I bet IT people serving Western Australia are groaning… they’ll be trialling summer time in that state from December 3rd until March, and for the next three years. Way to go to give people plenty of notice, fellas!
The next question is, will the vendors get patches out pronto, or just leave users/support people to figure out a solution for themselves?
Microsoft are on the verge of releasing a patch. When ready it will be found at http://www.microsoft.com.au/timezone. At this stage I don’t know whether it will be released as part of Automatic Updates.
And it is available now at that URL.
