A. Server Operating Systems

The following links provide details for updating servers with the New Zealand 2007 DST information:

B. GroupWise Agents



GroupWise 7 has an updated WebAccess and GWIA agent, and GroupWise 6.5 ONLY requires Webaccess to be updated. The other GroupWise agents (POA, MTA) DO NOT need to be updated unless they are on the same server as the updated GWIA and/or Webaccess because they share some of the same files (See the update documentation for more details). The updates are available at the following locations:

GroupWise 7

DST changes are in GW 7.0.1 POA, MTA, GWIA and Webaccess release patch date of 21 December 2006 or newer.

NOTE: A DEFECT WAS RECENTLY DETECTED IN THE WAY GWIA HANDLES ICAL APPOINTMENTS FOR THE NEW ZEALAND TIMEZONE SCHEDULED FOR AFTER THE DST CHANGE DATE. THE GWIA COULD CAUSE APPOINTMENTS SENT TO OTHER MAIL SYSTEMS AND RECEIVED FROM OTHER MAIL SYSTEMS TO APPEAR INCORRECT BY ONE HOUR. AN UPDATE TO THE GWIA THAT SHOULD FIX THE ISSUE ALONG WITH THE LATEST GROUPWISE 7.02 HOT PATCH SOFTWARE CAN BE DOWNLOADED FROM THE ABOVE GroupWise 7 LINK. 
CAUTION: THIS GWIA IS BASED ON GROUPWISE 7.02 HOT PATCH UPDATE. ALL OTHER AGENTS ON THE SAME BOX SHOULD BE RUNNING 7.02 HOT PATCH AGENTS AS WELL. IF GROUPWISE AGENTS ARE ALREADY AT 7.02 HOT PATCH LEVELS, GWIA IS THE ONLY PIECE THAT NEEDS TO BE UPDATED. ADDITIONALLY, IF POA'S ON OTHER SERVERS IN THE SYSTEM ARE NOT UPDATED TO HOT PATCH CODE, THEN POP AND IMAP WILL NOT FUNCTION PROPERLY AFTER GWIA HAS BEEN UPDATED. FINALLY, IF THE WEBACCESS AGENT IS UPDATED TO THE HOT PATCH CODE AND THE POA'S IN THE SYSTEM ARE NOT, THIS WILL BREAK THE ABILITY FOR THE WEBACCESS AGENT TO TALK TO THOSE POST OFFICES.

GroupWise 6.5

DST Changes are in GW 6.5 Post SP6 Webaccess release patch date 3 November 2006 or newer.


GroupWise Messenger does not need to be updated as it relies on the OS time zone definitions. Make sure that these are updated as referenced above.

Users of the Blackberry Enterprise Server (BES) should refer to any RIM advisories for more information on device updates and other information.


NOTE: PLAN CAREFULLY IF UPDATING TO GROUPWISE SECURITY HOT PATCH RELEASES (SP2 HOT PATCH 1). THESE AGENTS ARE INTENDED TO UPDATED AT THE SAME TIME BECAUSE OF THE SECURITY FIXES IMPLEMENTED.



C. GroupWise Time Zone Definitions Maintained by ConsoleOne

The GroupWise time zone definitions need to be modified with the new transition rules. Follow the Steps listed below for making these changes:

1. Launch ConsoleOne

2. Connect to the Primary Domain

3. Click Tools | GroupWise System Operations | Time Zones and modify the following Time Zones


For the Aukland/Wellington timezone, change the definition to the following:

Start Day:Last Sunday of September

Last Day:First Sunday of April


Note:After updating the time zone database, you MUST restart all agents to ensure that updated time zone information takes effect.

D. GroupWise Clients

It is not necessary to update GroupWise clients. GroupWise clients depend on the workstation's operating system for time zone information. Updating the operating system's time zone information helps ensure that GroupWise appointments are scheduled correctly.

End users will need to update previously scheduled events and reset their Work Schedule Start and End times. See section F below for details.



