Now this a very stealthy *gotcha!*
- The patch requires removal after DST ends
- The patch will need to be re-applied IF the machine is “repaired” or service patched
- Outlook issues caused by the DST changes are *Evil* !
Australian Daylight Savings Changes for Microsoft Products for the Year 2006
[Microsoft]
The Commonwealth Games are scheduled to be held during March 2006 in Melbourne Australia. Several Australian states including New South Wales, Victoria, Australian Capital Territory, South Australia and Tasmania, have changed the Daylight Savings transition end dates to the first Sunday of Apr 2006.
Daylight savings end for 2005/2006
For the Year 2006 only, the published Daylight Savings end transition dates (as at 14th September, 2005) for each of the states of Australia are:
Victoria 27/03/2006 To 2/4/2006
ACT 27/03/2006 To 2/4/2006
NSW 27/03/2006 To 2/4/2006
Tasmania 27/03/2006 To 2/4/2006
South Australia 27/03/2006 To 2/4/2006
Note: Clocks are advanced at 2am by 1 hour on start day to become Summer Time. Clocks are wound back at 3am by 1 hour at end day to become Standard Time.
The change to Daylight Savings will affect the transition settings for the following time zone rules:
(GMT + 10:00) Canberra, Melbourne, Sydney
(GMT + 10:00) Hobart
(GMT+09:30) Adelaide
NOTE 1: on April 2, you have to UN-APPLY the patch!
NOTE 2: there is no patch for WinCE, PocketPC or Windows mobile … obviously PDA users don’t care about timezones (or calendaring?) you have to manually adjust your device to the +11 time zone – on the 2 April you have to remember to change it back +10 time zone again.
1. Aussie Microsoft calendar mess
[WOW - Office Watch]
…
Lots of Aussies read Office Watch and the problem is such a blot on Microsoft’s copybook that we’re devoting most of this issue to explaining this mess.
…
When you store an appointment in Outlook it records the UTC time plus the time zone that applies to the appointment – you don’t see that directly, just the adjusted date and time show in Outlook. That time zone information comes from Windows.
…
Because Windows has not been setup with the adjusted Aussie daylight savings dates already, any appointments you’ve created in the extra summer time week for 2006 will be off by one hour.
…
This means that during the ‘extra’ week you have to ensure that no appointments (one off or recurring) for the same dates in future years are made until after you’ve patched all Windows machines.
…
Hmmm, another good reason to dislike Outlook!

Compare this hodge-podge fix to the elegant solutions available in Linux, Unix and OS X. Groan!
