For most GMM for Exchange customers, no updating of either Good or Microsoft software will be needed for GMM calendar events and notifications to display correctly during the one week between the old and new end dates for Daylight Saving time. If the following two items are true, then your environment is prepared for the DST change in November and no additional software updates are required:
· The appropriate Microsoft Operating System DST patch announced January 2007 has already been applied within your environment
· The appropriate Microsoft Exchange 2003 or 2007 patch has been applied within your environment
· You are running Good Mobile Messaging Server and Client version 4.9.3 or later
If you have not applied the Microsoft Operating patch or are not running GMM 4.9.3 or later, then GMM calendar events and notifications between October 28th and November 4th will display one hour early. After November 4th, GMM calendar events and notifications will display accurately.
For
For most GMM for Domino customers, no updating of either Good, Microsoft, or Domino software will be needed for GMM calendar events and notifications to display correctly during the new Daylight Saving Time (If the following two items are true, then your environment is prepared for the DST change in November and no additional software updates are required:
· The appropriate Microsoft Operating System DST patch announced January 2007 and IBM Lotus Domino DST patches has already been applied within your environment, and
· You are running Good Mobile Messaging Server 4.5.6.23 and Client 4.9.3.x
If you are running Good Mobile Messaging Server 4.5.6.24, or upgraded to 4.5.6.24 from 4.5.6.23, and provisioned new users (users who were never enabled on GMM 4.5.6.23) on 4.5.6.24 or later, any recurring appointments that were created before March of 2007 spanning after the new DST times will be off by one hour. To address this problem you have to install a GMM fix-up task that runs periodically and fixes newly added user’s calendars to display correct times on the devices.
If you have not applied the Microsoft Operating System patch and IBM Lotus Domino patch or are not running GMM 4.5.6.23, or 4.5.6.24 with GMM fix-up task, then GMM recurring appointments and notifications in the new DST times will display by one hour off.
GMM for Domino fix-up task information: GMM 5.0.2.49 and later includes a DSTFIXUP add-in task (nGMMDSTFIXUP.exe). This task is scheduled to be run every night at 3 AM (via ServerTasksAt3 variable in the notes.ini of the Domino server on which GMM runs). The purpose of this task is to fix some of the calendar documents that the DST Agent (provided by IBM) acted upon. This task is scheduled to run once per day and it checks for any new GMM users added since the last run.
This task can be scheduled to run more frequently by creating a Program document for the GMM Domino server. To create a program document on the GMM Domino server, open the NAB on the GMM Domino server using the Notes Administrator. Navigate to "Configuration\Servers\Programs" and click on the "Add Program" action button. Enter the 'Program name' as "GMMDOMINOFIXUP", the 'Command line' should be left empty, 'Run At Times' can be left empty if you wish to run the task every hour (for example) and set the 'Repeat interval' to "60" minutes (to run the task every hour), and save the Program document. Note that this task can be run manually by issuing "load gmmdstfixup" on the GMM Domino server console at anytime.

What time zones are impacted?
How does this change impact Good
Appointments created from the handheld or created from the
desktop and synchronized with the handheld will appear one hour off. For recurring appointments created from the
handheld, appointments might appear one hour off or not synchronize at all.
We recommend that users in the affected time zones not schedule
recurring appointments from their handhelds until after any previous years’ DST
changes are in place, or when a software patch is made available by Motorola Good
Technology Group.
Note: Please note that these issues will occur even if users
apply the Windows Mobile or Palm OS DST patches to their handhelds.
MS Exchange Specific: Should the latest MS patches be applied?
Yes, the latest MS patches for Exchange and Windows OS will
fix appointments in Outlook except as specified above.
Lotus Domino-specific: Should the latest IBM patches be applied?
Yes, the latest IBM Agents for Domino should be applied, as
well as the MS Windows OS patches. This will fix appointments in the Lotus Notes
clients except as specified above.
When will this issue be resolved?
We are investigating a server and client patch for the Good
Mobile Messaging 5.0 Service Release 1, which is currently targeted for late Q4
2007*. We will inform affected customers
as soon as the software patch is available for distribution.
*Note: Please note that this date is subject to change.
