1950's
Millisecond, second, minute, hour, day, month, year, decade, century, millenium, eon and light year are the ones I can think of. Other unit measurers are called a pendulum, a stopwatch, a watch, a clock, a water clock, a pocketwatch, a grandfather clock, a sundial and an atomic clock.
The second hand on a clock was invented by Swiss clockmaker Jost Burgi in the late 16th century. Burgi is also credited with developing the first mechanical timepiece with a second hand.
the second hand
The mechanical clock is a medieval invention. The ancient world measured time by sundial and the water clock. Both of these were used by the Babylonians in the second millennium BC and both were improved by the Greeks.
8th century
The second hand on the clock circles 420 times in 7 hours.
The angular velocity of the second hand of a clock is pi/30 radians per second.
The pace of the system clock, called the clock speed, is measured by the number of ticks per second. The faster the clock speed, the more instruction the processor can execute per second.
The pace of the system clock measured by the number of ticks per second is called the clock speed. This refers to how many processing cycles the clock completes in one second. It is often measured in hertz (Hz).

The second hand on a clock is called the "second hand" because it measures seconds as they pass, helping to indicate the precise time.
