//! A configurable source of time. //! //! This module provides the [`now`][n] function, which returns an `Instant` //! representing "now". The source of time used by this function is configurable //! (via the [`tokio-timer`] crate) and allows mocking out the source of time in //! tests or performing caching operations to reduce the number of syscalls. //! //! Note that, because the source of time is configurable, it is possible to //! observe non-monotonic behavior when calling [`now`][n] from different //! executors. //! //! [n]: fn.now.html //!
