The new daylight savings dates for New Zealand got missed out by Apple in their updates so here’s a link to a page with updates on it for the new DST information. DST starts this weekend in NZ. See New Zealand 2007 daylight savings update for Mac OS X.
BTW – I’ve been reading TidBITS since it was available as Hypercard stacks way, way back in 1990. I admire their longevity and commitment in a field that has seen many come and go in that time.
