KB 2935092. This hotfix is now available for all supported operating systems: Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, Windows 7, Windows Server 2008 R2, Windows 8, Windows Server 2012, Windows 8.1 and Windows Server 2012 R2.

We want to make you aware that in addition to Microsoft products, other software, OS releases and hardware (phones, routers, switches and managed devices) may require updates and/or changes.

If you installed last year hotfix, it will be necessary to install this new hotfix to be ready for the upcoming DST change.

General recommendations

 

  • Install the hotfix KB 2935092 as soon as possible.
  • Please note that if you adjust the machine’s clock manually, you may have adverse effects on your environment. This procedure is not supported by Microsoft.
  • Contact Microsoft Support prior to any modification if you are unsure about the steps to follow in order to be prepared for the Daylight Saving Time change in Paraguay.

How to correct Outlook calendars          

Customer needs to follow the steps described on KB931667 to update Outlook calendar. Also, you can refer to the following article https://support.microsoft.com/gp/cp_dst “Daylight Saving Time Help and Support Center”.

Recommendations to minimize the impacts on Outlook/Exchange:

 

    • Simulate the changes on a lab environment, so you know what will happen and what to expect.
    • Work in conjunction with the operating system team to update the DST dates as soon as possible to minimize the chance of users creating new appointments during the delta period before the operating system DST dates get updated.
    • Before doing any change on the DST information, request the users to print their schedule so they have a reference to follow in order to manually update the appointments later if needed.
    • Take a full online backup of your Exchange Servers in case you decide to use the Exchange Calendar Update Tool.
    • For the meetings with multiple attendees only the meeting requestor should update the time and send the update to the others.
    • Include the time of the meeting in the e-mail request so that invitees can double check the correct meeting time (such as, "Project brainstorming - 11:00 A.M. Asuncion Time").
    • Exercise caution with the appointments and meetings in the extended DST period. When in doubt, verify the correct time with the organizer.
