- `%.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)
Although not supported directly by chrono, users should be able to
specify the RFC850 format and expect it to parse properly. RFC850 is
important since HTTP/1.1 specifies
HTTP-date = rfc1123-date | rfc850-date | asctime-date
requirement for rand comes from `num`'s default features which are all unused in `chrono`
not including the default features means that that `build` no longer requires `rand` (and hence does not pass it on to others importing `chrono`)
I thought it should also remove it for `test` / `bench` also but the `serde_json` dev-dependency seems to make it included..
- 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.
- Padding modifiers `%_?`, `%-?` and `%0?` are implemented.
They are glibc extensions which seem to be reasonably widespread
(e.g. Ruby).
- Added `%:z` specifier and corresponding formatting items
which is essentially same to `%z` but with a colon.
- Added a new specifier `%.f` which precision adapts from the input.
Also clearly documented the differences between `%f` and `%.f`. (#40)
- The time zone offset is printed without a colon, but the documentation
had that inverted. (#39)
- `chrono::format::strftime`'s specifier table is tested throughly.
- When `%s` specifier is used with a time zone, the time zone offset was
ignored. This has been fixed.
- `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)
The exact condition is that the `Duration` to be added is negative
and has a fractional second part. This was not a problem when
`Duration` was Chrono's own type, but a new code for external (then
libstd, now libtime) `Duration` was not tested for this condition
by accident. Consequently this condition caused an underflow in
the fractional part, resulting in a slight inaccuracy.
Fixes#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.
