-/**
- * A <tt>TimeUnit</tt> represents time durations at a given unit of
- * granularity and provides utility methods to convert across units,
- * and to perform timing and delay operations in these units.  A
- * <tt>TimeUnit</tt> does not maintain time information, but only
- * helps organize and use time representations that may be maintained
- * separately across various contexts.  A nanosecond is defined as one
- * thousandth of a microsecond, a microsecond as one thousandth of a
- * millisecond, a millisecond as one thousandth of a second, a minute
- * as sixty seconds, an hour as sixty minutes, and a day as twenty four
- * hours.
- *
- * <p>A <tt>TimeUnit</tt> is mainly used to inform time-based methods
- * how a given timing parameter should be interpreted. For example,
- * the following code will timeout in 50 milliseconds if the {@link
- * java.util.concurrent.locks.Lock lock} is not available:
- *
- * <pre>  Lock lock = ...;
- *  if ( lock.tryLock(50L, TimeUnit.MILLISECONDS) ) ...
- * </pre>
- * while this code will timeout in 50 seconds:
- * <pre>
- *  Lock lock = ...;
- *  if ( lock.tryLock(50L, TimeUnit.SECONDS) ) ...
- * </pre>
- *
- * Note however, that there is no guarantee that a particular timeout
- * implementation will be able to notice the passage of time at the
- * same granularity as the given <tt>TimeUnit</tt>.
