The ISO 8601 format includes both "nominal" (year, month, week, and
day) and "accurate" (hour, minute, and second) components. However, the
`Duration` type only represents an "accurate" duration because
arithmetic with nominal components is not defined in ISO 8601.
- Serde 0.8 is now supported. (#86)
- The deserialization implementation for rustc-serialize now properly
verifies the input. Also tons of tests have been added. (#42)
- Tons of documentation updates! (#77, #78, #80, #82 and my own
changes as well)
- `DateTime::timestamp_subsec_{millis,micros,nanos}` methods have
been added. (#81)
- When the system time records a leap second,
the nanosecond component was mistakenly reset to zero. (#84)
- `Local` offset misbehaves in Windows for August and later,
due to the long-standing libtime bug (dates back to mid-2015).
Workaround has been implemented. (#85)
- The main documentation (`src/lib.rs` AND `README.md`) now properly
link to other types when rendered.
- The role of `TimeZone` trait is explained more thoroughly.
(Hopefully) fixes#82.
- `%.6f` and `%.9f` used to print only three digits
when the nanosecond part is zero. (#71)
- The documentation for `%+` has been updated
to reflect the current status. (#71)
- Added `%.3f`, `%.6f` and `%.9f` specifier for formatting fractional seconds
up to 3, 6 or 9 decimal digits. This is a natural extension to the existing `%f`.
Note that this is (not yet) generic, no other value of precision is supported. (#45)
- Forbade unsized types from implementing `Datelike` and `Timelike`.
This does not make a big harm as any type implementing them should be already sized
to be practical, but this change still can break highly generic codes. (#46)
- Fixed a broken link in the `README.md`. (#41)
- Tons of supporting examples for the documentation have been added. More to come.

```
...because of:
https://github.com/rust-lang/rfcs/pull/1214
- Added padding modifiers `%_?`, `%-?` and `%0?`.
- Added new specifiers `%:z` and `%.f`.
- When `%s` specifier is used with a time zone, the time zone offset was
ignored. This has been fixed.
- Several documentation fixes including the misleading presence of
colons in the `%z` specifier. `%:z` was introduced partly due to this.
- `NaiveDateTime +/- Duration` or `NaiveTime +/- Duration` could
have gone wrong when the `Duration` to be added is negative and
has a fractional second part.
This was caused by an underflow in the conversion from `Duration`
to the parts; the lack of tests for this case allowed a bug.
A regression test has been added to avoid further bugs. (#37)
- This version is finally beta-compatible.
This introduces a slight incompatibility, namely, due to
the rewired reexport for `chrono::Duration` (which now comes
from crates.io `time` crate).
- The optional dependency on `rustc_serialize` and relevant
`Rustc{En,De}codable` implementations for supported types
has been added. You will need the `rustc-serialize` Cargo
feature to use them.
- Many `std::num` traits are removed and replaced with
the external `num` crate. For time being, thus, Chrono will
require the dependency on `num`. This is expected to be temporary
however.
- Replaced `thread::scoped` with `thread::spawn` to cope with
a rare de-stabilization event.
- `#[deprecated]` is (ironically) deprecated with user crates.
All uses of them have been replaced by doc comments.
- Feature flags are now required on the doctests.
- New lints for trivial casts. We are now not going to change
the internal implementation type for `NaiveDate`, so that's fine.
- `DateTime<Tz>` and `Date<Tz>` is now `Copy`/`Send` when
`Tz::Offset` is `Copy`/`Send`. The implementations for them were
mistakenly omitted. Fixes#25.
- `Local::from_utc_datetime` didn't set a correct offset.
The tests for `Local` were lacking. Fixes#26.
`Time` with an associated time zone is in principle possible, but
in practice it can only meaningfully constructed from an existing
`DateTime`. this makes it hard to implement other operations
natural to `NaiveTime` for `Time` (e.g. `with_*` methods), so
we simply let it go.
migration path: if you *do* happen to use `Time`, don't panic!
every operation possible to `Time` is much more possible to
`NaiveTime`. if you have to deal with a local time, first combine
it with a `NaiveDate`, convert it via `TimeZone::from_local_datetime`
then extract `Time` part again.
- We have splitted `Offset` into `Offset` and `OffsetState` (name
changes in consideration). The former is used to construct and convert
local or UTC date, and the latter is used to store the UTC offset
inside constructed values. Some offsets are their own states as well.
