Pronunciation: klǒk
n.1.A machine for measuring time, indicating the hour and other divisions; in ordinary mechanical clocks for domestic or office use the time is indicated on a typically circular face or dial plate containing two hands, pointing to numbers engraved on the periphery of the face, thus showing the hours and minutes. The works of a mechanical clock are moved by a weight or a spring, and it is often so constructed as to tell the hour by the stroke of a hammer on a bell. In electrical or electronic clocks, the time may be indicated, as on a mechanical clock, by hands, but may also be indicated by direct digital readout, with the hours and minutes in normal Arabic numerals. The readout using hands is often called analog to distinguish it from the digital readout. Some clocks also indicate the seconds. Clocks are not adapted, like the watch, to be carried on the person. Specialized clocks, such as atomic clocks, may be constructed on different principles, and may have a very high precision for use in scientific observations.
2.A watch, esp. one that strikes.
3.The striking of a clock.
4.A figure or figured work on the ankle or side of a stocking.
Alarm clock
See under Alarm.
Astronomical clock
a - A clock of superior construction, with a compensating pendulum, etc., to measure time with great accuracy, for use in astronomical observatories; - called a regulator when used by watchmakers as a standard for regulating timepieces.
b - A clock with mechanism for indicating certain astronomical phenomena, as the phases of the moon, position of the sun in the ecliptic, equation of time, etc.
Electric clock
a - A clock moved or regulated by electricity or electro-magnetism.
b - A clock connected with an electro-magnetic recording apparatus.
Ship's clock
(Naut.) a clock arranged to strike from one to eight strokes, at half hourly intervals, marking the divisions of the ship's watches.
Sidereal clock
an astronomical clock regulated to keep sidereal time.
v. t.1.To ornament with figured work, as the side of a stocking.
v. t. & i.1.To call, as a hen. See Cluck.
n.1.(Zool.) A large beetle, esp. the European dung beetle (Scarabæus stercorarius).
Noun1.clock - a timepiece that shows the time of day
Verb1.clock - measure the time or duration of an event or action or the person who performs an action in a certain period of time; "he clocked the runners"
Synonyms: time
clock - A processor's clock or one cycle thereof. The relative execution times of instructions on a computer are usually measured by number of clock cycles rather than seconds. One good reason for this is that 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.
