Breaking changes

New features

Bug fixes

  • hms() now works correctly if all four components (days, hours, minutes, seconds) are passed (#49).
  • hms() creates a zero-length object of class hms that prints as "hms()".
  • hms(integer()) and as.hms(integer()) both work and are identical to hms().
  • Values with durations of over 10000 hours are now printed correctly (#48).
  • c() now returns a hms (#41, @qgeissmann).

Documentation and error messages

  • Fix and enhance examples in ?hms.
  • Documentation is in Markdown format now.
  • Improved error message if calling hms() with a character argument (#29).

hms 0.3 (2016-11-22)

  • Fix lubridate test for compatibility with 1.6.0 (#23, @vspinu).
  • NA values are formatted as NA (#22).

hms 0.2 (2016-06-17)

Minor fixes and improvements.

  • Subsetting keeps hms class (#16).
  • format.hms() right-justifies the output by padding with spaces from the left, as.character.hms() remains unchanged.
  • Times larger than 24 hours or with split seconds are now formatted correctly (#12, #13).
  • Sub-second part is printed with up to six digits, for even smaller values trailing zeros are shown (#17).

hms 0.1 (2016-04-30)

First CRAN release.

  • Values are stored as a numeric vector that contains the number of seconds since midnight.
    • Inherits from difftime class.
    • Updating units is a no-op, anything different from "secs" issues a warning.
  • Supports construction from time values, coercion to and from various data types, and formatting.
    • Conversion from numeric treats input as seconds.
    • Negative times are formatted with a leading -.
  • Can be used as a regular column in a data frame.
  • Full test coverage.
    • Test for arithmetic with Date, POSIXt and hms classes.
    • Test basic compatibility with lubridate package (#5).
  • Interface:
    • hms() (with rigorous argument checks)
    • as.hms() for character, numeric, POSIXct and POSIXlt
    • as.xxx.hms() for character, numeric (implicitly), POSIXct and POSIXlt
    • is.hms()
    • as.data.frame.hms() (forwards to as.data.frame.difftime())
    • format.hms()
    • print.hms() (returns unchanged input invisibly)
