+Rust-chrono
+===========

+[![Rust-chrono on Travis CI][travis-image]][travis]
+
+[travis-image]: https://travis-ci.org/lifthrasiir/rust-chrono.png
+[travis]: https://travis-ci.org/lifthrasiir/rust-chrono
+
+Date and time handling for Rust.
+
+Design Goals
+------------
+
+* 1-to-1 correspondence with ISO 8601.
+* Timezone-aware by default.
+* Space efficient.
+* Moderate lookup table size, should not exceed a few KBs.
+* Avoid divisions as long as possible.
+
+References

+* https://github.com/mozilla/rust/wiki/Lib-datetime
