late 14c., clokke, originally “clock with bells,” probably from Middle Dutch clocke (Dutch klok) “a clock,” from Old North French cloque (Old French cloke, Modern French cloche), from Medieval Latin (7c.) clocca “bell,” probably from Celtic (cf. Old Irish clocc, Welsh cloch, Manx clagg “a bell”) and spread by Irish missionaries (unless the Celtic words are from Latin); ultimately of imitative origin.
Replaced Old English dægmæl, from dæg “day” + mæl “measure, mark” (see meal (n.1)). The Latin word was horologium; the Greeks used a water-clock (klepsydra, literally “water thief”). Image of put (or set) the clock back “return to an earlier state or system” is from 1862. Round-the-clock (adj.) is from 1943, originally in reference to bomber air raids.
“ornament pattern on a stocking,” 1520s, probably identical with clock (n.1) in its older sense and meaning “bell-shaped ornament.”
“to time by the clock,” 1883, from clock (n.1). The slang sense of “hit, sock” is 1941, originally Australian, probably from earlier slang clock (n.) “face” (1923). Related: Clocked; clocking.
To hit; sock: who clocked me when I wasn’t looking/ She clocked him with the portable telephone (1920s+ Australian)

[first sense probably related to clock, ”face”]
A circuit in a processor that generates a regular sequence of electronic pulses used to synchronise operations of the processor’s components. The time between pulses is the cycle time and the number of pulses per second is the clock rate (or frequency).
The execution times of instructions on a computer are usually measured by a number of clock cycles rather than seconds. Clock rates for various models of the computer may increase as technology improves, and it is usually the relative times one is interested in when discussing the instruction set.
