The first clocks (sundials) were invented a long time ago, and many historians can't place an exact date on their actual invention. Some believe that they first appeared in 3500 BC. Digital clocks and watches are newer inventions that were created in the modern era.
Punch cards are used with electro-mechanical timeclocks to record and create a paper trail of employee attendance.
