+Human Time
+==========
+
+**Status: stable**
+
+[Documentation](https://docs.rs/humantime) |
+[Github](https://github.com/tailhook/humantime) |
+[Crate](https://crates.io/crates/humantime)
+
+
+Features:
+
+* Parses durations in free form like `15days 2min 2s`
+* Formats durations in similar form `2years 2min 12us`
+* Parses and formats timestamp in `rfc3339` format: `2018-01-01T12:53:00Z`
+* Parses timestamps in a weaker format: `2018-01-01 12:53:00`
+
+Timestamp parsing/formatting is super-fast because format is basically
+fixed.
+
+Here are some micro-benchmarks:
+
+```

+//! Human-friendly time parser and formatter
+//!
+//! Features:
+//!
+//! * Parses durations in free form like `15days 2min 2s`
+//! * Formats durations in similar form `2years 2min 12us`
+//! * Parses and formats timestamp in `rfc3339` format: `2018-01-01T12:53:00Z`
+//! * Parses timestamps in a weaker format: `2018-01-01 12:53:00`
+//!
+//! Timestamp parsing/formatting is super-fast because format is basically
+//! fixed.
+//!
+//! See [humantime-serde] for serde integration (previous crate [serde-humantime] looks unmaintained).

+/// A wrapper for SystemTime that has `FromStr` implementation
+///
+/// This is useful if you want to use it somewhere where `FromStr` is
+/// expected.
+///
+/// See `parse_rfc3339_weak` for the description of the format. The "weak"
+/// format is used as it's more pemissive for human input as this is the
+/// expected use of the type (e.g. command-line parsing).
+///
+/// # Example
+///
+/// ```
+/// use std::time::SystemTime;
+/// let x: SystemTime;
+/// x = "2018-02-16T00:31:37Z".parse::<humantime::Timestamp>().unwrap().into();
+/// assert_eq!(humantime::format_rfc3339(x).to_string(), "2018-02-16T00:31:37Z");
+/// ```
