| //! 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. |
| //! |
