Complete Date Object Reference

Definition and Usage

The getTimezoneOffset() method returns the difference in minutes between Greenwich Mean Time (GMT) and local time.

Syntax

dateObject.getTimezoneOffset()

Tips and Notes

Note: The returned value of this method is not a constant, because of the practice of using Daylight Saving Time.

Note: This method is always used in conjunction with a Date object.

Example

In the following example we get the difference in minutes between Greenwich Mean Time (GMT) and local time:

<script type="text/javascript">

var d = new Date();
document.write(d.getTimezoneOffset());

</script>

The output of the code above will be:

Example 2

Now we will convert the example above into GMT +/- hours:

<script type="text/javascript">

var d = new Date()
var gmtHours = d.getTimezoneOffset()/60;
document.write("The local time zone is: GMT " + gmtHours);

</script>

The output of the code above will be:

The local time zone is: GMT -2
