On this page

Scope

Date parsing, date parts, rounding, periods, time zones, and string functions. Values compared with lubridate's and stringr's.

References

Reference
R 4.6.1 with lubridate 1.9.5, stringr 1.6.0
Versions
R 4.6.1, lubridate 1.9.5, stringr 1.6.0, PHP 8.5.10, phibble v0.8.0 (9e63ca5)

Data

Inline vectors
Five dates, datetimes, and strings, including a missing value, a leap day, and a daylight-saving gap.

Method

Reference results computed in R by tests/r/lubridate_stringr.R and stored in tests/Fixtures/. The same operations run in phplyr in tests/LubridateStringrTest.php, which compare every value. Values compared is the number of assertions in a case; a case fails if any assertion fails.

Applies to: All values

Dates as YYYY-MM-DD, datetimes as YYYY-MM-DD HH:MM:SS +hhmm
