//!
//! It aims to be a feature-complete superset of
//! the [time](https://github.com/rust-lang-deprecated/time) library.
//! In particular,
//!
//! * Chrono strictly adheres to ISO 8601.
//! * Chrono is timezone-aware by default, with separate timezone-naive types.
//! * Chrono is space-optimal and (while not being the primary goal) reasonably efficient.
//!
//! There were several previous attempts to bring a good date and time library to Rust,
//! which Chrono builds upon and should acknowledge:
//!
//! * [Initial research on
//! the wiki](https://github.com/rust-lang/rust-wiki-backup/blob/master/Lib-datetime.md)
//! * Dietrich Epp&#39;s [datetime-rs](https://github.com/depp/datetime-rs)
//! * Luis de Bethencourt&#39;s [rust-datetime](https://github.com/luisbg/rust-datetime)
//!
//! ### Features
//!
//! Chrono supports various runtime environments and operating systems, and has
//! several features that may be enabled or disabled.
//!
//! Default features:
//!
//! - `alloc`: Enable features that depend on allocation (primarily string formatting)
//! - `std`: Enables functionality that depends on the standard library. This
//! is a superset of `alloc` and adds interoperation with standard library types
//! and traits.
//! - `clock`: Enables reading the system time (`now`) that depends on the standard library for
//! UNIX-like operating systems and the Windows API (`winapi`) for Windows.
//!
//! Optional features:
//!
//! - [`serde`][]: Enable serialization/deserialization via serde.
//! - `unstable-locales`: Enable localization. This adds various methods with a
//! `_localized` suffix. The implementation and API may change or even be
//! removed in a patch release. Feedback welcome.
//!
//! [`serde`]: https://github.com/serde-rs/serde
//! [wasm-bindgen]: https://github.com/rustwasm/wasm-bindgen
//!
//! See the [cargo docs][] for examples of specifying features.
//!
//! [cargo docs]: https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#choosing-features
//!
//! ## Overview
//!
//! ### Duration
//!
//! Chrono currently uses its own [`Duration`] type to represent the magnitude
//! of a time span. Since this has the same name as the newer, standard type for
//! duration, the reference will refer this type as `OldDuration`.
//!
//! Note that this is an &quot;accurate&quot; duration represented as seconds and
//! nanoseconds and does not represent &quot;nominal&quot; components such as days or
//! months.
//!
//! When the `oldtime` feature is enabled, [`Duration`] is an alias for the
//! [`time::Duration`](https://docs.rs/time/0.1.40/time/struct.Duration.html)
//! type from v0.1 of the time crate. time v0.1 is deprecated, so new code
//! should disable the `oldtime` feature and use the `chrono::Duration` type
//! instead. The `oldtime` feature is enabled by default for backwards
//! compatibility, but future versions of Chrono are likely to remove the
//! feature entirely.
//!
//! Chrono does not yet natively support
//! the standard [`Duration`](https://doc.rust-lang.org/std/time/struct.Duration.html) type,
//! but it will be supported in the future.
//! Meanwhile you can convert between two types with
//! [`Duration::from_std`](https://docs.rs/time/0.1.40/time/struct.Duration.html#method.from_std)
//! and
//! [`Duration::to_std`](https://docs.rs/time/0.1.40/time/struct.Duration.html#method.to_std)
//! methods.
//!
//! ### Date and Time
//!
//! Chrono provides a
//! [**`DateTime`**](./struct.DateTime.html)
//! type to represent a date and a time in a timezone.
//!
//! For more abstract moment-in-time tracking such as internal timekeeping
//! that is unconcerned with timezones, consider
//! [`time::SystemTime`](https://doc.rust-lang.org/std/time/struct.SystemTime.html),
//! which tracks your system clock, or
//! [`time::Instant`](https://doc.rust-lang.org/std/time/struct.Instant.html), which
//! is an opaque but monotonically-increasing representation of a moment in time.
//!
//! `DateTime` is timezone-aware and must be constructed from
//! the [**`TimeZone`**](./offset/trait.TimeZone.html) object,
//! which defines how the local date is converted to and back from the UTC date.
