>Description:

	New Zealand changed the law for daylight savings time.  The
	new law is NZDT begins the last Sun of Sept (starting in
	2007) and NZST resumes the 1st Sunday in April (starting
	in 2008).  Attached is a diff to /usr/src/share/zoneinfo/australasia
	reflecting this change.

>How-To-Repeat:
	nothing to repeat.
>Fix:

	If in New Zealand, patch /usr/src/share/zoneinfo/australasia 
	make clean && make install from /usr/src/share/zoneinfo then rerun
	tzconfig to install a new /etc/localtime file for your system.


	Attached is the diff (version numbers have not been bumped):
