 CUSTOM DATE FUNCTIONS WRITTEN BY Dest@pobox.com
	FormatDate()-  AUTOINSERTS the /'s IN A DATE
	CheckDate()- Validates Date Entered is a Valid Date

	COPY AND PASTE THE FOLLOWING INTO YOUR INPUT FIELD AND CHANGE TO APPROPRIATE FRAME LOCATION (ie: parent. or self.) :
	onchange="checkDate(this)" onkeydown="formatDate(this, window.event.keyCode,'down')" onkeyup="formatDate(this, window.event.keyCode,'up')" 
	<INPUT TYPE=text onChange="checkDate(this);printDate(this,'giorno')" onkeydown="formatDate(this, window.event.keyCode,'down')" onkeyup="formatDate(this, window.event.keyCode,'up')">
	aggiunto printDate. Devo mettere un field che si chiama giorno dove facco apparire il giorno della settimana
	per formatTime l'utilizzo è lo stesso. Vedi function.js per automatismo passaggio di campo
	SCORCIATOIE:  <%=Ab.jsDateInput(nextFocus,printDateField)%> <%=Ab.jsDateInput(nextFocus)%> <%=Ab.jsDateInput()%>
