The client’s timezone offset could be detected by using the Date object’s getTimezoneOffset() method.
The getTimezoneOffset() method returns the time difference between UTC time and local time, that is the time offset, in minutes. This offset is changed by dividing by 60 and negating the result.
Note: The getTimezoneOffset() does not account for Daylight Savings, therefore this value may not be constant.
Syntax:
offset = new Date().getTimezoneOffset()
Example:
<!DOCTYPE html> < html > < head > < title > How to get the client timezone offset in JavaScript? </ title > </ head > < body > < h1 style = "color: green" > GeeksForGeeks </ h1 > < b > How to get the client timezone offset in JavaScript? </ b > < p > Click on the button to get the timezone offset </ p > < p >Output: < span class = "output" ></ span ></ p > < button onclick = "getTimezone()" > Get timezone </ button > <!-- Script to get the client timezone --> < script type = "text/javascript" > function getTimezone() { offset = new Date().getTimezoneOffset(); formatted = -(offset / 60); document.querySelector('.output').textContent = formatted; } </ script > </ body > </ html > |
