Measuring or recording time or speed, often using a clock or stopwatch; also can mean noticing or watching something.
From 'clock,' which comes from Middle Dutch 'clocke' (bell), since early clocks were bell-based. The verb developed in the 1700s as mechanical timekeeping became common.
In sports, 'clocking' speeds became essential once electronic timing replaced human judgment—now athletes know their exact speed down to hundredths of a second, which completely changed how we train!
