Bug fixes

lubridate#1122 Implement force_tz fallback for GMT on system where GMT is missing in zoneinfo.
lubridate#1114 Fix rounding of infinite times
Fix %ld compile printf compiler warning

Breaking Changes

For consistency reasons time_round() no longer fallbacks on round.POSIXct(). This affects only rounding on repeated DST transitions. By default timechange rounding operates on clock time, but round.POSIXct() operates on absolute time. For old behavior use absolute units (asecs, amins, ahours, etc).

New Features

#22 Implement absolute units aminute and ahour
#23 Implement new roll_dst parameters xfirst and xlast to allow for directional crossing of the DST gap
Rounding gain new origin parameter with respect to which to round with “absolute” units.

Bug Fixes

#16 Rounding unit parser is now conformant to R numeric parser
#23 Respect tzone attributes of Date objects.

Internals

#17 Simplified and refactored unit parser.

Changes

Follow vctrs replication rules
Change arguments of time_add() and time_subtract() to singulars
Build on top of cpp11 instead of Rcpp

New Features:

Refactor roll_month and roll_dst parameterisation
- more intuitive names
- full control over the behavior of repeated and skipped DST intervals
time_update() gains new argument exact = FALSE in order to enforce very strict updating rules

New Features:

New function time_get() for extraction of date-time components

Bug Fixes:

#8 Correctly handle infinite date-times

Changes:

Rename global option “week_start” -> “timechange.week_start”
