Have you tried the Date Object?

strtotime possibly, seems to work with a UTC string

Sorry I think I gave you a PHP solution, I must keep off the wine! Try this:- time = Date.parse("Mon Jan 12 10:00:00 UTC+0800 2004"); newDate = new Date(time); alert(newDate.toString());

First, you need to set up functions to return the day and month names, since the JS Date object doesn't include them:

Date._dayNames = new Array(
"Sunday",
"Monday",
"Tuesday",
"Wednesday",
"Thursday",
"Friday",
"Saturday");

Date._dayNamesA = new Array(
"Sun",
"Mon",
"Tue",
"Wed",
"Thu",
"Fri",
"Sat");

Date.prototype.getDayName = function(abbreviate)
{
if (isNaN(this))
return "";
else if (true == abbreviate)
return Date._dayNamesA[this.getDay()];
else
return Date._dayNames[this.getDay()];
}

Date._monthNames = new Array(
"January",
"February",
"March",
"April",
"May",
"June",
"July",
"August",
"September",
"October",
"November",
"December");

Date._monthNamesA = new Array(
"Jan",
"Feb",
"Mar",
"Apr",
"May",
"June",
"July",
"Aug",
"Sep",
"Oct",
"Nov",
"Dec");

Date.prototype.getMonthName = function(abbreviate)
{
if (isNaN(this))
return "";
else if (true == abbreviate)
return Date._monthNamesA[this.getMonth()];
else
return Date._monthNames[this.getMonth()];
}

Then, you need to use a regular expression to parse the format string and substitute the real values:

Date._reFormat = /(\\{0,1})(dddd|ddd|dd|d|MMMM|MMM|MM|M|yyyy|yy|y|gg|g|hh|h|ss|f+|tt|t|zzz|zz|z)/gi;

Date.prototype.format = function(format)
{
if (isNaN(this)) return this.toString();
if (!format || 0 == format.length) return this.toString();

var value = this;
return format.replace(Date.\_reFormat, function($0, $1, $2)
{
    var fmt = $2;
    if (!fmt || 0 == fmt.length) return "";
    
    var ret = "";
    if ("\\\\" == $1)
    {
        ret = fmt.charAt(0);
        fmt = fmt.substr(1);
        if (0 == fmt.length) return ret;
    }
    
    switch(fmt.toLowerCase())
    {
        case "dddd":
        {
            // Full day name
            ret += value.getDayName();
            break;
        }
        case "ddd":
        {
            // Short day name
            ret += value.getDayName(true);
            break;
        }
        case "dd":
        {
            // Padded day number
            var d = value.getDate();
