A new Microsoft Knowledge Base article is up – KB 974176 – noting the hotfix now available to update the Daylight Saving Time for the “(GMT+02:00) Cairo” and “(GMT+08:00) Perth” time zones for the year 2009 for Windows Server 2003-based, Windows Vista-based, Windows Server 2008-based, and Windows 7-based computers.

I have to recommend that in order to achieve more seamless transitions to new DST rules and time zones, governments should provide 1) official confirmations of planned changes to DST and time zones, and 2) provide ample advance notice and concentrated efforts on promoting the change to the affected citizens is a requirement. If you look at how Australia approached their upcoming change in in 2008 (more details are available here), the national government allowed eight months or so between the announcement and the actual change.
