How to get global time(not the pc time) using javascript or jquery?

Question

I was creating a countdown timer using javascript; I can use jQuery. I want the global time not the PC time.

How could I get the global time using javascript or the jQuery?

Answer 1

Use a time API like: http://www.timeapi.org/

<script type="text/javascript">
     function myCallback(json) {
          alert(new Date(json.dateString));
     }
</script>
<script type="text/javascript" src="http://timeapi.org/utc/now.json?callback=myCallback"></script>

You can use the UTC methods from Date object: http://www.w3schools.com/jsref/jsref_obj_date.asp

var utcDate = new Date(json.dateString);
alert(utcDate.getUTCFullYear() + '-' + utcDate.getUTCMonth() + utcDAte.getUTCDate());

Answer 2

Well unless you make a request to some service that publishes like the current time of an atomic clock or something, you'll have to rely on your computers local time. As JS inherently relies on your local system.

Answer 3

The Date object has built-in methods for getting UTC values. Instead of myDate.getHours() use myDate.getUTCHours(), etc.

See the MDN reference for JavaScript date methods.
