Problem Description

The operating systems of most Cisco products that support Daylight Saving Time (DST) have built in mechanisms to automatically change the times, based on current user-selected rules. Once the new DST is implemented, the time on devices that maintain time zone information will continue to change according to the old method, unless changes are made. Further, as the JDK/JRE (Java) runtime facilities are themselves subject to the same update requirements, certain components of the product that utilize the JDK/JRE are required to have the Java Platform JDK DST Timezone Updater ("TZupdater") patch tool applied. The tool is available directly from Sun Microsystems' Sun Developer Network.

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 Web Collaboration Option, Cisco Media Blender and Cisco Collaboration Server Dynamic Content Adapter.

Cisco is not aware of any ramifications of date/time presentation errors with these options under normal use, other than logfile timestamps. If running the Cisco Web Collaboration Option Database server under Oracle, however, data event time references may be misconstrued in the absence of the corresponding patch from Oracle.

Cisco E-Mail Manager Option

Failure to accommodate the 2007 New Zealand DST time change can result in date/time anomalies, including timestamp and event logging references.

Implementing the JRE/JDK patches is not an option for Cisco E-Mail Manager Option. Manual workarounds should be implemented. Follow the directions shown for the two dates.

Once the appropriate patches are applied, the workaround must be undone to meet compliance with the new New Zealand DST dates. The manual workaround is also applicable to the Cisco E-Mail Manager Option Database servers.

Workaround/Solution

Microsoft Windows Considerations

Apply the Windows system maintenance (patch or manual process, as appropriate) per the Microsoft guidelines. Questions or special consideration issues should be provided directly to Microsoft; Cisco Enterprise and Hosted Contact Center customers have responsibility for administering their own Windows server operating system.

Cisco Web Collaboration Option

Customers should apply the TZupdater tool -1.2.2 for JDK 1.4.1. As the Collaboration Server is maintained in a private file area, instructions specific to the product file structure are provided herein.

The Collaboration Server running in an Oracle database environment requires Oracle's own DST maintenance patch in order to transition the 2007 New Zealand DST date change without incident. Contact your Oracle technical support representative for further information.

Upgrade JDK DST Timezone Update Tool 1.2.2 for Cisco Collaboration Server:

  1. Stop IIS and World Wide Web Publishing Service on CCS Server.

  2. Visit Java SE Downloads with your browser of choice.

  3. Select the Download button to the right of the choice "JDK DST Timezone Update Tool -1.2.2"

    Note: You will need to log-into a Sun Online Account before downloading the patch. If you do not have a Sun Online Account, you can register for one free-of-charge. A valid email address is required for registration.

  4. Download the patch to a folder of your choice on the Cisco Web Collaboration Option system. The patch comes in the form a zip file.

  5. Unzip the contents of the patch to the same folder. There should now be a file present named "tzupdater.jar".

  6. Open a command-line window and browse to the path where tzupdater.jar is located.

  7. Issue the following from the command-line:

    [CCS Installed Drive]:\Cisco_CS\jdk\bin\java -jar tzupdater.jar -u -v

    where "u" and "v" are both lower-case letters.

    Again, this entire command is issued from a command-line window after browsing to the same folder as where "tzupdater.jar" is located.

  8. The output from the above command should be similar to

     
    java.home: c:\Cisco_CS\jdk\jre 
    java.vendor: Sun Microsystems Inc. 
    java.version: 1.4.1 
    JRE time zone data version: tzdata2002c 
    Embedded time zone data version: tzdata2007f 
    Extracting files... done. 
    Renaming directories... done. 
    Validating the new time zone data... done. 
    Time zone data update is complete. 
    
    
  9. Start IIS and World Wide Web Publishing Service.

Cisco Media Blender Server

Upgrade JDK DST Timezone Update Tool 1.2.2 for Cisco Media Blender Server:

  1. Stop IIS and World Wide Web Publishing Service on the Cisco MB server.

  2. Visit Java SE Downloads with your browser of choice.

  3. Select the Download button to the right of the choice "JDK DST Timezone Update Tool -1.2.2"

    Note: You will need to log-into a Sun Online Account before downloading the patch. If you do not have a Sun Online Account, you can register for one free-of-charge. A valid email address is required for registration.

  4. Download the patch to a folder of your choice on the Cisco MB system. The patch comes in the form a zip file.

  5. Unzip the contents of the patch to the same folder. There should now be a file present named "tzupdater.jar"

  6. Open a command-line window and browse to the path where tzupdater.jar is located.

  7. Issue the following from the command-line:

    [CMB Installed Drive]:\CiscoMB\jdk\bin\java -jar tzupdater.jar -u -v

    where "u" and "v" are both lower-case letters.

    Again, this entire command is issued from a command-line window after browsing to the same folder as where "tzupdater.jar" is located.

  8. The output from the above command should be similar to

     
    java.home: c:\CiscoMB\jdk\jre 
    java.vendor: Sun Microsystems Inc. 
    java.version: 1.4.1 
    JRE time zone data version: tzdata2002c 
    Embedded time zone data version: tzdata2007f 
    Extracting files... done. 
    Renaming directories... done. 
    Validating the new time zone data... done. 
    Time zone data update is complete.
    
  9. Start IIS and World Wide Web Publishing Service.
