* Add functions to get milli/micro/nano-seconds from a DateTime
Using the underlying naive::NaiveTime fractional part, we compute
the number of milli/micro/nano-seconds since the last second boundary.
The reason for not computing elapsed time since 1970 is because we
would hit potential issues of i64s not being large enough (the range
would be strictly smaller than the 64bit-timestamp range, causing
compatibility issues).
* Rename subsecond functions
Renamed accessors to subsec_{nano,micro,milli}, as suggested
in pull request comment. Also added warnings for leap second
consitions causing these values to exceed the normal range
of 0..10^n.
Fixed editor's previous obnoxious whitespace changes.
• Make what Duration is the first thing mentioned instead of project history.
• Add "magnitude" to the description to disambiguate it from Interval (in the Joda sense).
• Brush up some awkward language.
• Add a doc link and illustrate the module namespace.
- `%.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.
