The setTime method sets the point in time of a Date object by adding or subtracting a quantity of milliseconds to the beginning of January 1st 1970 of the Coordinated Universal Time.
Syntax
myDate.setTime( milliseconds )
With:
- milliseconds being an integer number either positive or negative equal to the difference in milliseconds since the point in time that is being assigned to the Date object and January 1st 1970 of the Coordinated Universal Time.
- myDate being an object based on the Date object.
Instead of being instantiated from a class, in JavaScript objects are created by replicating other objects. This paradigm is called Prototype-based programming.
Example
The following code uses the setTime method to add 1000 milliseconds to January 1st 1970 of the Coordinated Universal Time.
<script type="text/javascript">
var myDate = new Date();
myDate.setTime(0);
var outcome = "After adding 1000 milliseconds to the following point in time:<br /><br/>";
outcome += myDate.toUTCString() + ",<br /><br />";
myDate.setTime(1000);
outcome += "the resulting point in time is:<br /><br/> ";
outcome += myDate.toUTCString() + ".<br /><br />";
document.write(outcome);
</script>
var myDate = new Date();
myDate.setTime(0);
var outcome = "After adding 1000 milliseconds to the following point in time:<br /><br/>";
outcome += myDate.toUTCString() + ",<br /><br />";
myDate.setTime(1000);
outcome += "the resulting point in time is:<br /><br/> ";
outcome += myDate.toUTCString() + ".<br /><br />";
document.write(outcome);
</script>
Technical Details
The setTime method belongs to the Date object, it is available since the version 1.0 of JavaScript, and it is supported in all major browsers.
