+[![build status](https://github.com/time-rs/time/workflows/Build/badge.svg?branch=v0.1)](https://github.com/time-rs/time/actions?query=branch%3Av0.1)
+[![Documentation](https://docs.rs/time/badge.svg?version=0.1)](https://docs.rs/time/~0.1)

+
+## time v0.1.x is Deprecated
+
+The 0.1.x series of this library is deprecated and in maintenance mode. No new
+features will be added. Active development now occurs in the 0.2.x series.
+
+If you need additional functionality that this crate does not provide, check
+out the [`chrono`](https://github.com/chronotope/chrono) crate.
+
+## Usage
+
+Put this in your `Cargo.toml`:
+
+```toml
+[dependencies]
+time = "0.1"
+```
+
+And this in your crate root:
+
+```rust
+extern crate time;
+```

+//! Simple time handling.
+//!
+//! # Usage
+//!
+//! This crate is [on crates.io](https://crates.io/crates/time) and can be
+//! used by adding `time` to the dependencies in your project's `Cargo.toml`.
+//!
+//! ```toml
+//! [dependencies]
+//! time = "0.1"
+//! ```
+//!
+//! And this in your crate root:
+//!
+//! ```rust
+//! extern crate time;
+//! ```
+//!
+//! This crate uses the same syntax for format strings as the
+//! [`strftime()`](http://man7.org/linux/man-pages/man3/strftime.3.html)
+//! function from the C standard library.
