On June 30 2015 at 23:59:59 UTC (19:59:59 EDT), artist Sara Morawetz was standing in the middle of New York’s Times Square with a pair of cymbals. As the clock ticked to the next second, she struck the cymbals together.
This simple performance, titled 61/60, sought to highlight the strange blip of time where the clock read 23:59:60 UTC (Coordinated Universal Time), instead of 00:00:00 UTC.
