# Package groovy.time

## Package groovy.time Description

Classes for easily manipulating Dates and times. While `java.util.Date` has GDK methods for adding or subtracting days, this is not so useful for different durations of time. groovy.time.TimeCategory creates a simple internal DSL for manipulating dates and times in a clean and precise fashion.

       use (groovy.time.TimeCategory) {

           println 10.hours.ago
  TimeDatumDependentDuration | TimeDatumDuration represents a time period which results from an arithmetic operation between a TimeDuration object and a DatumDuration object
  TimeDuration | TimeDuration represents time periods expressed in units of hours, minutes, seconds and milliseconds.
