The change to the daylight saving schedule seems to have caused some confusion and a few technological hitches.
The ABC has received scores of calls from people who say their mobile phones and computers have switched back a week early from daylight savings time.
Daylight savings normally ends in New South Wales today, but has been delayed by one week in south-east states in an attempt to harmonise dates across the country.
Problems have been reported with broadcasting, with computer-operated systems failing to operate to the correct time.
It is believed the speaking clock service was also caught out this morning, telling the incorrect time and Telstra says it is investigating the problem.
