Australian Time Zones


Riekie

Recommended Posts

Mainland Australia has three time zones, on account of its large geographical range:

  • Eastern Standard Time (EST) - operates in New South Wales, the Australian Capital Territory, Victoria, Tasmania and Queensland, 10 hours ahead of Greenwich Mean Time (GMT)
  • Central Standard Time (CST) - operates in South Australia and the Northern Territory (half an hour behind EST, 9.5 hours ahead of GMT)
  • Western Standard Time (WST) - operates in Western Australia (two hours behind EST, 8 hours ahead of GMT).

Several Australian states observe daylight saving time during the summer season. In NSW, ACT, VIC and SA, daylight savings time applies from the end of October to the end of March and in Tasmania from the beginning of October to the end of March. Queensland, the Northern Territory and Western Australia do not use daylight savings time. Due to the half hour difference between CST and EST, this means that during summer there are five different time zones operating in Australia: GMT+8 (WA), GMT+9.5 (NT), GMT+10 (Qld), GMT+10.5 (SA) and GMT+11 (NSW, ACT, Vic, Tas).

  • Note 2 - The city of Broken Hill (NSW) operates on CST and the few roadhouses along the Eyre Highway in southeastern WA operate on an unofficial intermediate timezone between CST and WST (three quarters of an hour behind CST and three quarters of an hour ahead of WST).

(I'm STILL confused....!)

Wat ek nog steeds nie verstaan nie is by wat jy die +9 ens. moet tel? Wat is Standard time? (Sorrie, het nie aardykskunde gehad op skool nie - net tot Std 7, maar nie in die klas opgelet nie!)

Ooooo. Wat jy by die +9 of wat ook al moet tel is GMT, die tyd in Engeland. So as dit 2nm in London is, dan is dit 11nm in die +9 tydzone. Standard Time en Daylight Savings Time is 'n konsep wat ons nooit in Suid-Afrika oor hoef te geworrie het nie. Dit laat toe vir die langer dae in die somer en korter dae in die winter in die verre noordelike- of suidelike halfrond. Lande naby die ewenaar gebruik gewoonlik nie dié skema nie. Ek was nogal verbaas om te sien Australie het ook daylight savings. Die rympie in Engels se "Spring forward, Fall back" wat 'n aanduiding is wat jy met jou horlosie doen in daardie twee seisoene. In die lente (einde Oktober vir julle) stel jy jou horlosie een uur vorentoe (later in die dag), so 5vm word 6vm. In die herfs stel jy jou horlosie een uur terug (vroeër in die dag), so 6nm word 5nm, bv.

Vat maar 'n tydjie om aan gewoond te raak!

Aaaah - NOU het ek dit! Thanks! Dit is "weird" dat Australië soveel tydzones het - mens sukkel om by te hou! My seun is in Perth - 3 ure agter Sydney - en ek vergeet dit altyd (het hom al 'n paar keer wakker gebel!) Dan is daar my broer in Adelaide (30 minute agter), ons familie in RSA, in Kanada en vriende in London......

Die rympie in Engels se "Spring forward, Fall back" wat 'n aanduiding is wat jy met jou horlosie doen in daardie twee seisoene. In die lente (einde Oktober vir julle) stel jy jou horlosie een uur vorentoe (vroeer in die dag), so 6vm word 5vm. In die herfs stel jy jou horlosie een uur terug (later in die dag), so 5nm word 6nm, bv.

Hendie, oulike rympie om te onthou "Spring forward, fall back" - maar as ek mag korrigeer - alles wat jy sê is reg, behalwe die voorbeeld. m.a.w. einde Oktober (in die Suidelike halfrond) stel mens die horlosie vorentoe, inderdaad, maar dan word 5vm aangestel tot 6vm (nie anders om nie). (bv. op 28 Oktober kom die son op om 5vm. en op 29 Oktober kom die son op om 6vm.) En in herfs word 6nm dan 5nm. (m.a.w. die son gaan skielik nou 'n uur vroeër sak).

Eintlik is dit nie so 'n big deal nie - want mens kry dit eintlik instiktief reg.

Die enigste ding is eintlik net om tred te hou met tydverskille met ander lande en wêrelddele.

Net om 'n kompleksiteit by te sit, net vir die snaaksigheid (so, as iemand my verloor, moenie worry nie): :D

Dan om tred te hou met tyd verskille, veral met noordelike halfrond lande wat ook DST observe

Die tydverskil nou tussen die ooskus van Australië en die ooskus van Noord-Amerika is 16 uur.

Tot 26 Maart (die laaste Sondag van Maart) Sydney het nie meer DST nie - maar Noord-Amerika het nog.

- Dan is die tydsverskil 15 uur.

Vir 'n week - tot 2 April (die eerste Sondag van April) Noord-Amerika het nie meer DST nie. - Dan is die tydverskil 14 uur.

Al twee (Noord-Amerika en Australië) skakel weer oor op 29 Oktober (die laaste Sondag van Oktober). - Dan is die tydverskil weer 16 uur.

(wat wel belangrik is die tydverskil skielik met 2 ure toeneem - en nie net met een, soos met Suid-Afrika waar DST nie geobserveer word nie).

Die maklikste vir my is dat ons so ongeveer 8 ure voor die familie in RSA is. Ons het nie daylight savings hier by ons op die Sunshine Coast nie, so ek kan altyd uitwerk hoe laat dit ongeveer is as ek die familie bel. Hulle weet nie so baie van die tyd nie en ons kry soms sms boodskappe in die middel van die dag. Ek het al heelwat verduidelik dat ek klaar gewerk het vir die dag as hulle eers begin werk, maar hulle vergeet soms.

