Answer 2

If you're having problems getting the other listed solution to work in firefox or safari you can use: http://www.datejs.com/

myDate = new Date.parse("2011-12-30")
myUTCDate = Date.UTC(myDate.getFullYear(), myDate.getMonth(), myDate.getDate(), myDate.getHours(), myDate.getMinutes(), myDate.getSeconds(), myDate.getMilliseconds());

Voila!!

Answer 3

var toUTC = function (date) {
    var newDate = new Date();
    newDate.setTime(date.getTime() + (date.getTimezoneOffset() * 60 * 1000));
    return newDate;
};

console.log(toUTC(new Date('2011-12-30')));
