(time/R-lubridate) Updated 1.7.10 to 1.9.2
Version 1.9.2 ============= ### BUG FIXES * [#1104](tidyverse/lubridate#1104) Fix incorrect parsing of months when %a format is present. ### OTHER * Adapt to internal name changes in R-devel Version 1.9.1 ============= ### NEW FEATURES * `as_datetime()` accepts multiple formats in format argument, just like `as_date()` does. ### BUG FIXES * [#1091](tidyverse/lubridate#1091) Fix formatting of numeric inputs to parse_date_time. * [#1092](tidyverse/lubridate#1092) Fix regression in `ymd_hm` on locales where `p` format is not defined. * [#1097](tidyverse/lubridate#1097) Fix `as_date("character")` to work correctly with formats that include extra characters. * [#1098](tidyverse/lubridate#1098) Roll over the month boundary in `make_dateime()` when units exceed their maximal values. * [#1090](tidyverse/lubridate#1090) timechange has been moved from Depends to Imports. Version 1.9.0 ============= ### NEW FEATURES * `roll` argument to updating and time-zone manipulation functions is deprecated in favor of a new `roll_dst` parameter. * [#1042](tidyverse/lubridate#1042) `as_date` with character inputs accepts multiple formats in `format` argument. When `format` is supplied, the input string is parsed with `parse_date_time` instead of the old `strptime`. * [#1055](tidyverse/lubridate#1055) Implement `as.integer` method for Duration, Period and Interval classes. * [#1061](tidyverse/lubridate#1061) Make `year<-`, `month<-` etc. accessors truly generic. In order to make them work with arbitrary class XYZ, it's enough to define a `reclass_date.XYZ` method. * [#1061](tidyverse/lubridate#1061) Add support for `year<-`, `month<-` etc. accessors for `data.table`'s IDate and ITime objects. * [#1017](tidyverse/lubridate#1017) `week_start` argument in all lubridate functions now accepts full and abbreviated names of the days of the week. * The assignment value `wday<-` can be a string either in English or as provided by the current locale. * Date rounding functions accept a date-time `unit` argument for rounding to a vector of date-times. * [#1005](tidyverse/lubridate#1005) `as.duration` now allows for full roundtrip `duration -> as.character -> as.duration` * [#911](tidyverse/lubridate#911) C parsers treat multiple spaces as one (just like strptime does) * `stamp` gained new argument `exact=FALSE` to indicate whether `orders` argument is an exact strptime formats string or not. * [#1001](tidyverse/lubridate#1001) Add `%within` method with signature (Interval, list), which was documented but not implemented. * [#941](tidyverse/lubridate#941) `format_ISO8601()` gained a new option `usetz="Z"` to format time zones with a "Z" and convert the time to the UTC time zone. * [#931](tidyverse/lubridate#931) Usage of `Period` objects in rounding functions is explicitly documented. ### BUG FIXES * [#1036](tidyverse/lubridate#1036) `%within%` now correctly works with flipped intervals * [#1085](tidyverse/lubridate#1085) `as_datetime()` now preserves the time zone of the POSIXt input. * [#1072](tidyverse/lubridate#1072) Names are now handled correctly when combining multiple Period or Interval objects. * [#1003](tidyverse/lubridate#1003) Correctly handle r and R formats in locales which have no p format * [#1074](tidyverse/lubridate#1074) Fix concatination of named Period, Interval and Duration vectors. * [#1044](tidyverse/lubridate#1044) POSIXlt results returned by `fast_strptime()` and `parse_date_time2()` now have a recycled `isdst` field. * [#1069](tidyverse/lubridate#1069) Internal code handling the addition of period months and years no longer generates partially recycled POSIXlt objects. * Fix rounding of POSIXlt objects * [#1007](tidyverse/lubridate#1007) Internal lubridate formats are no longer propagated to stamp formater. * `train` argument in `parse_date_time` now takes effect. It was previously ignored. * [#1004](tidyverse/lubridate#1004) Fix `c.POSIXct` and `c.Date` on empty single POSIXct and Date vectors. * [#1013](tidyverse/lubridate#1013) Fix c(`POSIXct`,`POSIXlt`) heterogeneous concatenation. * [#1002](tidyverse/lubridate#1002) Parsing only with format `j` now works on numeric inputs. * `stamp()` now correctly errors when no formats could be guessed. * Updating a date with timezone (e.g. `tzs = "UTC"`) now returns a POSIXct. ### INTERNALS * `lubridate` is now relying on `timechange` package for update and time-zone computation. Google's CCTZ code is no longer part of the package. * `lubridate`'s updating logic is now built on top of `timechange` package. * Change implementation of `c.Period`, `c.Duration` and `c.Interval` from S4 to S3. Version 1.8.0 ============= ### NEW FEATURES * [#960](tidyverse/lubridate#960) `c.POSIXct` and `c.Date` can deal with heterogeneous object types (e.g `c(date, datetime)` works as expected) ### BUG FIXES * [#994](tidyverse/lubridate#994) Subtracting two duration or two period objects no longer results in an ambiguous dispatch note. * `c.Date` and `c.POSIXct` correctly deal with empty vectors. * `as_datetime(date, tz=XYZ)` returns the date-time object with HMS set to 00:00:00 in the corresponding `tz` ### CHANGES * [#966](tidyverse/lubridate#966) Lubridate is now built with cpp11 (contribution of @DavisVaughan)
