* The value of the timer is an offset relative to some arbitrary fixed

* method is useful for timing events where nanosecond precision is
* required. This is achieved by calling this method before and after the
* event, and taking the difference betweent the two times:
* </p>
* <p>
* <code>long startTime = System.nanoTime();</code><br />
* <code>... <emph>event code</emph> ...</code><br />
* <code>long endTime = System.nanoTime();</code><br />
* <code>long duration = endTime - startTime;</code><br />
* </p>
* <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.
* </p>
