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.

filter_none

code

<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.
