Problem Description

New New Zealand Daylight Saving Time rules go into effect in September 2007. Consequently, Cisco Unified Video Conferencing Manager meetings may occur and appear one hour off of their intended scheduled time. Timestamps for Cisco Unified Video Conferencing Manager system logs may also be off by an hour.

Background

On April 30, 2007, the Minister of Internal Affairs issued a statement regarding a change in Daylight Saving Time policy for New Zealand. The change in policy has modified the start and end dates for Daylight Saving Time (DST). Beginning in 2007 and beyond, Daylight Saving Time in New Zealand will start on the last Sunday of September at 2:00 A.M. local time and end on the first Sunday of April at 3:00 A.M. local time.

Specifically for 2007-2008, Daylight Saving Time will begin at 2:00 A.M. local time on September 30, 2007, and end at 3:00 A.M. local time on April 6, 2008.

For more information, see the statement issued by the Minister of Internal Affairs: Daylight saving to be extended.

The old Daylight Saving Time policy dictated that DST started on the first Sunday in October and ended on the third Sunday in March.

Problem Symptoms

Cisco Unified Video Conferencing Manager meetings may appear one hour off from their original time on Cisco Unified Video Conferencing Manager between the old DST dates and new Daylight Saving Time dates during the below time frames in 2007 and 2008:

-September 30, 2007, to October 6, 2007

-March 15, 2008, to April 6, 2008

The Outlook calendar invitation received for a meeting scheduled in the Cisco Unified Video Conferencing Manager web interface and to occur during the above transition periods will not contain the proper New Zealand Daylight Saving Time offset.

Meetings scheduled by users who have the Cisco Unified Video Conferencing Manager Outlook plug-in installed will be an hour off and will not have the proper New Zealand Daylight Saving Time offset.

System logs on the Cisco Unified Video Conferencing Manager server may also show up as one hour off during the above time frames.

Workaround/Solution

To prevent the possibility of future meetings from being scheduled one hour off due to the change in New Zealand Daylight Saving Time policy, the affected Cisco Unified Video Conferencing Manager software must be upgraded.

Meetings that were scheduled prior to the software upgrade and are to occur during the transition period between the old and new DST start and end dates will need to be manually re-scheduled. The transition period between the old and new DST start and end dates are outlined in the Problem Symptom section above.

The following three actions below must be followed to upgrade the Cisco Unified Video Conferencing Manager for the new Daylight Saving Time policy:

  1. Update the MCS server's Microsoft Operating System with a patch for the new DST policy. To find out which MCS OS version is in use, please do the following on the MCS server:

    Start Menu -> Cisco OS Version. To find out which MCS OS version to upgrade to, please refer to the MCS Server Operating System Field Notice for New Zealand Daylight Saving Time.

  2. Every Cisco Unified Video Conferencing Manager end user's PC must upgrade to the appropriate Windows OS and Outlook patch. For more information on updating Windows OS and Outlook for the New Zealand Daylight Saving Time policy change, see New Zealand 2007 Daylight Saving Changes on Microsoft.com.

  3. The affected Cisco Unified Video Conferencing Manager software must be updated with the tzupdater.jar patch and can be obtained from the Cisco IPVC Software Download (registered customers only) page. This patch is only valid for Cisco Unified Video Conferencing Manager version 5.1. For Cisco Unified Video Conferencing Manager versions earlier than 5.1, please upgrade to version 5.1 first before applying the tzupdater.jar patch.

    Installation instructions for the patch can be found below. Please assume %CUVCM% is the directory where CUVCM is installed (the default value is: C:\Program Files\Cisco\Unified Videoconferencing Manager\CUVCMRM).

    1. Copy attached tzupdater.jar to % CUVCM %\jre1.5.0\bin.

    2. Open a CMD window.

    3. In CMD window, set current directory to % CUVCM %\jre1.5.0\bin

    4. In CMD window, run this command line: java -jar tzupdater.jar -u

    5. Restart Cisco Unified Video Conferencing Manager MCS server.

If a problem occurs with the updater, please contact your local TAC representative.

No time change is required on other Cisco Unified Video Conferencing products (MCUs and GWs). Customers who require accurate time on other Cisco Unified Video Conferencing MCUs and GWs should synchronize system clocks to an NTP server. Official NTP servers will automatically adjust to the new DST policy.

Frequently Asked Questions

How to check if the update is successful?

  1. Schedule a recurrence (over one year) with time zone (GMT+12:00 New Zealand Standard Time (Pacific/Auckland)) and invite another user in time zone without DST. For example, GMT+08:00 China Standard Time (Asia/Chongqing).

  2. Log into Cisco Unified Video Conferencing Manager as another user (time zone without DST) in the recurrence, and open the recurrence list, check Meeting Start Time list. Make sure the start time goes forward an hour than usual on the last Sunday in September and back an hour on the first Sunday in April, if so, the new time zone takes effect. Otherwise, there may be a problem with the time zone updater.