//! There are three well-known `TimeZone` implementations:
//!
//! * [**`Utc`**](./offset/struct.Utc.html) specifies the UTC time zone. It is most efficient.
//!
//! * [**`Local`**](./offset/struct.Local.html) specifies the system local time zone.
//!
//! * [**`FixedOffset`**](./offset/struct.FixedOffset.html) specifies
//! an arbitrary, fixed time zone such as UTC+09:00 or UTC-10:30.
//! This often results from the parsed textual date and time.
//! Since it stores the most information and does not depend on the system environment,
//! you would want to normalize other `TimeZone`s into this type.
//!
//! `DateTime`s with different `TimeZone` types are distinct and do not mix,
//! but can be converted to each other using
//! the [`DateTime::with_timezone`](./struct.DateTime.html#method.with_timezone) method.
//!
//! You can get the current date and time in the UTC time zone
//! ([`Utc::now()`](./offset/struct.Utc.html#method.now))
//! or in the local time zone
//! ([`Local::now()`](./offset/struct.Local.html#method.now)).
//!

//! Utc.with_ymd_and_hms(1938, 4, 24, 22, 13, 20).unwrap());
//! ```
//!
//! ### Formatting and Parsing
//!
//! Formatting is done via the [`format`](./struct.DateTime.html#method.format) method,
//! which format is equivalent to the familiar `strftime` format.
//!
//! See [`format::strftime`](./format/strftime/index.html#specifiers)
//! documentation for full syntax and list of specifiers.
//!
//! The default `to_string` method and `{:?}` specifier also give a reasonable representation.
//! Chrono also provides [`to_rfc2822`](./struct.DateTime.html#method.to_rfc2822) and
//! [`to_rfc3339`](./struct.DateTime.html#method.to_rfc3339) methods
//! for well-known formats.
//!
//! Chrono now also provides date formatting in almost any language without the
//! help of an additional C library. This functionality is under the feature
//! `unstable-locales`:
//!
//! ```toml
//! chrono = { version = &quot;0.4&quot;, features = [&quot;unstable-locales&quot;] }
//! ```
//!
//! The `unstable-locales` feature requires and implies at least the `alloc` feature.
//!
//! ```rust
//! # #[allow(unused_imports)]
//! use chrono::prelude::*;
//!
//! # #[cfg(feature = &quot;unstable-locales&quot;)]
//! # fn test() {
//! let dt = Utc.with_ymd_and_hms(2014, 11, 28, 12, 0, 9).unwrap();
//! assert_eq!(dt.format(&quot;%Y-%m-%d %H:%M:%S&quot;).to_string(), &quot;2014-11-28 12:00:09&quot;);
//! assert_eq!(dt.format(&quot;%a %b %e %T %Y&quot;).to_string(), &quot;Fri Nov 28 12:00:09 2014&quot;);
//! assert_eq!(dt.format_localized(&quot;%A %e %B %Y, %T&quot;, Locale::fr_BE).to_string(), &quot;vendredi 28 novembre 2014, 12:00:09&quot;);
//!
//! assert_eq!(dt.format(&quot;%a %b %e %T %Y&quot;).to_string(), dt.format(&quot;%c&quot;).to_string());
//! assert_eq!(dt.to_string(), &quot;2014-11-28 12:00:09 UTC&quot;);
//! assert_eq!(dt.to_rfc2822(), &quot;Fri, 28 Nov 2014 12:00:09 +0000&quot;);
//! assert_eq!(dt.to_rfc3339(), &quot;2014-11-28T12:00:09+00:00&quot;);
//! assert_eq!(format!(&quot;{:?}&quot;, dt), &quot;2014-11-28T12:00:09Z&quot;);
//!
