This package is meant only to tide over until Sun implements a decent
millisecond timer on Windows.
To urge them to do this, please register your interest in this feature here.
A basic periodic timer with a setable period, and a "start" and a "stop" method.
As in the standard paradigm, you add event "Listeners" to JNTimers that have a callback function to perform actions when the timer fires.
Download the zip file, and unzip. Then just see the ReadMe.txt.
There are JavaDocs and example code, so it should be pretty easy to get up and going.
