Package org.apache.commons.lang3.time

Provides classes and methods to work with dates and durations. These classes are immutable (and therefore thread-safe) apart from StopWatch.

The time package contains some basic utilities for manipulating time (a delorean, police box and grandfather clock?). These include a StopWatch for simple performance measurements and an optimised FastDateFormat class.

New in Lang 2.1 is the DurationFormatUtils class, which provides various methods for formatting durations.
