JavaScript Date getTimezoneOffset() Method

Below is the example of Date getTimezoneOffset() method.

Example:

<script> 
  
    // If nothing is in parameter it takes 
    // the current date while creating Date object  
    var date = new Date(); 
      
    // Extracting the time difference between 
    // UTC and local time 
    var diff = date.getTimezoneOffset(); 
      
   //Printing on console 
   document.write(diff);  
  
</script> 

Output:
```
-330
```

The date.getTimezoneOffset() method is used to return the time difference between Universal Coordinated Time (UTC) and local time, in minutes. If your time zone is GMT+5, -300 (60*5) minutes will be returned. Daylight savings prevent this value from being constant.

Syntax:

date.getTimezoneOffset()

Parameter: This method does not accept any parameter.
Return Values: It returns a number representing the time difference between UTC and Local Time in minutes.

More codes for the above method are as follows:

Program 1: The date of the month should lie in between 1 to 31 because none of the months have a date greater than 31 that is why it returns NaN i.e, not a number because the date for the month does not exist.

<script> 
  
    // Taking the date while creating Date object  
    var date=new Date('Aug 32 2018 5:30'); 
      
    // Extracting the timedifference between 
    // UTC and local time 
    var n=date.getTimezoneOffset(); 
    document.write(n) 
  
</script> 

Output:

NaN

Program 2: In this example we will leave the new Date blank to get the time difference between UTC and local time by a trigger.

                // Date object 
                var date = new Date("June 29 2020 10:30"); 
  
                // Extracting the time difference between 
                // UTC and local time 
                var diff = date.getTimezoneOffset(); 
  
                //Printing on console 
                document.write(diff); 
            } 
        </script> 
    </body> 
</html> 

Output:

Note: The Universal Coordinated Time (UTC) is the time set by the World Time Standard. UTC is the same as GMT time.
