Remember all the hassles with Windows a few years ago when both the US and NZ extended their daylight-saving periods?
Not just Windows, but Apple who did not issue an update for Mac OS X until some weeks after the NZ daylight saving change and recommended on their forum that NZers just adjust the system clock by one hour for the week or two that it displayed the wrong times, without warning that certain entries one put into the Calendar program (and elsewhere) would end up in the wrong hour when one corrected the clock back. In contrast Linux distributions had updates for tzdata well in time for the NZ DST change.
Does OS X set the system clock in local time rather than UTC? Because, fiddling UTC time just to compensate for a wrong local-time offset is not a good idea.
