This Sunday 7 April the clocks go back one hour to signal the end of Daylight-Saving Time in South Australia.
The official end of Daylight-Saving time is 3am Sunday.
Smartphones should change time if automatic network time and time zone settings are on. You’ll need to change other devices such as microwaves or analogue clocks manually.
