A rust library for parsing date strings in commonly used formats. Parsed date will be returned as `chrono`'s
`DateTime<Utc>`.

## Examples

Add to your `Cargo.toml`:

```toml
[dependencies]
dateparser = "0.2.1"
```

And then use `dateparser` in your code:

```rust
use dateparser::parse;
use std::error::Error;

fn main() -> Result<(), Box<dyn Error>> {
    let parsed = parse("6:15pm")?;
    println!("{:#?}", parsed);
    Ok(())
}
```

Or use `str`'s `parse` method:

```rust
use dateparser::DateTimeUtc;
use std::error::Error;

fn main() -> Result<(), Box<dyn Error>> {
    let parsed = "2021-05-14 18:51 PDT".parse::<DateTimeUtc>()?.0;
    println!("{:#?}", parsed);
    Ok(())
}
```

Convert returned `DateTime<Utc>` to pacific time zone datetime with `chrono-tz`:

```toml
[dependencies]
chrono-tz = "0.6.3"
dateparser = "0.2.1"
```

```rust
use chrono_tz::US::Pacific;
use dateparser::DateTimeUtc;
use std::error::Error;

fn main() -> Result<(), Box<dyn Error>> {
    let parsed = "Wed, 02 Jun 2021 06:31:39 GMT".parse::<DateTimeUtc>()?.0;
    println!("{:#?}", parsed.with_timezone(&Pacific));
    Ok(())
}
```

Parse using a custom timezone offset for a datetime string that doesn't come with a specific timezone:

```rust
use dateparser::parse_with_timezone;
use chrono::offset::{Local, Utc};
use chrono_tz::US::Pacific;
use std::error::Error;

fn main() -> Result<(), Box<dyn Error>> {
    let parsed_in_local = parse_with_timezone("6:15pm", &Local)?;
    println!("{:#?}", parsed_in_local);

    let parsed_in_utc = parse_with_timezone("6:15pm", &Utc)?;
    println!("{:#?}", parsed_in_utc);

    let parsed_in_pacific = parse_with_timezone("6:15pm", &Pacific)?;
    println!("{:#?}", parsed_in_pacific);

    Ok(())
}
```

Parse with a custom timezone offset and default time when those are not given in datetime string.
By default, `parse` and `parse_with_timezone` uses `Utc::now().time()` as `default_time`.

```rust
use dateparser::parse_with;
use chrono::{
    offset::{Local, Utc},
    naive::NaiveTime,
};
use std::error::Error;

fn main() -> Result<(), Box<dyn Error>> {
    let parsed_in_local = parse_with("2021-10-09", &Local, NaiveTime::from_hms(0, 0, 0))?;
    println!("{:#?}", parsed_in_local);

    let parsed_in_utc = parse_with("2021-10-09", &Utc, NaiveTime::from_hms(0, 0, 0))?;
    println!("{:#?}", parsed_in_utc);

    Ok(())
}
```
