After completing testing with Microsoft we can now confirm that there is a need to apply a final update to all Windows operating systems to address deficiencies in the daylight savings patch that was applied at the end of October.Testing has confirmed that the October patches that were applied did not cancel daylight savings calculations after 6th January 2010. The latest Microsoft patch (KB976098) is required to remove daylights savings calculations after January 6th. As per the patch that was applied in October, application of this patch will change your appointments to be one hour earlier after January 6th and until the 28th March 2010.
Unlike the previous daylight savings patches, the current patch may have been applied automatically to your server and workstations (note that this patch IS applied as part of your monthly health checks and updates).
In order to apply this patch, Blue Networks and Technology is recommending the following options:
- For clients who opted to install WSUS, this patch will be applied automatically during your next cycle of workstation updates. Once the patch is applied, your appointments will shift to be one hour earlier. You will need to manually move your appointments back one hour.
- Blue Networks and Technology can configure your server to automatically deploy this patch the next time your workstation is restarted. This will take approximately one hour to configure. Once your workstations are restarted you will then need to manually shift your appointments back on hour.
- Blue Networks and Technology can manually apply the patch to your server (15 minutes) and you can manually apply the patch to all workstations yourselves. The patch is easily applied and does not require a reboot of the workstation. The patch can be accessed by the URL http://support.microsoft.com/kb/976098
In all cases it is strongly recommended that clients update all appointments to include their start time in the subject of the appointment asap.
- Microsoft has reported that the latest daylight savings patch for Windows Mobile will address the issue (kb975353).
- It is not expected that Blackberry devices will be affected by this issue if your gateway server was previously patched in October by Blue Networks and Technology.
- Apple iPhones running the latest firmware are not affected by this issue.
Outlook via Web Access:
Testing has shown that in some cases a restart of the web server is required to resolve inconsistencies with Outlook Web Access.
Internal testing has identified that recurring appointments must be deleted and manually recreated once the kb976098 patch has been installed. These appointments show themselves as being one hour earlier than scheduled once the patch has been applied. An alternative to this is to use the calendar rebasing tool located at URL http://support.microsoft.com/kb/931667 however testing of this tool has shown that appointments generated from public folders are not corrected.
