Products Affected

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.

The time zone update reflects the recent Daylight Savings Time (DST) extensions announced by the New Zealand Department of Internal Affairs (see New Zealand Department of Internal Affairs official DST announcement). In New Zealand beginning September 2007, DST will start one week earlier than usual and end two weeks later. Specifically, New Zealand DST will start at 2:00 A.M. on the last Sunday in September and end the first Sunday in April at 3:00 A.M.

Background

Time zone information is stored in a time zone database (called the tz database or zoneinfo). The tz database is updated periodically to reflect changes made by political bodies to time zone boundaries, UTC offsets, and daylight-savings rules. For more information see the ZoneInfo home page. This notice is intended to both alert you to the specific impact of the Daylight Savings Time change and to detail the necessary steps that should be taken.

Specifically this notice provides information about the time zone update referred to as tz2007f or tzdata2007f.

Microsoft Windows Considerations

In general, many Cisco Contact Center product components rely on the underlying Microsoft Windows operating system to manifest time zone context, including DST start and end event timing. For this reason, all Cisco Contact Center customers must adhere to Microsoft's guidance for Windows system maintenance to ensure their systems are updated for the New Zealand DST change.

Windows Server 2003 and Server 2003 Service Pack 1 customers can obtain a software patch from Microsoft that will apply the necessary update to their servers. Client applications running on Windows XP SP2 can likewise obtain this update. See the Microsoft link following this paragraph. Windows 2000 Server customers should contact Microsoft regarding procedures applicable to their version of the operating system, and to patch availability as it applies to holders of an extended support agreement (if applicable). Windows 2000 Server customers may also use the Microsoft TZEDIT tool to alter DST information.

Products listed above

The Cisco Products above run on Microsoft Windows Server 2003, Microsoft Windows Server 2000, Microsoft Windows Pro 2000 and Microsoft Windows XP. The operating system patch listed above under Microsoft Windows Considerations must be applied to all Windows Server 2003 servers, Microsoft Windows Server 2000, Microsoft Windows XP and Microsoft Windows Pro that run the products listed in this field notice.

The Cisco Products above store the time zone database within its internal tables. Sun Microsystems provides a tool - TZUpdater (version 1.2.2) - to adjust these dates to the new values.

The TZUpdater tool can be found here: Sun's Java Download Page

Problem Symptoms

Failure to update the operating system or Java runtime environment for products listed in this field notice will result in a one hour time discrepancy.
