Clock time?

The first time clock was invented in November 20, 1888, by Willard Bundy, a jeweler in Auburn, New York. A year later his brother, Harlow Bundy, organized the Bundy Manufacturing Company, and began mass producing time clocks. Bundy Manufacturing, along with two other time equipment businesses, was consolidated into the International Time Recording Company (ITR). In 1911 ITR and two other companies were merged, forming Computing Tabulating Recording Corporation (CTR), which would later change its name to IBM. In 1958 IBM's Time Equipment Division was sold to the Simplex Time Recorder Company.
