| 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. |
| 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 <CODE>lock</CODE> 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>. |
