Time deviation (TDEV), also known as , is the time stability of phase x versus observation interval τ of the measured clock source. The time deviation thus forms a standard deviation type of measurement to indicate the time instability of the signal source. This is a scaled variant of frequency stability of Allan deviation. It is commonly defined from the modified Allan deviation, but other estimators may be used. Time variance (TVAR) also known as is the time stability of phase versus observation interval tau. It is a scaled variant of modified Allan variance. TDEV is a metric often used to determine an aspect of the quality of timing signals in telecommunication applications and is a statistical analysis of the phase stability of a signal over a given period. Measurements of a reference timing signal will refer to its TDEV and maximum time interval error (MTIE) values, comparing them to specified masks or goals. (Wikipedia).

The second is the International base unit of time but how is it defined? Here is an explanation.

Time is a mystery; it's not what it seems. Time's flow feels unstoppable, yet some say time is not fundamental, perhaps not even real. Why do physicists and philosophers think time is a construct, something that emerges, not something that is basic? For more on information and video inter

How to find the number of standard deviations that it takes to represent all the data
👉 Learn how to find the variance and standard deviation of a set of data. The variance of a set of data is a measure of spread/variation which measures how far a set of numbers is spread out from their average value. The standard deviation of a set of data is a measure of spread/variation
