Time Clock Piece (One Year Performance 1980–1981) (1981)

For one year, Tehching Hsieh punched a worker’s time clock located in his studio, on the hour, every hour. Marking the occasion by taking a self-portrait on a single frame of 16mm film, the resulting reel documents a year in his life at approximately one second per day – a pace that is polar opposite of the enduring length of the original performance. The punch cards, witnessed by a third party for authenticity, and other ephemera, document Hsieh’s life restructured around this highly repetitive task.
