Normally, the computer's clock automatically changes from standard time to daylight-saving time. In 2000, however, several states and territories of Australia changed the start date of daylight-saving time to accommodate the Olympic Games in Sydney. The Mac OS Date & Time control panel was not programmed to change to daylight-saving time for this one-time event. Follow the steps below to manually set up the Date & Time control panel for daylight-saving time.
| State or territory | Change to
daylight-saving time | Change to standard time |
| South Australia | 2000-10-29 | 2001-03-25 |
| Victoria | 2000-08-27 | 2001-03-25 |
| Australian Capital Territory | 2000-08-27 | 2001-03-25 |
| New South Wales | 2000-08-27 | 2001-03-25 |
| Tasmania | 2000-08-27 | 2001-03-25 |
- Clocks are advanced at 02:00 by one hour on start date for daylight-saving (summer) time.
- Clocks are wound back at 03:00 by one hour on end date for standard time.
