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 org.apache.commons.lang3.time.StopWatch.

The time package contains some basic utilities for manipulating time (a delorean, police box and grandfather clock?). These include a org.apache.commons.lang3.time.StopWatch for simple performance measurements and an optimized org.apache.commons.lang3.time.FastDateFormat class.
