    可以的.代码如下:

    // 和PHP一样的时间戳格式化函数,由 bio.soyiyuan.com 转载
    // @param  {string} format    格式
    // @param  {int}    timestamp 要格式化的时间 默认为当前时间
    // @return {string}           格式化的时间字符串
    function date ( format, timestamp ) {
        var a, jsdate=((timestamp) ? new Date(timestamp*1000) : new Date());
        var pad = function(n, c){
            if( (n = n + "").length < c ) {
                return new Array(++c - n.length).join("0") + n;
            } else {
                return n;
            }
        };
        var txt_weekdays = ["Sunday","Monday","Tuesday","Wednesday", "Thursday","Friday","Saturday"];        
        var txt_ordin = {1:"st",2:"nd",3:"rd",21:"st",22:"nd",23:"rd",31:"st"};
        var txt_months = ["", "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];
        var f = {
            // Day
                d: function(){
                    return pad(f.j(), 2);
                },
                D: function(){

                // nothing special

            }
            return ret;
        });
    }

    注意js是按照代码块的方式执行的,调用方式就如php一样:

    date('Y-m-d H:i:s', 1462162610);
