A parser and formatter for std::time::{Duration, SystemTime}
Documentation
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:
