### About

The [date](https://github.com/HowardHinnant/date) library by Howard Hinnant

offers extensive date and time functionality for the C++11, C++14 and C++17

standards.  A slighly modified version of `date.h` has been accepted (along

with `tz.h`) as part of C++20.

This package regroups all header files from the upstream repository by Howard

Hinnant so that other R packages can use them in their C++ code.

### Example

There is _a lot_ of functionality in this library.  As a teaser, consider these three

compile-time instantiations of `year_month_day` types:

```c++

  constexpr auto x1 = 2015_y/March/22;

  constexpr auto x2 = March/22/2015;

  constexpr auto x3 = 22_d/March/2015;

```

See the file [inst/examples/year_month_day.cpp](inst/examples/year_month_day.cpp) for

the complete example, and the upstream documentation for full details.

### Limitations

The `tz.h` header requires compiled support from

[`tz.cpp`](https://github.com/HowardHinnant/date/blob/master/src/tz.cpp)

which is not currently included so that this remains a header-only library.
