 If there is one or more timer notifications before the time in the list of notifications, the notification
 is sent according to the <CODE>sendPastNotifications</CODE> flag and then, updated
 according to its period and remaining number of occurences.
 If the timer notification date remains earlier than the current date, this notification is just removed 
 from the list of notifications.

<DL>
<DD>Creates a new timer notification with the specified <CODE>type</CODE>, <CODE>message</CODE> 
 and <CODE>userData</CODE> and inserts it into the list of notifications with a given date, 
 period and number of occurences.
 <P>
 If the timer notification to be inserted has a date that is before the current date,
 the method behaves as if the specified date were the current date. <BR>
 For once-off notifications, the notification is delivered immediately. <BR>
 For periodic notifications, the first notification is delivered immediately and the
 subsequent ones are spaced as specified by the period parameter. 
 <P>
 Note that once the timer notification has been added into the list of notifications,
 its associated date, period and number of occurences cannot be updated.
 <P>
 In the case of a periodic notification, the value of parameter <i>fixedRate</i> is used to
 specify the execution scheme, as specified in <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/util/Timer.html" title="class or interface in java.util"><CODE>Timer</CODE></A>.
