Changes in version 1.1.5 - Add testthat::skip_on_cran() to the tests to aid the errors from devel linux and devel windows which I am unable to reproduce. This is to retain the package on CRAN. Changes in version 1.1.3 - Minor changes in vignette. Changes in version 1.1.2 (2021-04-15) - Replace Travis and AppVeyor with GitHub Actions. - Added notes to the documentation about using lubridate::ymd_hms(). Changes in version 1.1.0 (2021-01-10) - Added a NEWS.md file to track changes to the package. - Added a protective step in midnight_to_midnight to protect from errors coming from providing a function with base::as.POSIXct()-generated timestamp (not ok) instead of lubridate::ymd_hms()-generated timestamp.
