>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):
