| Multiple HTTP header fields store timestamps. |
| For example a response created on May 15, 2015 may contain the header |
| `Date: Fri, 15 May 2015 15:34:21 GMT`. Since the timestamp does not |
| contain any timezone or leap second information it is equvivalent to |
| writing 1431696861 Unix time. Rust’s `SystemTime` is used to store |
| these timestamps. |
| |
| This crate provides two public functions: |
| |
| * `parse_http_date` to parse a HTTP datetime string to a system time |
| * `fmt_http_date` to format a system time to a IMF-fixdate |
| |
| In addition it exposes the `HttpDate` type that can be used to parse |
| and format timestamps. Convert a sytem time to `HttpDate` and vice versa. |
| The `HttpType` (8 bytes) is smaller than `SystemTime` (16 bytes) and |
| using the display impl avoids a temporary allocation. |
| |
| Read the [blog post](https://pyfisch.org/blog/http-datetime-handling/) to learn |
| more. |

| Fuzz it by installing *cargo-fuzz* and running `cargo fuzz run fuzz_target_1`. |