//! // Note that milli/nanoseconds are only printed if they are non-zero
//! let dt_nano = NaiveDate::from_ymd_opt(2014, 11, 28).unwrap().and_hms_nano_opt(12, 0, 9, 1).unwrap().and_local_timezone(Utc).unwrap();
//! assert_eq!(format!(&quot;{:?}&quot;, dt_nano), &quot;2014-11-28T12:00:09.000000001Z&quot;);
//! # }
//! # #[cfg(not(feature = &quot;unstable-locales&quot;))]
//! # fn test() {}
//! # if cfg!(feature = &quot;unstable-locales&quot;) {
//! # test();
//! # }
//! ```
//!
//! Parsing can be done with three methods:
//!
//! 1. The standard [`FromStr`](https://doc.rust-lang.org/std/str/trait.FromStr.html) trait
//! (and [`parse`](https://doc.rust-lang.org/std/primitive.str.html#method.parse) method
//! on a string) can be used for parsing `DateTime&lt;FixedOffset&gt;`, `DateTime&lt;Utc&gt;` and
//! `DateTime&lt;Local&gt;` values. This parses what the `{:?}`
//! ([`std::fmt::Debug`](https://doc.rust-lang.org/std/fmt/trait.Debug.html))
//! format specifier prints, and requires the offset to be present.
//!
//! 2. [`DateTime::parse_from_str`](./struct.DateTime.html#method.parse_from_str) parses
//! a date and time with offsets and returns `DateTime&lt;FixedOffset&gt;`.
//! This should be used when the offset is a part of input and the caller cannot guess that.
//! It *cannot* be used when the offset can be missing.
//! [`DateTime::parse_from_rfc2822`](./struct.DateTime.html#method.parse_from_rfc2822)
//! and
//! [`DateTime::parse_from_rfc3339`](./struct.DateTime.html#method.parse_from_rfc3339)
//! are similar but for well-known formats.
//!
//! 3. [`Offset::datetime_from_str`](./offset/trait.TimeZone.html#method.datetime_from_str) is
//! similar but returns `DateTime` of given offset.
//! When the explicit offset is missing from the input, it simply uses given offset.
//! It issues an error when the input contains an explicit offset different
//! from the current offset.
//!
//! More detailed control over the parsing process is available via
//! [`format`](./format/index.html) module.
//!
//! ```rust
//! use chrono::prelude::*;
//!
//! let dt = Utc.with_ymd_and_hms(2014, 11, 28, 12, 0, 9).unwrap();
//! let fixed_dt = dt.with_timezone(&amp;FixedOffset::east_opt(9*3600).unwrap());
//!
//! // method 1
//! assert_eq!(&quot;2014-11-28T12:00:09Z&quot;.parse::&lt;DateTime&lt;Utc&gt;&gt;(), Ok(dt.clone()));
//! assert_eq!(&quot;2014-11-28T21:00:09+09:00&quot;.parse::&lt;DateTime&lt;Utc&gt;&gt;(), Ok(dt.clone()));
//! assert_eq!(&quot;2014-11-28T21:00:09+09:00&quot;.parse::&lt;DateTime&lt;FixedOffset&gt;&gt;(), Ok(fixed_dt.clone()));
//!
//! // method 2
//! assert_eq!(DateTime::parse_from_str(&quot;2014-11-28 21:00:09 +09:00&quot;, &quot;%Y-%m-%d %H:%M:%S %z&quot;),
//! Ok(fixed_dt.clone()));
//! assert_eq!(DateTime::parse_from_rfc2822(&quot;Fri, 28 Nov 2014 21:00:09 +0900&quot;),
//! Ok(fixed_dt.clone()));
//! assert_eq!(DateTime::parse_from_rfc3339(&quot;2014-11-28T21:00:09+09:00&quot;), Ok(fixed_dt.clone()));
//!
//! // method 3
//! assert_eq!(Utc.datetime_from_str(&quot;2014-11-28 12:00:09&quot;, &quot;%Y-%m-%d %H:%M:%S&quot;), Ok(dt.clone()));
//! assert_eq!(Utc.datetime_from_str(&quot;Fri Nov 28 12:00:09 2014&quot;, &quot;%a %b %e %T %Y&quot;), Ok(dt.clone()));
//!
//! // oops, the year is missing!
