Hi,
Get current date and time in javascrip it is little bit different. Use the below code it is working fine.

html code:
<div id="digital-clock">div>
Javascript Code:
function getDateTime() {
        var now     = new Date();
        var year    = now.getFullYear();
        var month   = now.getMonth()+1;
        var day     = now.getDate();
        var hour    = now.getHours();
        var minute  = now.getMinutes();
        var second  = now.getSeconds();
        if(month.toString().length == 1) {
             month = '0'+month;
        }
        if(day.toString().length == 1) {
             day = '0'+day;
        }
        if(hour.toString().length == 1) {
             hour = '0'+hour;
        }
        if(minute.toString().length == 1) {
             minute = '0'+minute;
        }
        if(second.toString().length == 1) {
             second = '0'+second;
        }
        var dateTime = year+'/'+month+'/'+day+' '+hour+':'+minute+':'+second;
         return dateTime;
    }

    // example usage: realtime clock
    setInterval(function(){
        currentTime = getDateTime();
        document.getElementById("digital-clock").innerHTML = currentTime;
    }, 1000);

Hi Chirwa,

please try this code:

>
<html>
<body>
<p id="p1">p>
<script>
var today = new Date();
var date = today.getFullYear() + '-' + (today.getMonth() + 1) + '-' + today.getDate();
var time = today.getHours() + ":" + today.getMinutes() + ":" + today.getSeconds();
var datedateTime = date + ' ' + time;
document.getElementById("p1").innerHTML = dateTime;
script>
body>
html>

You can use this code and display date and time

JavaScript new Date()
Using new Date(), creates a new date object with the current date and time:
"demo">

why do you want to reinvent the wheel when there is already Javascript function to show current date and time

var dateTime= new Date();

there are many overloaded version of this function which is sufficient for almost all real world date time problems.
