Daylight saving time is returning across much of Australia this weekend, with clocks springing forward in NSW, Victoria, South Australia, Tasmania, the ACT and the NT's neighbours. Coverage notes Australians will lose an hour of sleep as the country temporarily splits into five time zones. Attention spans practical advice, including a 15-minute trick to ease sleep disruption, while a Gold Coast mayor is again pushing for Queensland to adopt daylight saving.
- 2University of Toronto sundial surprisingly accurate at reading time●magnificent sundial at University of Toronto taking the midpoint of the 5-minute-wide shadow of the gnomon, the sundial
A sundial at the University of Toronto is drawing attention for its accuracy. A photographer tested it by taking the midpoint of the gnomon's five-minute-wide shadow, which read 3:22; adding the roughly seven-minute correction for October 2 gave 3:29 EST, closely matching the camera timestamp of 4:33 EDT. Observers are calling the instrument magnificent and enjoying the demonstration of how sundial corrections work.
