I looking for a patch to update a Harrier.  I found a patch from MS for 2K3, WM5 and WM6 but that only updates US timezones.  Then I found a MS patch for NZ timezones but that's only for WM5 and WM6!  What gives?

I'm sure this topic has been done to death, I read freitasm's blog posts but couldn't find any resolution?  There's a guy here who made an "unofficial" update for Western Australia that is confirmed as working for WM2K3.  Couldn't something similar be done for NZ DST?  I don't have any experience with Windows Mobile so not sure where one would start.  Does an update already exist?

As a sidenote, according to my tests on a Harrier and what I've read, old DST was second Sunday Oct to third Sunday March (i.e. 07/10/07 to 16/03/08) but the new dates are last Sunday in September to first Sunday in April (30/09/07 to 06/04/08) an increase of 3 weeks from 24 to 27.  The problem I have with that is that this year the third Sunday in March is three weeks before the first Sunday in April meaning a total of 4 weeks difference (turns out 07/10 to 16/03 is only 23 weeks).  I wonder if that is intended or if WM2K3 is way wrong?  If DST hadn't changed would it have ended on 16/03 or 23/03?  Obviously it doesn't really matter, but seems no one really noticed the inconsistent definitions...
