The fully-featured "even I couldn't understand that" time parser.
Designed to take in strings and give back sensible dates and times.

dtparse has its foundations in the [`dateutil`](dateutil) library for
Python, which excels at taking "interesting" strings and trying to make
sense of the dates and times they contain. A couple of quick examples
from the test cases should give some context:

```rust
extern crate chrono;
extern crate dtparse;
use chrono::prelude::*;
use dtparse::parse;

assert_eq!(
    parse("2008.12.30"),
    Ok((NaiveDate::from_ymd(2008, 12, 30).and_hms(0, 0, 0), None))
);

// It can even handle timezones!
assert_eq!(
    parse("January 4, 2024; 18:30:04 +02:00"),
    Ok((
        NaiveDate::from_ymd(2024, 1, 4).and_hms(18, 30, 4),
        Some(FixedOffset::east(7200))
    ))
);
```

And we can even handle fuzzy strings where dates/times aren't the
only content if we dig into the implementation a bit!

```rust
extern crate chrono;
extern crate dtparse;
use chrono::prelude::*;
use dtparse::Parser;
use std::collections::HashMap;

let mut p = Parser::default();
assert_eq!(
    p.parse(
        "I first released this library on the 17th of June, 2018.",
        None, None,
        true /* turns on fuzzy mode */,
        true /* gives us the tokens that weren't recognized */,
        None, false, &HashMap::new()
    ),
    Ok((
        NaiveDate::from_ymd(2018, 6, 17).and_hms(0, 0, 0),
        None,
        Some(vec!["I first released this library on the ",
                  " of ", ", "].iter().map(|&s| s.into()).collect())
    ))
);
```
