RcppCCTZ 0.2.3 (and 0.2.2)

June 21, 2017

(This article was first published on Thinking inside the box , and kindly contributed to R-bloggers)

A new minor version 0.2.3 of RcppCCTZ is now on CRAN.

RcppCCTZ uses Rcpp to bring CCTZ to R. CCTZ is a C++ library for translating between absolute and civil times using the rules of a time zone. In fact, it is two libraries. One for dealing with civil time: human-readable dates and times, and one for converting between between absolute and civil times via time zones. The RcppCCTZ page has a few usage examples and details.

This version ensures that we set the TZDIR environment variable correctly on the old dreaded OS that does not come with proper timezone information—an issue which had come up while preparing the next (and awesome, trust me) release of nanotime. It also appears that I failed to blog about 0.2.2, another maintenance release, so changes for both are summarised next.

Changes in version 0.2.3 (2017-06-19)

  • On Windows, the TZDIR environment variable is now set in .onLoad()

  • Replaced init.c with registration code inside of RcppExports.cpp thanks to Rcpp 0.12.11.

Changes in version 0.2.2 (2017-04-20)

  • Synchronized with upstream CCTZ

  • The time_point object is instantiated explicitly for nanosecond use which appears to be required on macOS

We also have a diff to the previous version thanks to CRANberries. More details are at the RcppCCTZ page; code, issue tickets etc at the GitHub repository.
