<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, uses a <i>fixed-delay</i> execution scheme, as specified in
