Chronometry (from Greek χρόνος chronos, "time" and μέτρον metron, "measure") is the science of the measurement of time, or timekeeping. Chronometry provides a standard of measurement for time, and therefore serves as a significant reference for many and various fields of science.
The importance of the accuracy and reliability of measuring time provides a standardized unit for chronometric experiments for the modern world, and more specifically scientific research. Despite the coincidental identicality of worldwide units of time, time produces a measurement of change and is a variable in many experiments. Therefore, time is an essential part of many areas of science.
