/**
* This annotation marks the experimental preview of the standard library API for measuring time and working with durations.
*
* > Note that this API is in a preview state and has a very high chance of being changed in the future.
* Do not use it if you develop a library since your library will become binary incompatible
* with the future versions of the standard library.
*
* Any usage of a declaration annotated with `@ExperimentalTime` must be accepted either by
* annotating that usage with the [OptIn] annotation, e.g. `@OptIn(ExperimentalTime::class)`,
* or by using the compiler argument `-opt-in=kotlin.time.ExperimentalTime`.
