In October 2008 we will again be experiencing changes to Daylight Savings in Australia. I wanted to make you aware of these changes so you can plan for them in your environments. The changes to daylight savings can have significant business impact if you don't deal with them in a proactive manner. You could get incorrect times display on computer clocks, calendaring problems and even significant issues with business critical applications. This could cost you and your users a lot of wasted time and money. As you can see from my capture of the date and time on my PC that it's picking up that the time will change to daylight savings on October 5th 2008. So I'm good to go on this machine. Now I just need to go and check all the machines I use to ensure smooth operations during this change.
Daylight savings will now commence on the first Sunday in October (the 5th) and ends the first Sunday in April. This affects Australian Eastern time zones (New South Wales, Victoria, Australian Capital Territory and Tasmania) and Central (South Australia).
So what will be affected?
The bottom line is you need to make sure that systems that could be affected have the correct patches and up to date.
So to help you we have produced some resources that you can use to make sure you have minimal user disruption during this time.

The planning guide is what you really need to make sure everything will keep running smoothly. If you have a strong patch management process then you should see little if any impact at all.

Thanks Jeff, your post helped me by reminding as to when the day light saving is happening.
Busy updating *.* so to speak (Servers, Workstations, Apps etc) and your post pointed one thing out to me Jeff that I hadn't really noticed but checked anyway:-
The checkbox "Remind me one week before this change occurs" is checked on most of my Vista & Server 2008 Machines (Physical & Virtual) yet no reminder has happened which I presume should have happened Sunday 28th September.
Did you get a reminder?
You know I didn't get a reminder either. Maybe it only reminds you if the machine doesn't have the DST patch? Not sure will have to investigate..
Tick Tock Jeff :)
None of the Server 08 GUI/Core or Vista machines gave the notification outlined above.
All Vista/Server08-GUI&Core/Server03/XP rolled over fine and none have popped up a message stating "Your Clock has been adjusted for daylight savings time etc etc..."
Will check server apps later today. :P
Hehe... The comment above shows October 4 12:09PM
Your blog runs at US EST :P

The past hour went 'really' quick. :P
I understand for client operating systems the changing of DST calendar can be a nightmare for tech support.
But for web based application there is no reason why they don't all sync to UTC. There are companies that have IT server systems with local time - THIS IS ASKING FOR TROUBLE.
