如何将 EST 日期格式转换为纪元?

How to convert a EST dateformat to epoch?

我需要帮助将 2014-11-30T04:57:55.000-08:00 日期格式转换为纪元时间。请帮忙。

更新

当我使用momentjs时

var temp = "2014-11-30T04:57:55.000-08:00";
console.log(temp);
console.log(moment(temp).unix());
var d = new Date(moment(temp).unix());
console.log(d);

var translateDateWithTimeTooltip = function(value) {
    if (value == null || value == undefined)
        return value;
    var monthNames = [ "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec" ];
    var myDate = new Date( value );
    return myDate.getDate() + " " + monthNames[myDate.getMonth()] + " "+myDate.getFullYear()+ " "+myDate.getHours()+":"+myDate.getMinutes();
}

它给了我下面的结果

2014-11-30T04:57:55.000-08:00

使用moment,就是

moment("2014-11-30T04:57:55.000-08:00").unix()
