Where does on the clock come from?

on the clock

On the clock means many, many things. The first relates to taxicabs. The taximeter was invented in 1891 by the Germans and put into English motorized hackney cabs in the early 1900s who called them clocks in the UK (usually meters in the US). If a cab is running, the mileage is on the clock—and you’re paying for it.

Around the same time, clocks became commonplace in workplaces, especially factories, where workers would record, for the purposes of pay, when they arrive and leave work using a clock system (clocking in, clocking out). On the clock emerged as an expression meaning “working” and by extension, “getting paid,” even when people aren’t literally clocking in and out.

A third on the clock appears in sports, referring to the amount of time left in a part of the game (think shot clock). This sense surfaces in the mid-20th century. In the sport of golf, a player is put on the clock if they are taking too long to play, meaning the amount of time they get to make a shot gets restricted to keep up a reasonable game pace in that super exciting, fast-moving game of golf.
