Western Australian Daylight Savings Changes for Windows

Western Australia is introducing daylight saving for a trial period commencing December 3, 2006. Several Microsoft® products require updates in order to display the correct time during the daylight saving period.

Western Australia is introducing daylight saving on a trial basis for the next three years.

Microsoft products which are aware of daylight saving time changes need to be updated to include the new Western Australia time zone rules.
The following table shows the start and end dates for the daylight saving period in each year of the trial

Start / End
the hour of 2 a.m. on 03 Dec 2006 / the hour of 2 a.m. on 25 March 2007
the hour of 2 a.m. on 28 Oct 2007 / the hour of 2 a.m. on 30 March 2008
the hour of 2 a.m. on 26 Oct 2008 / the hour of 2 a.m. on 29 March 2009

Note: Both the start and end time are specified in standard time, so the end time is 3 am daylight saving time.

It's not the first time we've had daylight savings, there have been 3 trials of it in the past before a referendum, this is the 4th, each time we vote no and they give us another trial :\

Umm, I don't recall there ever being trials of it before. I could be wrong however, but they just forced us into this one through some sort of loophole.

why doesn't microsoft release this as a critical windows update? can't they release this update as critical for only australian windows xp users? otherwise there is going to be alot of people who don't know about this change. ALso,doesn't windows xp syncronize with the microsoft internet clock? So why would users need this update?

Because 10:30pm in one timezone, is not the same as 10:30pm in another timezone, despite the fact it looks the same from the clock in Windows.

Besides, they can't release the update "as critical for only Australian windows XP", and why should they? How do they know you are from Australia? I know many Australians who have their locales setup as English (United States), so it's best to just apply it to everyone.

How do all the sites that "know" where you're from get that information. Oh, yeah, they look up your IP and compare it to a range from GeoIP (or similar). Is beyond the ability of Microsoft to use something like this?

I remember WU ages ago claiming this was critically required by my UK localised server in the UK on a UK IP. It didn't install (because it wasn't required in any way shape or form, let alone "critically" ) so I had to ignore the thing. Better to NOT make it critical and offer it as a recommended.

According to Wikipedia:

DST was first mentioned in 1784 by Benjamin Franklin in a letter to the editors of the Journal of Paris. However, as the satirical article was humorous, it is extremely clear Franklin did not seriously propose that the French adopt it.

So, what time is it now in Australia (Sydney to be exact)?

I'm curious, because I'm going there in February and I'd like to know what time I'll land (need it for car rental).

So, what time is it now in Australia (Sydney to be exact)?

The same time it always was during Febuary. Sydney is not in Western Australia.

Also, a large portion of Australia uses DLS already. The Problem historically with WA is that it is too geographically large for a normal period of DLS to be used (sept-march). I can't quite remember my high school geography, but it is approximately 3,000km 'wide' and 2000km 'high' at points. This means that natural daylight savings occurs latrally, and that daylight-savings isnt really needed in the northern parts.

And yea... Sydney is the same as always.

Daylight savings time is the most pointless thing we in the U.S. practice. I truly hope Australia discovers through their "trial" that it is completely unnecessary.

Thanks for the completely unqualified and unsubstantiated comment.

People like you make Neowin such a great place to visit.

Did you know that much of the world has some form of "daylight savings?" Did you also know that it saves millions of dollars in electricity costs in the United States? Did you also know it helps prevent millions of pounds of emissions from being needlessly spewed into the atmosphere?


Blue = currently use DST during some part of the calendar year.

millions of dollars of saved energy is PEANUTS and is nowhere near responsible for "millions of pounds of emissions". All of that hype is outdated malarky.

The bottom line is that Daylight Savings Time is a worldwide waste of manpower and resources. All of the people in all of the blue areas have the biological clocks screwed up twice a year because of this foolishness.

Time Zones = good idea
DST = 2x a year mass stupidity

Everything from clocks to cars to microwave ovens etc have to be changed over and over again? Has anyone bothered to calculate how much money is wasted by these actions needed by everyone, or how many accidents occur, flights missed, etc. etc. just because of this lameness?

If you REALLY want to save BILLIONS in emissions, fix our cars and trucks and replace the "always on" transformers on all of our electronics. OR get the streetlamps (the huge nighttime power user) such that they only turn on at night, no matter how long night lasts (you know, simple computers can tell them this daily). Many already do I suspect. :)

DST is a HUGE WASTE in every way and SERVES NO LEGITIMATE PURPOSE.

Oh, and the next time you want to act "superior" over someone else, Raskren, be sure your response isn't simply "hey, look at all the other morons stuck doing this!"
