Fake timers

Fake timers are synchronous implementations of setTimeout and friends that Sinon.JS can overwrite the global functions with to allow you to more easily test code using them. It also has utilities for working with async/Promise code.

Fake timers provide a clock object to pass time, which can also be used to control Date objects (e.g. new Date()) and the Temporal API (e.g. Temporal.Now.instant()).

For standalone usage of fake timers it is recommended to use fake-timers package instead. It provides the same set of features (Sinon uses it under the hood) and was previously extracted from Sinon.JS.
