nanotime 0.2.0

A new version of the nanotime package for working with nanosecond timestamps just arrived on CRAN.

nanotime uses 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.

Thanks to a metric ton of work by Leonardo Silvestri, the package now uses S4 classes internally allowing for greater consistency of operations on nanotime objects.

Changes in version 0.2.0 (2017-06-22)

• Rewritten in S4 to provide more robust operations (#17 by Leonardo)

• Ensure tz="" is treated as unset (Leonardo in #20)

• Added format and tz arguments to nanotime, format, print (#22 by Leonardo and Dirk)

• Ensure printing respect options()$max.print, ensure names are kept with vector (#23 by Leonardo)

• Correct summary() by defining names<- (Leonardo in #25 fixing #24)

• Report error on operations that are meaningful for type; handled NA, NaN, Inf, -Inf correctly (Leonardo in #27 fixing #26)

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.
