<p>The first update in a little while brings us release 0.0.4 of <a rel="nofollow" href="http://dirk.eddelbuettel.com/code/rapidatetime.html" target="_blank">RApiDatetime</a> which got onto <a rel="nofollow" href="https://cran.r-project.org/" target="_blank">CRAN</a> this morning via the <em>lovely</em> automated sequence of submission, pretest-recheck and pretest-publish.</p>
<p><a rel="nofollow" href="http://dirk.eddelbuettel.com/code/rapidatetime.html" target="_blank">RApiDatetime</a> provides seven entry points for C-level functions of the R API for <code>Date</code> and <code>Datetime</code> calculations. The functions <code>asPOSIXlt</code> and <code>asPOSIXct</code> convert between long and compact datetime representation, <code>formatPOSIXlt</code> and <code>Rstrptime</code> convert to and from character strings, and <code>POSIXlt2D</code> and <code>D2POSIXlt</code> convert between <code>Date</code> and <code>POSIXlt</code> datetime. This releases brings <code>asDatePOSIXct</code> as a seventh courtesy of <a rel="nofollow" href="https://about.me/joshuaulrich" target="_blank">Josh Ulrich</a>. All these functions are all fairly useful, but not one of them was previously exported by R for C-level use by other packages. Which is silly as this is generally extremely carefully written and tested code.</p>
<p>I also updated the exported base R code to what is in R 3.5.1 right now, added a few <code>#nocov</code> declarations (not all which are reflected at the <a rel="nofollow" href="https://codecov.io/gh/eddelbuettel/rapidatetime" target="_blank">codecov page</a> yet, and added a dependency badge at the <a rel="nofollow" href="https://github.com/eddelbuettel/rapidatetime" target="_blank">GitHub repo</a>.</p>
