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.
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 previous Daylight Saving Time policy dictated that DST started on the first Sunday in October and ended on the third Sunday in March.
On April 30, 2007, Hon Rick Barker, Minister of Internal Affairs, announced a three week extension to the period of daylight saving. Daylight saving now runs from the last Sunday in September until the first Sunday in April.