- This uses lots of associated types which implementation is still in
flux. Currently it crashes with debuginfo enabled. We've temporarily
disabled debuginfo from `Cargo.toml`.
- This technically allows a conversion to the local time, but not yet
tested.
so that we can safely implement `FromStr` traits for those types.
also updates READMEs and rewires `%+` specifier of `StrftimeItems`
to a new RFC 3339 formatting item.
this new module encompasses John Nagle's original RFC 2822 and 3337
parsers, updated to fully compatible to the actual standard.
the contributed `parse` module has been merged into it.
Basically, this should close#12 when officially released.
- Formatting syntax is now refactored out of the rendering logic.
The main syntax is available in the `format::strftime` module,
which also serves as a documentation for the syntax.
- A parser (modelled after `strptime(3)`) has been implemented.
See the individual commits for the detailed implementation.
- There are two ways to get a timezone-aware value from a string:
`Offset` or `DateTime<FixedOffset>`. The former should be used
when the offset is known in advance (e.g. assume the local date)
while the latter should be used when the offset is unknown.
Naive types have a simple `from_str` method.
- There are some known problems with the parser (even after
tons of tests), which will be sorted out in 0.2. Known issues:
- This does not exactly handle RFC 2822 and RFC 3339, which
subtly differs from the current implementation in
case-sensitivity, whitespace handling and legacy syntax.
I'd like to integrate #24 for this cause.
- Time zone names are not recognized at all. There is even
no means to get a name itself, not sure about the resolution.
- `Parsed` does *not* constrain `year` to be non-negative,
so manually prepared `Parsed` may give a negative year.
But the current verification pass may break such cases.
- I absolutely don't know about the parser's performance!
- `AUTHORS.txt` has been added, for what it's worth.
- Every type modulo `LocalResult` and `Offset` now implements
`std::fmt::String`, so `.to_string()` can be used.
The exact format has been changed for better looking output.
- `std::fmt::Show` are intended for "stricter" output,
which mostly means the strict ISO 8601 format.
`DelayedFormat` also implements this, but only for inspection.
- `Offset` should implement `Show` but can omit `String`.
The old `name` method is merged into `String` implementations.
- Feature flags used are all accepted.
- Orphan check workaround is no longer required.
- Impl reachability rules prevent the addition of `Duration + others`,
as `Duration` is not implemented in this crate. Removed the impl;
use `others + Duration` as a workaround.
- #[deriving] is now #[derive].
- prelude no longer imports many items by default.
- [T, ..n] is no longer valid.
- a temporary fix for #[derive(Hash)] failing out.
- the formatting error uses a dedicated type instead of `IoError`.
Added 'use' statements for cmd::Ordering, ops::{Add, Sub}, borrow::IntoCow, num::ToPrimitive
Changed deriving -> derive. Changed [x, ..N] -> [x; N].
Made format(f: &fmt::Formatter) return fmt::Result instead of
IoResult. Had to raise generic errors in a couple of cases where
IoResult's fields were being set (but these errors were being thrown
out anyway).
Temporarily set #![feature(old_orphan_check)] because
Thanks for @eddyb for explaining the format() situation.
- `Date/Time - Duration` is now supported. (duh!)
- `with_offset` methods have been added.
- `LocalResult` now implements common traits.
- `LocalResult` has several methods to propagate errors.
this makes the initialization from untrusted sources easier
(`off.ymd_opt(y,m,d).and_hms_opt(h,n,s).single()`).
- `num` dependency is gone. It was only used for floored division
and it is not hard to copy only that portion from num.
- `Duration + Date` (or so) was blocked by rust-lang/rust#7590,
which has been subsequently fixed.
- Removed unused `unsafe` checks.
- `std::fmt::WriteError` is now `std::fmt::Error`.
- abandoned rust-ci for documentations (sorry, but it didn't work
nowdays ;_;), we are now publishing directly to Github pages.
the minimum and maximum for `DateZ` and `Duration` is now provided via
dedicated constants `{date,duration}::{MIN,MAX}`, much like built-in
`std::int` and others. they also now implements `std::num::Bounded`.
cf. rust-lang/rust#15934
- added a new example.
- reexported all public APIs in the crate root.
- made all constructors fail on the invalid arguments by default;
`*_opt()` variants have been added for the original behavior.
- same for `DateZ::{succ,pred}`.
- fixed a missing overflow check from `TimeZ::from_hms_{milli,micro}`.
