Another (minor) nanotime release, now at version 0.3.5, just arrived at CRAN. It follows the updates RDieHarder 0.2.3 and RcppCCTZ 0.2.10 earlier today in bringing a patch kindly prepared by Tomas Kalibera for the upcoming (and very useful) ‘UCRT’ changes for Windows involving small build changes for the updated Windows toolchain.
nanotime relies on the RcppCCTZ package for (efficient) high(er) resolution time parsing and formatting up to nanosecond resolution, and the bit64 package for the actual integer64 arithmetic. Initially implemented using the S3 system, it has benefitted greatly from a rigorous refactoring by Leonardo who not only rejigged nanotime internals in S4 but also added new S4 types for periods, intervals and durations.
The NEWS snippet adds more details.
Changes in version 0.3.5 (2021-12-14)
- Applied patch by Tomas Kalibera for Windows UCRT under the upcoming R 4.2.0 expected for April.
Thanks to my CRANberries there is also a diff to the previous version. More details and examples are at the nanotime page; code, issue tickets etc at the GitHub repository.

A new release 0.2.10 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. And while CCTZ is made by Google(rs), it is not an official Google product. The RcppCCTZ page has a few usage examples and details. This package was the first CRAN package to use CCTZ; by now four others packages include its sources too. Not ideal, but beyond our control.
This version switches to r-ci, and just like RDieHarder includes a patch kindly prepared by Tomas Kalibera for the upcoming (and very useful) ‘UCRT’ changes for Windows involving small build changes for the updated Windows toolchain.

An new version 0.2.3 of the random-number generator tester RDieHarder (based on the DieHarder suite developed / maintained by Robert Brown with contributions by David Bauer and myself) is now on CRAN.
This release comes only about one and half months after the previous release 0.2.2 and is once again related to R and CRAN changes. The upcoming (and very useful) ‘UCRT’ changes for Windows involve small build changes for the updated Windows toolchain so this release includes a patch kindly prepared by Tomas Kalibera. And because compilers get cleverer and cleverer over time, I also address a warning and error found by the newest gcc in what is otherwise unchanged and years old C code … In addition, two other warnings were fixed right after the previous release.
Thanks to CRANberries, you can also look at the most recent diff.
