It's that time of year again when the clocks are wound back to mark the end of Daylight Saving in New South Wales. 

Daylight Savings officially finishes at 3am on Sunday 3 April so, before bedtime, it's always a good idea to re-set the clocks. 

The regulation of time is a State Government responsibility and, in New South Wales, the Standard Time Act 1987 governs standard time and daylight saving.  

The clock moves back on the first Sunday in April and forward again in September, although allowances are made for the area in and around Broken Hill and for Lord Howe Island. 

The trick is to know which way to go as daylight saving switches from one to the other. 

The NSW Attorney General Mark Speakman – occasionally known as 'The Minister for Time' - says that, at this time of year, a simple song can help. 

And no, it's not the Time Warp.

"Whether you change your clocks before bed on Saturday night or set the alarm for 3am Sunday, just think of iconic singer Cher and her 1980s anthem If I Could Turn Back Time," Mr Speakman said. 

"This weekend, every NSW resident will turn back time – by one hour. At 3am on Sunday, our clocks will go back one hour to 2am." 

"Most internet connected devices will update automatically, but don't forget to adjust manual clocks – and best of luck to you when it comes to clocks on microwaves, stereo systems and vehicle dashboards," he said. 

Legislation to harmonise daylight saving in NSW with the south-eastern states and the Australian Capital Territory was passed by the NSW Parliament on 23 October 2007, however, Queenslanders voted down Daylight Savings thirty years ago. 

In February 1992 a state referendum narrowly defeated the implementation that would keep Queenslanders in line with their southern neighbours. 

They run with the Northern Territorians and Western Australians where daylight savings is not observed. 

For the New South Welshmen, pull up the doonas and grab yourselves an extra hour of shut-eye on Sunday (tomorrow) morning.
