Chronometry [a] or horology [b] (lit. ' the study of time ' ) is the science studying the measurement of time and timekeeping . [ 3 ] Chronometry enables the establishment of standard measurements of time, which have applications in a broad range of social and scientific areas.
Chronology (from Latin chronologia, from Ancient Greek χρόνος, chrónos, ' time '; and -λογία, -logia) [2] is the science of arranging events in their order of occurrence in time. Consider, for example, the use of a timeline or sequence of events .

Metric time is the measure of time intervals using the metric system.The modern SI system defines the second as the base unit of time, and forms multiples and submultiples with metric prefixes such as kiloseconds and milliseconds.

chronology, an ordered sequence of events in the past. Chronologies can be put into chronological groups (periodization). One of the most important systems of periodization is the geologic time scale, which is a system of periodizing the events that shaped the Earth and its life.
It was the first type of regulator in horology. [6] A verge, or vertical shaft, is forced to rotate by a weight-driven crown wheel, but is stopped from rotating freely by a foliot. The foliot, which cannot vibrate freely, swings back and forth, which allows a wheel to rotate one tooth at a time.