A lot of Aussies only have two time zones to think about:

Opening Time . . . . and . . . . Closing Time

The last post is more than a month old but I just read it. Great stuff! :)

Well I can add that New Zealand has slipped out of Daylight savings mode last Sunday morning (19/3) so if any of you email me now we are only one hour 'ahead' of Sydney (for a few weeks). That means flying time is a bit shorter now and emails travel faster. :(

NZ High!

yeah, I know what you mean.

Have you noticed that the curtains fade more in summertime with the extra hour of sunlight on them with the clocks forward that extra hour??? :(

When does daylight savings end for Sydney/NSW? Do we then turn 1 hour back or go 1 hour forward? Been there....done that.... still can't get it right! ;)

Hi Riekie,

Next weekend will be the end of daylight saving. When you go to bed on Saturday evening, set all your clocks an hour back.

A good way to remember which way to set the clock is "spring forward and fall back'. In spring time, set your clock one hour forward (for Sydney) and in the fall (autum), set your clock one hour back.

I still get confused myself when I try to work it all out. It doesn't always sound logical.

Thanks for that! You'd make an excellent teacher for Year 1 kids - at last I grasped the concept and there is no way I will now ever forget how it works! Thanks! ;):ilikeit:

Spare some pity for me here - I have clients in every time zone in Australia :ilikeit: I not only have to try and remember what time it normally is in each state compared to Vic, but when daylight savings comes I have to remember which states don't have it and which do too. Many is the day I call a WA client at 7:30am Vic time only to find a very irate client in his PJ's at the other end of the line asking me in tones that promise a painful death........"Do you know what time it is!!" :)

Most of the Aussies I speak to don't really understand it either except that it gives more sunlight hours to play in after work during summer and an "extra" hours' sleep in during the winter. I have one guy who works with me who swears he's tired all summer because of the loss of that prescious one hours' sleep when daylight savings starts. He's counting the minutes until he "regains" his lost hour. :D

Me? I just adjust my clock, change my smoke alarm batteries and get on with it. For me and many others like me it's whatever time of the day my client says it is in his neck of the woods - no matter what my clock says.

Enjoy the lie-in on Sunday. You'll be getting an "extra" hours' shut-eye.

Hi Everyone,

As you know, my husband is busy with his conversion exams to be admitted as a Solicitor in New South Wales.

One of the requirements is a Viva (face to face) Assessment that must be done through Video Conferencing and we have been asked to provide the University with a time in Eastern Australian daylight savings time so that they can book a video conference room on their side.

My question to you… What is Eastern Australian daylight savings time? I went onto Australian’s Time Zone Information Website and it mentions that Daylight Savings time will start on 29 October 2006 and that the time difference is GMT+11. In other words, the time difference gets bigger… (?)

The assessment will be conducted in December 2006. If we say 16:30 Australian Eastern Time, it would be 07:30 in Pretoria, South Africa. Is this correct?

I will appreciate it if you can confirm / clarify this for me.

Have a great day!

Pippa

Hi Pippa

April - October: SA = GMT+2; AES(tandard)T = GMT+10 (8 hours difference)

November - March: SA = GMT+2; AED(aylight)T = GMT+11 (9 hours difference)

Therefore in December, 16:30 AEDT will be 07:30 in S.A., so you are correct! :)

Daylight Saving Time, or "Summer Time" as it's sometimes called, was introduced in the early 1970s by a few States in Australia and New Zealand.

Western Australia adopted it for a year but dropped it.

Basically, from the last Sunday in October, you put the clock FORWARD One hour, making 2am Sunday morning become 3am Sunday.

This applies to New South Wales, Victoria, South Australia and Tasmania (Tas puts its clocks forward on the first Sunday in Oct.)

All through summer, these four States and New Zealand have an hour longer into the summer evening in essence.

We can sit outside and enjoy a barbie until dark at 8:30 instead of 7:30 if we were just on "Standard Time".

Clocks go back in all States that adopted Daylight Saving, and in New Zealand, on the last Sunday in March, making 3am Sunday become 2am Sunday.

Clocks then are back to "Standard Time".

Western Australia, the Northern Territory and Queensland do not put their clock forward at any time of the year and are always on "Standard Time" locally.

The eastern States of Australia are 10 hours ahead of GMT when on "Standard Time" and 11 hours ahead of GMT when on "Daylight Saving Time" in summer-time, after the last Sunday in October.

Pippa, ek het jou vraag hier by Riekie se oorspronklike artikel ingesit. Daar is 'n bietjie meer inligting oor dagligbesparing hier ook. :D

Hi Everyone,

It's me and the time zones again :D .

I see that the Daylight Savings time ended on Sunday, 25 March 2007. Now does this mean that New South Wales, Victoria, South Australia is 8 hours before South Africa :D ?

I received and interview request electronically about a month ago for April 2007 and the interview will be conducted in Melbourne. The electronic invitation indicated that the meeting (interview) was in a different time zone, and when I chose my current time zone it showed 07:00 am (South African time) in the morning. Do you think I should add 8 hours to the 07:00 am South African time to get to the Melbourne time or should I add 9 hours :blink: ?

Please accpet my apologies for asking this, but I am really clueless when it comes to these things :blush: .

Please help!

Lovies, Pippa! X

dont worry. you are right in did change last Sunday.

Not all states do daylight saving. Austalia is ahead of SA time wise.

New times are:

At 00h00 (midnight) in South Africa:

Sydney = 08h00

Melbourne = 07h30

Perth = 06h00

Be careful using your computer becasue if you do not select daylight saving nothing will change.

I hope this helps.

Reid.
