In krlmlr/hms: Pretty Time of Day

hms 0.5.2.9001

• vec_ptype2.hms.default() forwards to vec_default_ptype2() for compatibility with vctrs 0.2.1.
• Remove as.data.frame.hms(), handeld by vctrs.

hms 0.5.2.9000

• Internal changes only.

hms 0.5.2

• Work around parsing error that occurs on DST changeover dates (https://bugs.r-project.org/bugzilla/show_bug.cgi?id=16764).

hms 0.5.1

• Lossy casts from character vectors to hms now also trigger a warning if the cast succeeds in the first element of the vector but fails for other elements.

hms 0.5.0

Breaking changes

• Now based on vctrs >= 0.2.0 (#61). This adds support for vec_cast() and vec_ptype2(). Some operations (such as subset assignment) are now stricter. The new_hms() constructor permits safe construction of hms objects from a numeric vector.

• The new is_hms() deprecates the existing is.hms(). as.hms() is deprecated in favor of vec_cast() or the new as_hms() (which is just a thin wrapper around vec_cast()).

Printing

• Always show seconds in a pillar if they are different from zero (#54).

• Values with nonzero hours, seconds and split-seconds are now displayed correctly in tibbles (#56), even with a very small distance to the full second (#64).

Internal

• Don't test colored output on CRAN.
• Correct reference link on r4ds (#58, @evanhaldane).

hms 0.4.2

• Adapted tests to pillar 1.2.1.

hms 0.4.1

• Preserve NA when converting to character (#51, @jeroen).
• Adapted tests to pillar 1.1.0.

hms 0.4.0

Breaking changes

• as.hms.POSIXt() now defaults to the current time zone, the previous default was "UTC" and can be restored by calling pkgconfig::set_config("hms::default_tz", "UTC").

New features

• Pillar support, will display hms columns in tibbles in color on terminals that support it (#43).
• New round_hms() and trunc_hms() for rounding or truncating to a given multiple of seconds (#31).
• New parse_hms() and parse_hm() to parse strings in "HH:MM:SS" and "HH:MM" formats (#30).
• as.hms.POSIXt() gains tz argument, default "UTC" (#28).
• as.hms.character() and parse_hms() accept fractional seconds (#33).

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

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

hms 0.2

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

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)
