### About

This package provides C-level date / datetime functionality taken from the R
sources and made available for use by other packages.

It is useful if you are writing C (or C++) code in an R package which needs
to parse, format or transform date(time) objects, and want to do this at the
compiled level, i.e. faster than calling back to the corresponding R level
function could do it.

### Installation

The package is now on [CRAN](https://cran.r-project.org) and can be installed
via a standard

```r
install.packages("RApiDatetime")
```

### Copyrights

Copyrights are held by the respective authors, in particular the R Core Team
for the included code from R, and Dirk Eddelbuettel for any modificatons,
integration and the remainder of the package.
