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
