我善意的回答是使用这个小小的JS: https://github.com/rhroyston/clock-js

clock.now   --> 1462248501241
clock.time  --> 11:08 PM
clock.weekday   --> monday
clock.day   --> 2
clock.month --> may
clock.year  --> 2016
clock.since(1462245888784)  --> 44 minutes
clock.until(1462255888784)  --> 2 hours
clock.what.time(1462245888784)  --> 10:24 PM
clock.what.weekday(1461968554458)   --> friday
clock.what.day('14622458887 84')    --> 2
clock.what.month(1461968554458) --> april
clock.what.year('1461968554458')    --> 2016
clock.what.time()   --> 11:11 PM
clock.what.weekday('14619685abcd')  -->     clock.js error : expected unix timestamp as argument
clock.unit.seconds  --> 1000
clock.unit.minutes  --> 60000
clock.unit.hours    --> 3600000
clock.unit.days --> 86400000
clock.unit.weeks    --> 604800000
clock.unit.months   --> 2628002880
clock.unit.years    --> 31536000000

function getTimeStamp() {
       var now = new Date();
       return ((now.getMonth() + 1) + '/' + (now.getDate()) + '/' + now.getFullYear() + " " + now.getHours() + ':'
                     + ((now.getMinutes() < 10) ? ("0" + now.getMinutes()) : (now.getMinutes())) + ':' + ((now.getSeconds() < 10) ? ("0" + now
                     .getSeconds()) : (now.getSeconds())));
}

var currentdate = new Date();

    var datetime = "Last Sync: " + currentdate.getDate() + "/"+(currentdate.getMonth()+1) 
    + "/" + currentdate.getFullYear() + " @ " 
    + currentdate.getHours() + ":" 
    + currentdate.getMinutes() + ":" + currentdate.getSeconds();

将. getday()方法更改为. getdate()，并将1添加到month，因为它从0开始计算月份。

简单地说:-

console.log(new Date().toLocaleString());

我想现在分享我的答案已经很晚了，但我认为这是值得的。

function __getCurrentDateTime(format){
    var dt=new Date(),x,date=[];
    date['d']=dt.getDate();
    date['dd']=dt.getDate()>10?dt.getDate():'0'+dt.getDate();
    date['m']=dt.getMonth()+1;
    date['mm']=(dt.getMonth()+1)>10?(dt.getMonth()+1):'0'+(dt.getMonth()+1);
    date['yyyy']=dt.getFullYear();
    date['yy']=dt.getFullYear().toString().slice(-2);
    date['h']=(dt.getHours()>12?dt.getHours()-12:dt.getHours());
    date['hh']=dt.getHours();
    date['mi']=dt.getMinutes();
    date['mimi']=dt.getMinutes()<10?('0'+dt.getMinutes()):dt.getMinutes();
    date['s']=dt.getSeconds();
    date['ss']=dt.getSeconds()<10?('0'+dt.getSeconds()):dt.getSeconds();
    date['sss']=dt.getMilliseconds();
    date['ampm']=(dt.getHours()>=12?'PM':'AM');
    x=format.toLowerCase();
    x=x.indexOf('dd')!=-1?x.replace(/(dd)/i,date['dd']):x.replace(/(d)/i,date['d']);
    x=x.indexOf('mm')!=-1?x.replace(/(mm)/i,date['mm']):x.replace(/(m)/i,date['m']);
    x=x.indexOf('yyyy')!=-1?x.replace(/(yyyy)/i,date['yyyy']):x.replace(/(yy)/i,date['yy']);
    x=x.indexOf('hh')!=-1?x.replace(/(hh)/i,date['hh']):x.replace(/(h)/i,date['h']);
    x=x.indexOf('mimi')!=-1?x.replace(/(mimi)/i,date['mimi']):x.replace(/(mi)/i,date['mi']);
    if(x.indexOf('sss')!=-1){   x=x.replace(/(sss)/i,date['sss']);  }
    x=x.indexOf('ss')!=-1?x.replace(/(ss)/i,date['ss']):x.replace(/(s)/i,date['s']);
    if(x.indexOf('ampm')!=-1){  x=x.replace(/(ampm)/i,date['ampm']);    }
    return x;
}

console.log(__getCurrentDateTime());  //returns in dd-mm-yyyy HH:MM:SS
console.log(__getCurrentDateTime('dd-mm-yyyy'));    //return in 05-12-2016
console.log(__getCurrentDateTime('dd/mm*yyyy'));    //return in 05/12*2016
console.log(__getCurrentDateTime('hh:mimi:ss'));    //return in 13:05:30

console.log (__getCurrentDateTime (' h mi: ss ampm '));//下午1:5:30返回

var datetime = new Date().toLocaleString().slice(0,9) +" "+new Date(new Date()).toString().split(' ')[4];
console.log(datetime);
