anytime 0.1.0: New features, some fixes

November 7, 2016

A new release of anytime is now on CRAN following the four releases in September and October.

anytime aims to convert anything in integer, numeric, character, factor, ordered, … format to POSIXct (or Date) objects — and does so without requiring a format string. See the anytime page for a few examples.

Release 0.1.0 adds several new features. New functions utctime() and utcdate() parse to coordinated universal time (UTC). Several new formats were added. Digit-only formats like ‘YYYYMMDD’ with or without ‘HHMMSS’ (or even with fractional secodns ‘HHMMSS.ffffff’) are supported more thoroughly. Some examples:

R> library(anytime)
R> anytime("20161107 202122")   ## all digits
[1] "2016-11-07 20:21:22 CST"
R> utctime("2016Nov07 202122")  ## UTC parse example
[1] "2016-11-07 14:21:22 CST"

The NEWS file summarises the release:

Changes in anytime version 0.1.0 (2016-11-06)

  • New functions utctime() and utcdate() were added to parse input as coordinated universal time; the functionality is also available in anytime() and anydate() via a new argument asUTC (PR #22)

  • New (date)time format for RFC822-alike dates, and expanded existing datetime formats to all support fractional seconds (PR #21)

  • Extended functionality to support not only ‘YYYYMMDD’ (without a separator, and not covered by Boost) but also with ‘HHMM’, ‘HHMMSS’ and ‘HHMMSS.ffffff’ (PR #30 fixing issue #29)

  • Extended functionality to support ‘HHMMSS[.ffffff]’ following other date formats.

  • Documentation and tests have been expanded; typos corrected

  • New (unexported) helper functions setTZ, testOutput, setDebug

  • The testFormat (and testOutput) functions cannot be called under RStudio (PR #27 fixing issue #25).

  • More robust support for non-finite values such as NA, NaN or Inf (Fixing issue #16)