E. Workstation Operating Systems

Windows Workstations:


Make sure that Windows Workstations have been updated as per Microsoft's Advisory.


Linux (SLED) Workstations:


Make sure that SLED Workstations have been updated as per Novell's Advisory.



F. End User Impact Issues

1. Consequences of using old DST information

Before a workstation's time zones are updated, an appointment scheduled for the time periodbetween the old and new DST transition dates could be off by one hour. For example, an appointment scheduled to occur between September 30 and October 6, 2007 (the new and old DST start dates), will be scheduled at the wrong time because wrong DST information will be used. This will only be apparent after updating to the new DST transition rules.

This behavior also applies to appointments scheduled to occur between March 16 and April 6 of 2008 (the old and new DST end dates), or during any similar period in future years. After a workstation's time zone definitions are updated, appointments can be correctly scheduled for these time periods.

2. What is the best way to handle this?

1. Update workstation time zone definitions as soon as possible.

The best course of action is toupdate workstation time zone definitions in a timely manner. This is most effectively completed by applying the appropriate updates provided by the workstation operating system vendors. The sooner this is done, the less likely users will create appointments in the affected time periods that will be incorrect.

2. Advise users to inspect appointments in the affected time periods and, if necessary, adjust them.

Users may have already created appointments in these time periods, or may do so before the workstation's time zones are updated. After a workstation is updated, users should be advised to inspect appointments in those time periods and adjust them if necessary. Section 3 below provides steps to adjust different scheduled events.

3. Advise users to reset their Work Schedule Start and End time .

3. Adjusting scheduled Events

Adjusting Posted Appointments:

  1. Drag and drop the appointment to the new time
    or

  2. Open the appointment, modify the time, then post

Adjusting Sent Appointments:

  1. Drag and drop the appointment to the new time. When prompted to edit, choose no. The old appointment is retracted and the new one sent.
    or

  2. Select the appointment. Choose the Resend menu option. Modify the time (and other changes if desired) then click Send. Choose Yes to retract.

Adjusting Posted All-Day Events:

  1. Drag/Drop the all-day event onto the same day.
    or

  2. Open the item, click the all-day event check box, then click Post

Adjusting Sent All-Day Events:

  1. Select the all-day event. Choose the Resend menu option. Click the all-day event check box, then click Send. Choose Yes to retract.


Adjusting Received Appointments or All-Day Events:

  1. Contact the organizer and ask him or her to adjust and resend the item.



4. Resetting the Work Schedule Start and End times

The current work schedule time Start and End times are displayed next to the "Work Schedule” group box title on the Tools – Options – Date and Time dialog. Even if the Work Schedule Start and End times are displayed correctly, performing the following steps ensures that the correct Start and End times are adjusted for the corrected DST transition rules. These steps should only be applied after the workstation(s) have been updated.

  1. In the GroupWise client Choose Tools | Options | Date and Time...

  2. Change the Work Schedule - Start time and End time values to something different

  3. Click OK

  4. Choose Date and Time... again

  5. Set the Start time and End time values back to the original or desired values

  6. Click OK

  7. Click Close



G. DST Adjustor Tool

The DST Adjuster Tool that was created for North American Customers during their DST time change HAS NOT been modified for use with the New Zealand time shift.

Novell has partnered with Omni to provide the Riva New Zealand DST module. This module is available free of charge to all New Zealand Novell GroupWise customers who need a solution for the recent changes to the start and stop dates for Daylight Savings Time (DST). Running the New Zealand DST module will automatically create a Query Folder in the Root of each mailbox. The Query folder will display all appointments that fall into the configured date range. The user can then confirm the times are correct for appointments that fall in the new DST time range.

NOTE:
The administrative workstation that will be used to install, configure and execute Riva must have its Regional and Language Options set to (English) New Zealand (Control Panel - Regional and Language Options). The Riva New Zealand DST module will ONLY appear and be available to be configured if the workstation's Regional and Language Options setting is correctly configured to (English) New Zealand.
