A new version of the nanotime package for working with nanosecond timestamps is now on CRAN.

nanotime uses the RcppCCTZ package for (efficient) high(er) resolution time parsing and formatting, and the bit64 package for the actual integer64 arithmetic.

This release adds an improved default display format always showing nine digits of fractional seconds. It also changes the print() method to call format() first, and we started to provide some better default Ops methods. These fixes were suggested by Matt Dowle. We also corrected a small issue which could lead to precision loss in formatting as pointed out by Leonardo Silvestri.

Changes in version 0.1.1 (2017-02-04)

• The default display format now always shows nine digits (#10 closing #9)

• The default print method was updated to use formated output, and a new new converter as.integer64 was added

• Several ‘Ops’ method are now explicitly defined allowing casting of results (rather than falling back on bit64 behaviour)

• The format routine is now more careful about not loosing precision (#13 closing #12)

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