Functions to work with date-times and time-spans:
fast and user friendly parsing of date-time data, extraction and
updating of components of a date-time (years, months, days, hours,
minutes, and seconds), algebraic manipulation on date-time and
time-span objects. The 'lubridate' package has a consistent and
memorable syntax that makes working with dates easy and fun. Parts of
the 'CCTZ' source code, released under the Apache 2.0 License, are
included in this package. See <https://github.com/google/cctz> for
more details.
