JavaScript Date getTimezoneOffset() Method
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.
Below are examples of Date.getTimezoneOffset() method.
Example 1:
javascript
// If nothing is in parameter it takes// the current date while creating Date objectlet date = new Date();// Extracting the time difference between// UTC and local timelet diff = date.getTimezoneOffset();//Printing on consoleconsole.log(diff); |
Output:
-330
Example 2: 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.
javascript
// Taking the date while creating Date objectlet date=new Date('Aug 32 2018 5:30');// Extracting the timedifference between// UTC and local timelet n=date.getTimezoneOffset();console.log(n) |
Output:
NaN
Example 3: In this example, we will leave the new Date blank to get the time difference between UTC and local time by a trigger.
