What does clocker mean?
A clocker is a person whose job or habit is to measure and record time — whether of workers or, far more commonly, of racehorses. In American horse racing, a clocker is a familiar figure at the track: standing near the rail with a stopwatch or binoculars, he or she times the morning workouts of thoroughbreds and makes those figures available to bettors, trainers, and publications. Because official track timers do not always capture every horse, clockers provide an independent, often highly trusted set of workout times that can shape wagering decisions and a horse's perceived readiness. A second, older sense refers to someone who records employees' hours on a time clock in factories or other workplaces. The word derives simply from 'clock,' used as a verb meaning to time or record the duration of something. Informal in register, 'clocker' appears mainly in trade journalism, racing commentary, and labor history rather than everyday conversation.
A person who times and records performances or durations, especially one who times racehorses' workouts at a racetrack.
"Track clockers timed the filly's six-furlong breeze in a blistering 1:11 flat."
In horse racing, clockers are typically independent professionals rather than track employees, and their figures are widely used by handicappers.
A person who records working hours, especially one who operates or oversees a time clock at a workplace.
"As the plant's clocker, she kept careful records of every shift change."
This older industrial sense has largely faded as automated timekeeping replaced manual clocking-in.
Regular plural, standard in both senses of the word.
"Several clockers lined the rail before dawn to time the Derby hopefuls."
In horse racing, the sharpest eyes at the track belong not to trainers but to clockers — unofficial timers whose stopwatches can make or break betting odds.

Etymology of clocker
Clocker is formed by adding the agent suffix '-er' to the verb 'clock,' meaning to time or register the duration of something, which itself comes from the noun 'clock.' The noun 'clock' entered English in the late Middle Ages (14th century), probably via Dutch or Middle Low German 'klocke' from medieval Latin 'clocca' — a bell — which was also borrowed into Romance languages (French 'cloche'). The word ultimately echoes the Celtic root behind Irish 'clog' (bell). As mechanical timekeeping spread, 'clock' gave rise to related terms including 'clockwork,' 'clockwise,' and the phrase 'o'clock,' all sharing this same bell-derived ancestry.

How clocker is actually used
Informal to semi-technical. The horse-racing sense is well established in American racing circles, where clockers are respected figures whose timings inform handicappers; the workplace sense (someone who monitors or records time-clock entries) is older and less common today. Neither sense is used in formal writing.
