- * A demo class to show off the higher resolution available from HRTimer class
- * and to investigate the resolution offered by Java "time-related"
- * methods other than System.currentTimeMillis().<P>
- *
- * Make sure that hrtlib.dll JNI lib is in java.library.path or TimerFactory
- * will fall back to the Java system timer:
