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

基本JS(很好学习):我们使用Date()函数，并做所有我们需要显示日期和日期在我们的自定义格式。
var myDate = new Date(); let daysList = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday']; let monthsList = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Aug', 'Oct', 'Nov', 'Dec']; let date = myDate.getDate(); let month = monthsList[myDate.getMonth()]; let year = myDate.getFullYear(); let day = daysList[myDate.getDay()]; let today = `${date} ${month} ${year}, ${day}`; let amOrPm; let twelveHours = function (){ if(myDate.getHours() > 12) { amOrPm = 'PM'; let twentyFourHourTime = myDate.getHours(); let conversion = twentyFourHourTime - 12; return `${conversion}` }else { amOrPm = 'AM'; return `${myDate.getHours()}`} }; let hours = twelveHours(); let minutes = myDate.getMinutes(); let currentTime = `${hours}:${minutes} ${amOrPm}`; console.log(today + ' ' + currentTime);
Node JS(快速简单):使用(npm安装日期和时间)安装npm页面，然后运行以下命令。
let nodeDate = require('date-and-time');
let now = nodeDate.format(new Date(), 'DD-MMMM-YYYY, hh:mm:ss a');
console.log(now);
. getday返回星期几。你需要用. getdate代替。 . getmonth返回0到11的值。您需要在结果中添加1以获得“人类”月份数。
getDay()获取星期几。3号是星期三。你需要getDate()，它会返回18。
同样，getMonth()从0开始，你需要加1来得到4(四月)。

Here is my work around clock full format with day, date, year and time and make Sure the date of your PC is set to the right date and if you are using PHP make sure in php.ini date.timezone= xx where xx your current timezone function startTime() { var today=new Date(); // 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 var suffixes = ['','st','nd','rd','th','th','th','th','th','th','th','th','th','th','th','th','th','th','th','th','th','st','nd','rd','th','th','th','th','th','th','th','st','nd','rd']; var weekday = new Array(7); weekday[0] = "Sunday"; weekday[1] = "Monday"; weekday[2] = "Tuesday"; weekday[3] = "Wednesday"; weekday[4] = "Thursday"; weekday[5] = "Friday"; weekday[6] = "Saturday"; var month = new Array(12); month[0] = "January"; month[1] = "February"; month[2] = "March"; month[3] = "April"; month[4] = "May"; month[5] = "June"; month[6] = "July"; month[7] = "August"; month[8] = "September"; month[9] = "October"; month[10] = "November"; month[11] = "December"; document.getElementById('txt').innerHTML=(weekday[today.getDay()] + ',' + " " + today.getDate()+'<sup>'+suffixes[today.getDate()]+'</sup>' + ' of' + " " + month[today.getMonth()] + " " + today.getFullYear() + ' Time Now ' + today.toLocaleTimeString()); t=setTimeout(function(){startTime()},500); } <style> sup { vertical-align: super; font-size: smaller; } </style> <html> <body onload="startTime()"> <div id="txt"></div> </body> </html>
