1、当前时间换时间戳

var timestamp = parseInt(new Date().getTime()/1000);    // 当前时间戳
    document.write(timestamp);

2、当前时间换日期字符串

var now = new Date();
    var yy = now.getFullYear();      //年
    var mm = now.getMonth() + 1;     //月
    var dd = now.getDate();          //日
    var hh = now.getHours();         //时
    var ii = now.getMinutes();       //分
    var ss = now.getSeconds();       //秒
    var clock = yy + "-";
    if(mm < 10) clock += "0";
    clock += mm + "-";
    if(dd < 10) clock += "0";
    clock += dd + " ";
    if(hh < 10) clock += "0";
    clock += hh + ":";
    if (ii < 10) clock += '0'; 
    clock += ii + ":";
    if (ss < 10) clock += '0'; 
    clock += ss;
    document.write(clock);     //获取当前日期

3、日期字符串转时间戳

var date = '2015-03-05 17:59:00.0';
    date = date.substring(0,19);    
    date = date.replace(/-/g,'/'); 
    var timestamp = new Date(date).getTime();
    document.write(timestamp);

4、时间戳转日期字符串

var timestamp = '1425553097';
    var d = new Date(timestamp * 1000);    //根据时间戳生成的时间对象
    var date = (d.getFullYear()) + "-" + 
               (d.getMonth() + 1) + "-" +
               (d.getDate()) + " " + 
               (d.getHours()) + ":" + 
               (d.getMinutes()) + ":" + 
               (d.getSeconds());
    document.write(date);
