* time, which may be in the future (making the value negative). This
|
||||
* method is useful for timing events where nanosecond precision is
|

* <code>long duration = endTime - startTime;</code><br />

* </p>
|

|
||||
* Note that the value is only nanosecond-precise, and not accurate; there
|
||||
* is no guarantee that the difference between two values is really a
|
||||
* nanosecond. Also, the value is prone to overflow if the offset
|

* exceeds 2^63.
