在JavaScript中获取当前日期和时间

我有一个脚本，打印当前的日期和时间在JavaScript，但日期总是错误的。代码如下:

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

它应该打印18/04/2012 15:07:33和打印3/3/2012 15:07:33

这是英国时区的例子。为特定时区设置偏移量。例如:印度:+05:30，英国:+1

 function realUKTime() {
        // create Date object for current location
        var d = new Date();
        offset ='+1';
       
        // convert to msec
        // subtract local time zone offset
        // get UTC time in msec
        var utc = d.getTime() + (d.getTimezoneOffset() * 60000);

        // create new Date object for different city
        // using supplied offset
        var nd = new Date(utc + (3600000*offset));

        // return time as a string
        var s = nd.getSeconds();
        var i = nd.getMinutes();
        var h = nd.getHours();
        var cDate =  nd.getDate();
        var m =  nd.getUTCMonth();
        var y = nd.getFullYear();

       var newUkTime = nd.toDateString() + " "+ (Number(h)-1)+":"+i+':'+s
        $("#realTime").html(newUkTime);

    }

    setInterval(realUKTime(),1000);

输出::Mon 12月27日2021 12:6:3

只使用:

var d = new Date();
document.write(d.toLocaleString());
document.write("<br>");

function display_c(){   
    var refresh = 1000; // Refresh rate in milli seconds    
    mytime = setTimeout('display_ct()', refresh)    
}

function display_ct() {

    var strcount    
    var currentdate = new Date();

    document.getElementById('ct').innerHTML = currentdate.toDateString() + " " + currentdate.getHours() + ":" + currentdate.getMinutes() + ":" + currentdate.getSeconds();

    tt = display_c();   
}


id = 'ct'     // Replace in Your id

onload = "display_ct();"     // Type inside a Body Tag
