JavaScript Date getTimezoneOffset() Method
Below is the example of Date getTimezoneOffset() method.
- Example:
javascript
<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.
javascript
<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.
javascript
<!DOCTYPE html><html> <head> <title> JavaScript Date geTimexoneOffset() Method </title> </head> <body style="text-align: center;"> <h1 style="color: green;">GeeksforGeeks</h1> <b>JavaScript Date geTimexoneOffset() Method</b> <br /> <br /> <button onclick="gfg()">Click me</button> <script> function gfg() { // If nothing is in parameter it takes // the current date while creating // 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.
