University of Toronto sundial surprisingly accurate at reading time
Original: 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.
Why now: A simple real-world test showed the historic sundial's accuracy, delighting people interested in astronomy and timekeeping.
