Standard Time: New South Wales Time = GMT+10
Daylight Saving: New South Wales Time = GMT+11
Standard Time is 10 hours ahead of Greenwich Mean Time (GMT+10).
Daylight Saving Time is observed in New South Wales, where the time is shifted forward by 1 hour, resulting in a 11 hour difference ahead of Greenwich Mean Time (GMT+11).
After the Summer months the time is shifted back by 1 hour resulting in the normal Standard Time.
On 27 June 2007 the Premier of New South Wales announced that legislation would be introduced to provide New South Wales residents with extra daylight saving.
The legislation was passed by Parliament on 23 October 2007.
Daylight saving for future summers begins at 2 am, Eastern Standard Time, on the first Sunday in October and ends at 3 am summer time on the first Sunday in April . This means that residents in New South Wales have an additional three weeks of daylight saving at the beginning and one week at the end.
The decision to harmonise daylight saving across the south-eastern states and the ACT was made after careful consideration of the impact on both rural and urban communities.
The extended period will provide uniformity for business activities conducted across state lines and is consistent with the Council of Australian Governments' focus on reducing regulatory burdens on business.
Standard time in New South Wales (known as Eastern Standard Time) is the mean time of the meridian of longitude 150 degrees east of Greenwich, England. In other words, New South Wales (except for Broken Hill and Lord Howe Island) is 10 hours ahead of Greenwich.
Standard time in Broken Hill (i.e. the County of Yancowinna) is the mean time of the meridian of longitude 142 degrees 30 minutes east of Greenwich and standard time in Lord Howe Island is the mean time of the meridian of longitude 157 degrees 30 minutes east of Greenwich (9.5 hours and 10.5 hours ahead of Greenwich respectively).
Daylight saving begins at 2 a.m. Eastern Standard Time on the last Sunday in October and ends at 3 a.m. summer time on the last Sunday in March. During daylight saving, summer time in New South Wales is one hour in advance of New South Wales standard time.
Therefore, at 2 a.m. standard time on the last Sunday in October clocks are put forward one hour- the time then becomes 3 a.m. summer time. At 3 a.m. summer time on the last Sunday in March clocks are put back one hour- the time then becomes 2 a.m. standard time.
