last visited cookie script

[qwertyuiop]

hello,
i have this script which shows the time the user last visited a site. It works just fine, but how can I modify the script so that it shows the time with AM and PM, not military time. Also, I'd like the script to display the date like so: Apr. 24, 2004 or even 4-24-04, like codingforums. If you're too lazy to change it, I'll be fine if you told me how to customize the date. Sorry if this is a lot.

Script:

FOR HEAD
<SCRIPT LANGUAGE = "JavaScript">
<!-- Begin Script //Display Time of last visit

var expDays = 30;
var exp = new Date(); 
exp.setTime(exp.getTime() + (expDays*24*60*60*1000));

function When(info){
// When
var rightNow = new Date()
var WWHTime = 0;
WWHTime = GetCookie('WWhenH')

WWHTime = WWHTime * 1

var lastHereFormatting = new Date(WWHTime); // Date-i-fy that number
var intLastVisit = (lastHereFormatting.getYear() * 10000)+(lastHereFormatting.getMonth() * 100) + lastHereFormatting.getDate()
var lastHereInDateFormat = "" + lastHereFormatting; // Gotta use substring functions
var dayOfWeek = lastHereInDateFormat.substring(0,3)
var dateMonth = lastHereInDateFormat.substring(4,10)
var hours = "" + lastHereFormatting.getHours()
var year = lastHereFormatting.getYear()
if (year < 1000) year+=1900
var minutes = "" + lastHereFormatting.getMinutes()
if (minutes.substring(0,1) == minutes){
minutes = "0" + minutes
}
var WWHText = dayOfWeek + ", " + dateMonth + " " + year + " at " + hours + ":" + minutes// display

SetCookie ("WWhenH", rightNow.getTime(), exp)

return WWHText;
}

function Count(info){
var psj=0;
// How many times
var WWHCount = GetCookie('WWHCount')
if (WWHCount == null) {
WWHCount = 0;
}
else{
WWHCount++;
}
SetCookie ('WWHCount', WWHCount, exp);


return WWHCount+1;
}



function set(){
// VisitorName = prompt("Who are you?", "Nada");
// SetCookie ('VisitorName', VisitorName, exp);
SetCookie ('WWHCount', 0, exp);
SetCookie ('WWhenH', 0, exp);
}

function getCookieVal (offset) { 
var endstr = document.cookie.indexOf (";", offset); 
if (endstr == -1) 
endstr = document.cookie.length; 
return unescape(document.cookie.substring(offset, endstr));
}

function GetCookie (name) { 
var arg = name + "="; 
var alen = arg.length; 
var clen = document.cookie.length; 
var i = 0; 
while (i < clen) { 
var j = i + alen; 
if (document.cookie.substring(i, j) == arg) 
return getCookieVal (j); 
i = document.cookie.indexOf(" ", i) + 1; 
if (i == 0) break; 
} 
return null;
}

function SetCookie (name, value) { 
var argv = SetCookie.arguments; 
var argc = SetCookie.arguments.length; 
var expires = (argc > 2) ? argv[2] : null; 
var path = (argc > 3) ? argv[3] : null; 
var domain = (argc > 4) ? argv[4] : null; 
var secure = (argc > 5) ? argv[5] : false; 
document.cookie = name + "=" + escape (value) + 
((expires == null) ? "" : ("; expires=" + expires.toGMTString())) + 
((path == null) ? "" : ("; path=" + path)) + 
((domain == null) ? "" : ("; domain=" + domain)) + 
((secure == true) ? "; secure" : "");
}

function DeleteCookie (name) { 
var exp = new Date(); 
exp.setTime (exp.getTime() - 1); 
// This cookie is history 
var cval = GetCookie (name); 
document.cookie = name + "=" + cval + "; expires=" + exp.toGMTString();

}
// End Script -->
</SCRIPT>



FOR BODY
<script>
if (Count()==1){
document.write("Welcome to skill f/x!")
When()
}
else if (Count()>1)
document.write("You last visited on " + When() +".")
</script>
