 interval.

<DT><B>Parameters:</B><DD><CODE>initialDuration</CODE> - The number of milliseconds that must elapse

 between timer expiration notifications.  Expiration notifications are
 scheduled relative to the time of the first expiration.  If expiration
 is delayed(e.g. due to the interleaving of other method calls on the