//! assert!(Utc.datetime_from_str(&quot;Fri Nov 28 12:00:09&quot;, &quot;%a %b %e %T %Y&quot;).is_err());
//! // oops, the format string does not include the year at all!
//! assert!(Utc.datetime_from_str(&quot;Fri Nov 28 12:00:09&quot;, &quot;%a %b %e %T&quot;).is_err());
//! // oops, the weekday is incorrect!
//! assert!(Utc.datetime_from_str(&quot;Sat Nov 28 12:00:09 2014&quot;, &quot;%a %b %e %T %Y&quot;).is_err());
//! ```
//!
//! Again : See [`format::strftime`](./format/strftime/index.html#specifiers)
//! documentation for full syntax and list of specifiers.
//!
//! ### Conversion from and to EPOCH timestamps
//!
//! Use [`Utc.timestamp(seconds, nanoseconds)`](./offset/trait.TimeZone.html#method.timestamp)
//! to construct a [`DateTime&lt;Utc&gt;`](./struct.DateTime.html) from a UNIX timestamp
//! (seconds, nanoseconds that passed since January 1st 1970).
//!
//! Use [`DateTime.timestamp`](./struct.DateTime.html#method.timestamp) to get the timestamp (in seconds)
//! from a [`DateTime`](./struct.DateTime.html). Additionally, you can use
//! [`DateTime.timestamp_subsec_nanos`](./struct.DateTime.html#method.timestamp_subsec_nanos)
//! to get the number of additional number of nanoseconds.
//!

//! // Get epoch value from a datetime:
//! let dt = DateTime::parse_from_rfc2822(&quot;Fri, 14 Jul 2017 02:40:00 +0000&quot;).unwrap();
//! assert_eq!(dt.timestamp(), 1_500_000_000);
//! ```
//!
//! ### Naive date and time
//!
//! Chrono provides naive counterparts to `Date`, (non-existent) `Time` and `DateTime`
//! as [**`NaiveDate`**](./naive/struct.NaiveDate.html),
//! [**`NaiveTime`**](./naive/struct.NaiveTime.html) and
//! [**`NaiveDateTime`**](./naive/struct.NaiveDateTime.html) respectively.
//!
//! They have almost equivalent interfaces as their timezone-aware twins,
//! but are not associated to time zones obviously and can be quite low-level.
//! They are mostly useful for building blocks for higher-level types.
//!
//! Timezone-aware `DateTime` and `Date` types have two methods returning naive versions:
//! [`naive_local`](./struct.DateTime.html#method.naive_local) returns
//! a view to the naive local time,
//! and [`naive_utc`](./struct.DateTime.html#method.naive_utc) returns
//! a view to the naive UTC time.
//!
//! ## Limitations
//!
//! Only proleptic Gregorian calendar (i.e. extended to support older dates) is supported.
//! Be very careful if you really have to deal with pre-20C dates, they can be in Julian or others.
//!
//! Date types are limited in about +/- 262,000 years from the common epoch.
//! Time types are limited in the nanosecond accuracy.
//!
//! [Leap seconds are supported in the representation but
//! Chrono doesn&#39;t try to make use of them](./naive/struct.NaiveTime.html#leap-second-handling).
//! (The main reason is that leap seconds are not really predictable.)
//! Almost *every* operation over the possible leap seconds will ignore them.
//! Consider using `NaiveDateTime` with the implicit TAI (International Atomic Time) scale
//! if you want.
//!
//! Chrono inherently does not support an inaccurate or partial date and time representation.
//! Any operation that can be ambiguous will return `None` in such cases.
//! For example, &quot;a month later&quot; of 2014-01-30 is not well-defined
//! and consequently `Utc.ymd_opt(2014, 1, 30).unwrap().with_month(2)` returns `None`.
//!
//! Non ISO week handling is not yet supported.
//! For now you can use the [chrono_ext](https://crates.io/crates/chrono_ext)
//! crate ([sources](https://github.com/bcourtine/chrono-ext/)).
//!
//! Advanced time zone handling is not yet supported.
//! For now you can try the [Chrono-tz](https://github.com/chronotope/chrono-tz/) crate instead.
