VG248 - 1.3(x)

VG248 versions 1.3(x) and earlier are affected.

Problem Description

New New Zealand Daylight Saving Time rules go into effect in September 2007.

Consequently, the logs and clock on the VG248 may appear one hour off.

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

The time shown in the following locations may be an hour off between the new and old Daylight Saving Time start and end dates during the below timeframes in 2007-2008:

-September 30, 2007, to October 6, 2007

-March 15, 2008, to April 6, 2008

  1. The clock on the VG248 user interface

  2. Timestamps shown in system logs

  3. Caller ID timestamp shown on analog phones connected to a VG248

Workaround/Solution

The VG248 receives its clock from the Cisco Unified Communications Manager (CallManager). Please upgrade the CUCM server to an appropriate software version based off of the Cisco Unified Communications Manager Field Notice for New Zealand Daylight Saving Time.

To ensure the new clock is pulled from the Cisco Unified Communications Manager immediately, please reboot the VG248 after the CUCM server is successfully patched.
